About the TDS5000B Series Oscilloscope

Welcome to the Tektronix TDS5000B Series Oscilloscopes.

The TDS5000B Series of Digital Phosphor Oscilloscopes (DPOs) provide the performance, simplicity, and connectivity needed for today’s ever-changing electronics, computer, and communications industries. The easy-to-use interface includes a large display screen and an optional touch-screen interface on a Microsoft Windows platform. Choose the methods of controlling oscilloscope operations that are most convenient for you: customary front-panel controls, menus and toolbar buttons, or the touch screen.

User interface

The user interface is built on the Windows operating system and has a similar look and feel. Switch between menu bar mode and toolbar mode by clicking Buttons or Menu in the upper-right corner of the screen. The instrument is also fully compatible with a wide range of PC hardware and software accessories such as, networked instrumentation and printers.

Optional touch screen interface

If you have the optional touch screen interface, you can access menu items and on-screen controls with the touch of a finger. The TOUCH SCREEN OFF button on the front panel toggles this option. The button is not present if your instrument was not ordered with the touch screen.

Key Features

TDS5000B Series oscilloscopes are high-performance solutions for verification, debugging, and characterization of sophisticated electronic designs. The series features exceptional signal acquisition performance, operational simplicity, and open connectivity to the design environment. Classic analog-style controls, a large display with an optional touch-sensitive screen, and graphical menus provide intuitive control. Open access to the Windows operating system enables unprecedented customization and extensibility. Key features include:

 Up to 1 GHz bandwidth and 5 GS/s real time sampling rate  Record lengths up to 16,000,000 samples  Fast acquisition at up to 100,000 acquisitions per second  1.5% DC vertical gain accuracy  Two or four input channels (each with 8-bit resolution)  Auxiliary trigger input and output  Sample, envelope, peak-detect, high-resolution, average, and waveform database acquisition

modes

 Full programmability, with an extensive GPIB command set and a message-based interface  Extensive suite of advanced triggers including edge, logic, pulse, video, communication

(optional), and sequence

 Powerful built-in measurement capability, including histograms, automatic measurements,

and measurement statistics

 Basic math as well as advanced equation editor and spectral analysis  A large 10.4 inch (264.2 mm) color display that supports color grading of waveform data to

show sample density

 Customizable MyScope control windows  An intuitive graphical user interface (UI) with online help  Internal disk storage  Wide array of probing solutions, options, and upgrades  GPIB Controller  Comprehensive Suite of Right-Click Menus

Acquisition Features

Separate Digitizers. Ensure accurate timing measurements with separate digitizers for each

channel. The digitizers can also be combined to yield a higher sample rate on a single channel.

Fast Acquisition. Acquire up to 100,000 waveforms per second to see rapidly changing

signals or intermittent signal irregularities.

Long Record Lengths. 2M per channel and 8M on a single channel is standard. Extend the

maximum record length up to 16M with memory options.

Peak Detect Acquisition Mode. See pulses as narrow as 400 ps, even at the slower time base

settings. Peak detect helps you see noise and glitches in your signal.

Acquisition Control Acquire continuously or set up to capture single shot acquisitions.

Enable or disable optional acquisition features such as equivalent time or roll mode.

Horizontal Delay. Use delay when you want to acquire a signal at a significant time interval

after the trigger point. Toggle delay on and off to quickly compare the signal at two different points in time.

Average, Envelope, Hi Res Acquisition, and WfmDB. Use Average acquisition mode to

remove uncorrelated noise from your signal. Use Envelope to capture and display the maximum variation of the signal. Use Hi Res to increase vertical resolution for lower bandwidth signals. WfmDB mode is the only mode that can be used when mask testing with an optical standard.

Signal Processing Features

Waveform Math. Set up simple math waveforms using the basic arithmetic functions

including FFT, or create more advanced math waveforms using the math expression editor. Waveform expressions can even contain measurement results and other math waveforms.

Spectral Analysis. Display spectral magnitude and phase waveforms based on your time-

domain acquisitions. Control the instrument using the traditional spectrum analyzer controls such as span, center frequency, and resolution bandwidth.

FastFrame. Use FastFrame to capture a series of triggered acquisitions at high resolution

without wasting acquisition memory on the dead time in-between the acquisitions.

Mask Testing. Use mask testing for signal violation detection and pass/fail testing. Test

signals against a user defined mask, or with Option SM you can test against industry standard masks.

Limit Testing. Use Limit Testing for pass/fail comparison with an active signal.

Display Features

Color LCD Display. Identify and differentiate waveforms easily with color coding.

Waveforms, readouts, and inputs are color matched to increase productivity and reduce operating errors.

Digital Phosphor. A Digital Phosphor Oscilloscope can clearly display intensity modulation

in your signals. The oscilloscope automatically overlays subsequent acquisitions and then decays them to simulate the writing and decay of the phosphor in an analog oscilloscope CRT (cathode-ray tube). The feature results in an intensity-graded or color-graded waveform display that shows the information in the intensity modulation.

Fit to Screen. The Digital Phosphor technology performs the compression required to

represent all record points on the screen, even at the maximum record length settings.

MultiView Zoom. To take advantage of the full resolution of the instrument, you can zoom in

on a waveform to see fine details. Both vertical and horizontal zoom are available. You can also zoom in on multiple areas of a single waveform simultaneously and on multiple waveforms at the same time.

Measurement Features

Cursors. Use cursors to take simple voltage, time, and frequency measurements. Automatic Measurements. Choose from a large palette of amplitude, time, histogram, and

communication measurements. You can customize the measurements by changing reference levels or by adding measurement gating. Statistics (mean, maximum, minimum, standard deviation and population) are available for each measurement value

Trigger Features

Simple and Advanced Trigger Types. Choose a simple edge trigger, or choose from up to

twelve advanced trigger types to help you capture a specific signal fault or event.

Dual Triggers. Use the A (main) trigger system alone or add the B trigger to capture more

complex events. You can use the A and B triggers together to set up a delay-by-time or delayby-events trigger condition.

Convenience Features

Autoset. Use Autoset to quickly set up the vertical, horizontal, and trigger controls for a

usable display.

Myscope. Allows you to create your own control windows for easy access to the controls you

use most often.

Touch Screen Interface. (Optional) You can operate all instrument functions (except the

power switch) from the touch screen interface. You can also install a mouse and keyboard to use the interface.

Toolbar or Menu Bar. You can choose a toolbar operating mode that is optimized for use

with the touch screen, or a PC-style menu-bar operating mode that is optimized for use with a mouse.

Open Desktop. The instrument is built on a Microsoft Windows software platform; the

instrument application program starts automatically when you apply power to the instrument. You can minimize the instrument application and take full advantage of the built-in PC to run other applications. Moving waveform images and data into other applications is as simple as a copy/paste operation.

Dedicated Front Panel Controls. The front panel contains knobs and buttons to provide

immediate access to the most common instrument controls. Separate vertical controls are provided for each channel. The same functions are also available through the screen interface.

Data Storage and I/O. The instrument has an optional removable hard disk drive, a floppy

disk drive, and a CD-RW drive that can be used for storage and retrieval of data. The instrument has GPIB, USB, Centronics, RS232, VGA out, extended desktop support, and Ethernet ports for input and output to other devices.

Integrated Thermal Printer (Optional). The optional built-in thermal printer allows you to

print a long continuous waveform as a banner. Banner printing shows more detail, drawing samples that might otherwise overlap on the screen.

Windows Interface Guidelines

Because the instrument uses the Microsoft Windows interface, you have open access to the Windows operating system. You can access the Windows desktop to load and run other Windowsbased applications such as Microsoft Excel, WordPad, and Paint.

Although you have access to the Windows interface, you should avoid making operating system changes that may cause problems or annoyances while trying to use the instrument. Here are some guidelines:

 The instrument has been tested with Windows 2000 Professional version. The instrument is

not intended to operate with any other version of Microsoft Windows than the one provided

on the Operating Restore CD.

 If the instrument powers on in Windows Safe Mode, the optional touch screen is inoperative.

You may need to use a mouse or keyboard to restore normal operation.

 To keep the start-up time to a minimum, keep the network support to a minimum.  Be careful when making changes in the Control Panel. Avoid making changes to any controls

with which you are unfamiliar.

 Do not change the LCD monitor color resolution (True Color 24 bit) and screen area settings

(640 by 480 pixels). If the settings change the video port may not work properly.

 Avoid using antivirus software on the instrument. If you must install it, disable it after use for

best instrument performance.

 Some third-party applications may not work properly with the instrument. If your instrument

stops working after you install third-party software, try reloading the instrument software

from the TDS5000B Series Product Software CD-ROM.

 If you do not have an external monitor attached to the instrument, avoid changing the taskbar

properties to "Always on top" and "Auto hide." The Windows taskbar may obscure buttons or

readouts on the screen. However, if you do have an external monitor attached and the

instrument is set to dual monitor mode, you can drag the taskbar from the instrument display

to the external monitor display and use these settings.

 Disable the Windows screen saver to prevent it from turning on while you are taking

measurements or viewing the display. If the screen saver comes on while taking

measurements, touch the screen (if the touch screen is installed and enabled), move the

mouse, or press any key on the attached keyboard.

 Do not delete or change any system fonts. Changing or removing fonts may affect the quality

of the display.

 Avoid changing the system Display Properties such as the Background, Appearance, Effects,

or Settings. Making such changes can affect the usability of the instrument and the touch

screen.

 Avoid making changes to the contents of the Windows folder or to the contents of the

TekScope folder.

 Avoid making changes to the BIOS settings. Changing the BIOS settings can affect the

overall operation of the instrument.

 Avoid changing the Windows power management system.

If you think that your Windows interface may cause problems with the instrument, contact your local Tektronix support center for assistance.

Using the Instrument Interface

—convenient ways you can operate the instrument

Use familiar knobs and buttons on the front panel to perform most vertical, horizontal, and triggering functions. Make quick adjustments to your displayed signals with the dedicated vertical controls for each channel.

The screen interface gives you access to the complete functionality of the instrument. The toolbar interface is optimized for optional touch screen operation. Touching (or clicking) a button on the toolbar opens a control window that you can use to select the instrument settings.

With a mouse, you may prefer to use the PC-style menu bar to open control windows or directly select many instrument settings.

Changing Control Settings

—several ways to set numerical parameters

As you configure the instrument, you may need to set a numerical parameter such as a reference level or delay time. There are several different ways to set these parameters.

 In a control window, touch or click the parameter to select it. Once selected, one of the

multipurpose knobs is assigned to the parameter. Turn the upper or lower knob (as indicated

by the knob graphic next to the parameter) to adjust the setting. Push the FINE button to use

the knob to make small changes, for example to add another decimal place for greater

accuracy.

 This online help usually refers to using the multipurpose knobs to change control settings,

although the following methods are generally available:

 Some parameters with discrete values have increment/decrement buttons. Touch or click them

to change to the next available value.

 Some parameters supply a pop-up keypad or keyboard that you can use to enter a new value.  If you have an external keyboard attached, you can also use it to type in a new value.  You can also adjust parameter values using the mouse wheel. Press the mouse wheel to access

fine mode. Press it again to return to normal mode.

Moving and Docking Control Windows

—access control settings while viewing the full screen

Control windows that open on the lower half of the screen can be set to "float" to any location. To do this, double-click the handle on the leftmost edge of the window, or click the handle and drag with the mouse to another position on the screen. The waveform display goes to full-screen mode and the control window changes its format to have a title bar.

The window can now be moved freely to any position on the screen or to a second monitor (if you have set up a dual display) by dragging it by the title bar. Note, however, that it cannot be resized. All controls on the window can be accessed and function as usual.

To dock the control window at its normal position, double-click on the title bar or float the window to its initial boundaries at the bottom half of the screen. The window snaps back into place and returns to its original format.

Control windows that appear on the rightmost side of the screen cannot be moved.

Controlling from within the Graticule Area

—things you can touch or click in the waveform graticule

Use the mouse or your finger (if the optional touch screen is installed) in the graticule area to do the following things:

 Click and drag (or touch and drag) an on-screen cursor to another position on the waveform.  Click and drag (or touch and drag) a waveform handle to change the vertical position of a waveform.  Click and drag (or touch and drag) a waveform label or other screen text that you have entered to

reposition it.

 Click and drag (or touch and drag) the horizontal reference marker to set the horizontal position.  Click and drag (or touch and drag) the trigger level marker to set the trigger level.  Click and drag (or touch and drag) across part of a waveform to select it and investigate it further.

Once the selection is made, choose one of the following actions:

—Create a Zoom waveform that covers just the selected area

—Create a histogram to analyze the selected area

—Turn on measurement gates that take measurements only in the selected area

—Cancel the selection

Access Shortcut Menus by Right-Clicking

—fast access to most common commands is available by right-clicking

Right-click on the graticule, on an object, or a readout for quick access to shortcut menus. These shortcut menus are dynamic and will change with the area or object where you right clicked. Right-click on any of the following for a dynamic shortcut menu:

 Waveform handle  Cursors  Labels  Histogram display  Masks  Templates  Trigger level marker  Readouts (the menu varies with the type of readout)  Graticule  Regions (Menu bar, Toolbar, Multipurpose Knobs)

Initializing the Instrument

—returning to a known starting point

After you complete a task, you may want to initialize the instrument settings before using the instrument with your next task. This may be especially important if you share the instrument with others; previous settings may make it difficult for you to do what you need to do.

To quickly restore the instrument to its default settings, push the front-panel DEFAULT SETUP button.

If data security is important to you, use the Tek Secure Erase feature to overwrite all internal waveforms and set up memory with null values.

Choosing and Connecting Probes

—important things to remember about probes

Choose from a wide variety of passive, active, and specialty probes to use with your instrument. The instrument automatically configures the input impedance when you attach a probe that is compatible with the TekProbe interface. Remember the following when connecting a probe:

 Adjust the low frequency compensation on most passive probes after you connect them to a

channel input.

 Compensate for gain (and offset) error in many probes. Connect the probe tip to the probe

compensation connectors and execute the built-in calibration procedure to optimize the

system accuracy.

 Compensate for propagation delay differences between voltage probes using the probe

deskew feature. Attach up to two probe tips at a time to the probe compensation terminals and

execute the deskew procedure to time align the display for each channel. The deskew

adjustment range is ±75 ns.

Creating Your Own Control Windows

—new ways to make your job easier

For quick access to the controls that you use most often, you can create your own MyScope control window. Choose from a list of controls to include and make each control window unique to your needs. MyScope allows you to have up to eight tabs in a control window, increasing the flexibility and ease of use for your unique MyScope control windows. You can create and save any number of controls windows for future use.

Triggering, Timebase, and Horizontal Delay

—a comparison with oscilloscopes of the past

The architecture of an analog oscilloscope requires its time bases and triggering to be linked. The main trigger triggers the main time base, and then you can use a delayed trigger to trigger a delayed time base. Many digital oscilloscopes have also been designed using this traditional but complex paradigm.

This instrument uses a simpler paradigm that cleanly separates the concepts of triggering and time bases. You can still do everything that you could with an analog oscilloscope and more. Now these features are easier to set up and use.

The trigger event can be simple or complex. Examples of a simple trigger are the rising edge of Channel 1 or a glitch narrower than 10 ns on Channel 2. You can set up a complex trigger where the trigger system is armed by a condition on one channel and then is triggered by a condition on another channel. In either case, simple or complex, there is just one trigger event.

The time base can be either delayed or not delayed. If it is not delayed, acquisition occurs surrounding the trigger event depending on the amount of pretrigger and posttrigger data that you have selected. If you turn on horizontal delay, you can delay the acquisition to a point well beyond the trigger event (similar in effect to a delayed time base). By alternately turning horizontal delay on and off, you can make quick, detailed comparisons between two segments of a signal that are separated from each other by a fixed amount of time. In any case, the time base is always triggered by one trigger event.

Looking at Waveform Details

—taking advantage of the full resolution of the instrument

Use the instrument MultiView Zoom function to magnify an acquisition vertically, horizontally, or in both dimensions to let you see the fine detail in your signals. The MultiView Zoom function affects only the display, not the actual waveform that is being acquired.

The fastest way to set up a Zoom display is to click (or touch) and drag across the segment of the waveform that you want to see in greater detail. Then, when you touch or click the on-screen Zoom menu item, that waveform appears in the Zoom (lower) graticule, while the entire waveform appears in the Acquisition (upper) graticule. Markers in the main graticule give you position context for what you are seeing in the Zoom graticule.

Another way to set up the MultiView Zoom function is to push the front-panel MultiZoom button. Then you can set parameters in a control window to focus your Zoom waveform on the signal segment of interest.

To see more waveform detail you can also use horizontal delay (as described in the previous topic) to focus the acquisition on a segment of a waveform separated from the trigger event by a

significant interval of time. This technique lets you increase the horizontal resolution (sample faster) on a segment of a signal, even when you cannot trigger on that particular segment.

The multizoom function also allows you to zoom on multiple areas of a waveform or on multiple waveforms simultaneously. You can lock the zoomed areas and scroll through them together or unlock the zoomed areas and scroll through them independently.

Using Fast Acquisition and DPO

—analog performance from digital technology

When you turn on FastAcq, you can acquire up to 100,000 waveforms per second. In fast acquisition mode, the "dead time" between acquisitions can be very short, approaching that of the finest analog oscilloscopes. Reduced dead time means that your chances of capturing an infrequent event are greatly improved. More time is spent acquiring and displaying your signal. And with the digital phosphor (DPO) technology, you can easily differentiate between the normal shape of your signal and that infrequent anomaly that you want to capture.

As a comparison, high quality analog real-time oscilloscopes can sweep at high repetition rates with little dead time between sweeps, which makes it possible to capture an infrequent event. Typical digital oscilloscopes (DSOs) have relatively long dead times between acquisitions; infrequent events are much more difficult to capture. With fast acquisition and digital phosphor technology, the oscilloscope acquires at a high repetition rate and then overlays the acquired information into a three-dimensional database that is updated on the display 30 times per second.

The digital phosphor oscilloscope shows you not only the displayed waveform, but also the sample density. You can choose to see sample density represented in a color palette or as shades of gray or shades of green. The DPO display in monochrome green bears a strong resemblance to the CRT of a high-quality analog oscilloscope. When you increase waveform brightness with the front-panel INTENSITY knob, areas of lower sample density appear more clearly.

DPO provides display benefits whether fast acquisition is on or off. When it is on, DPO helps you identify an infrequent anomaly in a repetitive signal, especially when either the spectral or temporal color palettes are used. The repetitive signal appears in one color and the anomalies appear in another. When fast acquisition is off, DPO improves the waveform display quality when long records are compressed for display with the 500 horizontal pixels in the graticule. The compression algorithm works with the intensity-graded display to show brighter pixels where many points have been compressed and dimmer pixels where fewer points have been compressed.

Using Waveform Math

—almost any live calculation that you can imagine

Waveform math in the instrument can be as simple as basic arithmetic or as powerful as building a complicated math expression.

With the Equation Editor, you can build a complicated math waveform expression using multiple waveform sources, constants, variables, operators, and functions. The waveform sources can be any channel, reference, or math waveform. You can enter constants with a keypad. Live results from the measurement system can be used as variables, and there is a full assortment of arithmetic operators and math functions to use. As you enter the waveform expression, you will see it appear as an equation in the control window. You can define up to four separate math waveforms (or two, if using a 2-channel model).

Using Spectral Analysis

—operate the instrument like a spectrum analyzer.

When you are displaying an FFT (spectral) math waveform, you can use either of these two ways to operate the instrument:

 Use the conventional time-domain instrument controls, such as vertical and horizontal

position and scale.

 Use the spectrum analyzer controls, such as center frequency, span, resolution bandwidth, and

reference level.

When you use the spectrum analyzer control set, the instrument automatically sets its time domain parameters, including record length and sample rate, as necessary to give you the view of the spectral waveform that you want to see. And you can switch back to using the conventional timedomain controls at any time.

Spectral waveforms can be simple magnitude or phase waveforms calculated from the data acquired on a single channel. Or you can combine spectral operations with other math operations to do complex analysis of your signals.

Characterizing a Signal

—deriving statistical information from your signals

Signal characterization begins with taking measurements. To gain even more insight into your measurements, you can add measurement statistics to calculate the average measurement value, the standard deviation, and the maximum range of the measurement value.

Another way to characterize a signal is to compile a histogram from the acquired waveform. You can set up either a vertical histogram to analyze amplitude values or a horizontal histogram to analyze timing. As an example, the vertical histogram is useful for characterizing noise and the horizontal histogram is useful for characterizing jitter.

While the histogram is being compiled from the acquired waveform, you can take continuous measurements on the histogram data to determine its mean value and other useful statistics.

Mask and Limit Testing

—applying masks and templates to waveforms for compliance testing

Mask testing is used with communication signals. You can create your own user mask or (with Option SM) use industry standard masks for compliance testing.

Limit testing allows you to compare the performance of products coming off a manufacturing line with a known good reference product or template.

You can create any number of User masks and templates for future use, however, you can only use one mask at a time and only on one channel at a time. Limit testing can be done on all four channels at the same time.

Application-Specific Measurements

—extending your measurement capability

You can load optional measurement extensions as needed to enhance the capabilities of the instrument for specific applications. These applications build on the precision signal acquisition performance of the instrument to address your specific design requirements.

Here are some examples of the application packages:

 Jitter and Timing Analysis—Use the TDSJIT3 or TDSJIT3E software to characterize the

timing performance of semiconductor systems. Analyze clock jitter, setup and hold times, and

many other timing measurements on a cycle-by-cycle basis over long, single-shot

acquisitions. Measurement statistics are presented as numerical statistics, or graphically in a

histogram, cycle trend, time trend, or spectral plot.

 Disk Drive Measurements—Use the TDSDDM2 software to measure disk drive signals

according to IDEMA standards.

 Optical Storage Analysis and Measurements—Use the TDSDVD software for automatic

amplitude and timing measurements.

 Ethernet Compliance Testing—Use the TDSET3 software to perform 10/100/1000 Base T

Ethernet compliance testing.

 USB2 Signals—Use the TDSUSB2 software to characterize USB2 signals including mask

testing and parametric testing.

 Mask and Measurement Compliance—Use the TDSCPM2 software for mask and

measurements compliance testing for ITU-T G.703 and ANSI T1.102 communications

standards.

 Power Measurements—Us the TDSPWR3 software to quickly measure and analyze power

dissipation in power supply switching devices and magnetic components.

Additional packages may be available. Contact your Tektronix representative for more information.

Connecting to a Network

—as easy as networking a PC

The instrument is built on a PC-based platform that runs Microsoft Windows as its operating system. Like any other Windows computer, you can connect the instrument to a network to enable printing, file sharing, Internet access, and other communications functions.

To make a network connection, perform the steps to enable network access. administrator for assistance.

Consult your network

Printing Hard Copy

—flexible printing options

To make hard copies, use the optional built-in thermal printer, a printer attached to one of the rearpanel ports, or connect to a network printer if your instrument is on a network. You can print the full screen, just the graticule area, or a long continuous waveform as a banner. Banner printing shows more detail, drawing samples that might otherwise overlap on the screen. Banners can only be printed on the integrated thermal printer.

The instrument uses Windows print drivers, so the process to install printers is the same as it is on any other PC.

The Page Setup dialog box contains some useful options to optimize your printing:

 Choose a print palette that is independent from the display palette. For example, you can print

grayscale images to a black and white laser printer while you choose to view the display in

color. The color and grayscale palettes both render the intensity-graded waveform information

generated by the DPO display.

 Choose the Ink Saver feature to print a hard copy with a white background. This function

saves printer ink while it preserves the color coding of the waveforms and readouts. Ink Saver

also works with the monochrome print palettes.

 Choose to print a Summary Waveform at either or both ends of your banner. This gives you a

concise overall view of the instrument display before banner printing commenced.

Using Other PC Applications

—intuitive image and data transfer

Transferring images and data from the oscilloscope to other PC applications is as simple as a copy/paste operation. With a word processing, spreadsheet, or analysis application running on the built-in PC, you can easily transfer these items using the familiar Windows clipboard system:

 Copy a full screen or graticule-only image and paste it into your document in either .BMP,

.PNG., PCX, .TIF, or .JPG format.

 Copy a waveform and paste the waveform data into a spreadsheet in a comma-delimited

(.CSV) format.

 Copy a waveform and paste the waveform data into an analysis program in Mathcad (.DAT)

format.

 Copy the displayed measurements or a snapshot of all measurements and paste them into a

document in text (.TXT) format.

 Copy the displayed measurements or a snapshot of all measurements and paste them into a

spreadsheet in a comma-delimited (.CSV) format.

Using a Second Monitor

—the convenience of a built-in PC

To optimize your access to the PC that is built into the oscilloscope, connect a keyboard, mouse, and monitor to the side panel of the instrument, and then configure Windows for dual-display mode.

In this configuration, the oscilloscope retains full dynamic oscilloscope performance while Windows and other applications such as publishing, analysis, or Web browsing tools reside on the external monitor. You can copy/paste bitmaps and waveform data from the oscilloscope to the locally running application or view Web-based reference information while using the oscilloscope for design work.

You can also drag up to five dockable HSCWs (half-screen control windows) from the TekScope application onto the display of the second monitor. For example, this feature allows you to have the Horizontal/Acquisition, the Horizontal Zoom, and the Display Setup Control Windows (half screen) open on the second monitor at the same time. In addition to the five dockable windows on the second monitor, you can have one dockable window open on the main display. If you open a seventh dockable window, the window that has not been used for the longest amount of time will automatically close.

To drag an HSCW window, click and drag on the left edge of the window.

Connecting to Other Instruments

—useful connections to other instruments

The oscilloscope provides four signal inputs and outputs that you can connect to other instrumentation:

 Use the rear-panel vertical signal output (SIGNAL OUT) to connect to a buffered version of

the signal that is attached to the Channel 3 input (4-channel models only). The typical output

amplitude is 50 mV/div 20% into a 1 MΩ load, or 25 mV/div ±20% into a 50 Ω load

 Use the rear-panel auxiliary output (AUX OUT) to obtain a TTL-compatible, negative

polarity pulse when the oscilloscope triggers.

 Use the rear-panel external reference input (EXT REF) to synchronize the oscilloscope time

base to an external 9.8  10.2 MHz reference frequency source. The reference input voltage

range is 200 mV p-p to 7V p-p.

 The trigger level range for the front-panel auxiliary input (AUX IN) is adjustable from +8 V

to –8 V. The maximum input voltage is ±20 V.

Controls and Connections

Multipurpose Knobs

The multipurpose knobs can be used to set screen interface parameters.

To use, click a control on the screen to map it to the multipurpose knob(s). Note that they are automatically mapped when certain functions are performed, for example, when the MultiView Zoom button is pushed. You can undo any mapping by right-clicking the multipurpose knob(s) and

selecting Deassign Multipurpose Knobs or from the Utilities menu select the Deassign Multipurpose Knobs command. The mapping is deassigned

until your perform that function again.

Turn the knob(s) or scroll with the mouse wheel until the desired selection appears in the readout mapped to the knob. Push the FINE button or click the mouse wheel to use the knob to make small changes, for example, to add another decimal place for greater accuracy.

When no control windows are open and cursors are turned on, the multipurpose knobs control the cursor positions.

Vertical Controls

Use the VERTICAL controls to adjust the vertical display parameters of live data channels connected to the vertical inputs. Each input channel has identical controls.

Use the dedicated channel (CH n) buttons to turn channel displays on and off. The channel button is lighted when the selected channel is on.

Use the dedicated POSITION and SCALE knobs to adjust the vertical position and scale of the waveform.

For channel waveforms (waveforms connected to the vertical inputs), the scale setting controls the vertical size of the acquisition window as well as the display scale. The range and resolution of the scale value depends on the attached probes and on any other external factors you have specified.

For reference or math waveforms, the scale setting controls the display only. Scaling these waveforms has no effect on the acquisition hardware.

Push the termination button to toggle the termination between 50 Ω and 1 MΩ. The correct termination is automatically set when you attach a probe with a TekProbe interface to the instrument. However, if you use other than a recommended probe, you may have to set the termination manually. In general, select 1 MΩ to use high impedance passive probes. Select 50 Ω to use most active probes and low impedance (Zo) probes.

Horizontal Controls

Use the HORIZONTAL controls to adjust the horizontal parameters of waveforms. The horizontal controls globally affect all displayed waveforms.

Use the dedicated POSITION knob to adjust the horizontal position of all waveforms. Use this knob to adjust the trigger point so that you can select the amount of pretrigger data or posttrigger data. In Delay Mode, this knob can be used to set the delay time.

Use the dedicated SCALE knob to adjust the horizontal scale (time base) of all channel waveforms. For math and reference waveforms, only the selected waveform is scaled.

Use the RESOLUTION knob to change the number of acquired points (record length) in the waveform, which changes the sample density. The actual resolution cannot be set directly but is derived and displayed on the horizontal readouts.

Push the DELAY button to turn on horizontal delay and then use the POSITION knob to set the delay time. Delay is useful when you want to acquire waveform details that are separated from the trigger event by a significant interval of time.

MultiView Zoom Controls

Push the MultiView Zoom button to open a magnified window or windows in the lower half of the screen.

The MultiView Zoom button is lighted when the Zoom mode is on.

The HORIZ button opens the Zoom control window and assigns the multipurpose knobs to the horizontal position and scale controls in the Zoom graticule.

The VERT button opens the Zoom control window and assigns the multipurpose knobs to the vertical position and scale controls in the Zoom graticule.

Trigger Controls

Use the TRIGGER controls to set basic trigger parameters.

By default, the instrument uses the Edge trigger. To return to the Edge trigger from any other A (main) event trigger, push the EDGE button. Pushing this button does not open the Edge Trigger control window unless another A event trigger is already displayed.

To select other trigger types, push the ADVANCED button. The Trigger Setup control window shows the previously selected, nonedge trigger type. Select one of the advanced trigger types by clicking one of the Trigger Type buttons.

Select the trigger source for the Edge trigger by pushing the up or down arrow buttons until the desired SOURCE is lighted. These buttons are only valid for the A event Edge trigger.

Push the button in the SLOPE column to toggle between positive and negative trigger slopes for the Edge trigger. The selected trigger slope is lighted. These buttons are only valid for the A event Edge trigger.

Push the button under the MODE column to toggle between normal (NORM) and auto (AUTO) modes; the selected trigger mode is lighted.

Push the LEVEL knob to set the trigger level to 50%. To set a different trigger level, rotate the LEVEL knob. The trigger level appears on the screen. The trigger level knob only affects the Edge, Width, Glitch, Timeout, and Video trigger types.

Select the trigger coupling

for the Edge trigger by pushing the up or down arrow buttons until the desired COUPLING is lighted. These buttons are only valid for the A event Edge trigger.

Run Controls

Use the Run controls to start, stop, and to monitor the status of acquisitions.

Push the RUN/STOP button to start and stop acquisitions. Push the RUN/STOP button once to stop the acquisition; the instrument displays the number of acquisitions on the screen. Push the RUN/STOP button a second time to begin acquisitions again.

Push the SINGLE button to run a single sequence of acquisitions. In Sample, Peak Detect, or High Res mode, the instrument acquires a waveform record with the first

trigger event and then stops. In Envelope, Average, or WfmDB mode, the instrument makes the specified number of acquisitions to complete the averaging or enveloping task, and then stops.

The Acquisition Status lights indicate the state of the acquisition:

 When TRIG’D is on, the instrument has recognized a valid trigger and is

filling the posttrigger portion of the waveform.

 When READY is on, the instrument can accept a valid trigger event and is

waiting for the trigger event to occur.

 When ARM is on, the instrument is filling the pretrigger portion of the

waveform record.

 When TRIG’D and READY are both on, the instrument has recognized a valid

trigger and is waiting for a delayed trigger. When the instrument recognizes a delayed trigger, it will fill in the posttrigger portion of the waveform.

 When ARM, TRIG’D, and READY are not on, the acquisitions have stopped.

General Purpose Controls

Use the following controls to do general-purpose tasks such as Autoset the instrument, print, and enable cursors.

Push the AUTOSET button to automatically set up the instrument to obtain and display a stable waveform of usable size. For information on the Autoset default settings click Autoset.

Push the DEFAULT SETUP button to reset the instrument to the factory default settings.

Push the PRINT button to make a hard copy of the screen. The printed image is sent directly to the selected (internal or attached) printer. To change the print settings, click the File menu Print command and change the settings in the Print dialog box.

Push the CURSORS button to enable cursors on the screen. The Cursor Type Setup control window opens so that you can specify the cursor parameters.

Auto-increment file name

Select Auto-increment file name to save numerous similar files without retyping the entire file

name each time.

Enter a Base file name and click Save. For the initial save the default count is 000, but you can

overwrite this number if you choose. Your first file is saved as [Basefilename][count].ext, where ext is the file extension. On subsequent saves, the instrument searches for the highest numbered file name and increases the number by one, as in Basefilename001.ext.

For example, if you are saving a series of rise time data files, you can use "Risetime" as the base

file name. Your first file is saved as Risetime000.ext, where ext is the file type extension. The next file will be Risetime001.ext, and so on.

If Count reaches 999, it is suggested that you change the base file name to Basefilename1 (for example, Risetime1) on the next save. Your next file will then be saved as Risetime1000.ext. You

will receive a warning message if you are going to overwrite any files with the same name.

The X Pos and Y Pos control values are relative to the upper-left corner of the display. The values are expressed in pixels.

Position/Scale Control Window

Access this control window from the Vertical menu Position/Scale command. Position/Scale is also available on the Math menu.

Overview

Use the Position/Scale control window to set the vertical position and scale of the selected waveform.

Use the Channel Selector tabs to select a waveform.

In addition to using the controls in this control window, you can also use the dedicated controls on the front panel to perform the same functions.

Position/Scale Control Window: Position

To Use

Use the Position control to set the vertical position of the selected

Behavior

The Position control moves the vertical position of the waveform 0.2 divisions (0.02 divisions with FINE control). Increasing the position value moves the waveform up, and decreasing the position value moves the waveform down.

The Position control differs from the Offset control; for information on the Offset control for channel waveforms refer to the Vertical Offset Control Window on page 84.

Several alternatives are available for adjusting the position of a waveform:

• Use the dedicated knob on the front panel for the selected waveform.

• Enter a value with the onscreen pop-up keypad.

• Use an attached keyboard to type a value directly into the position field.

waveform. Click the control to map it to one of the multipurpose knobs, and then use the knob to move the waveform.

Position/Scale Control Window: Scale

To Use

Use the Scale control to set the vertical scale value of the selected waveform. Click the control to map it to one of the multipurpose

Behavior

Each waveform has its own vertical scale parameter. For a signal with constant amplitude, increasing the scale causes the waveform to appear smaller. Decreasing the scale causes the waveform to appear larger.

The scale affects all waveforms, but affects channel waveforms differently:

 For channel waveforms, the scale setting controls the vertical size of the acquisition window

as well as the display scale. The range and resolution of the scale value depends on the

attached probes and any other external factors you may have specified.

 For reference or math waveforms, the scale setting controls the display only. Scaling these

waveforms has no affect on the acquisition hardware.

Several alternatives are available for adjusting the scale of a waveform:

 Use the dedicated knob on the front panel for the selected waveform.  Enter a value with the onscreen pop-up keypad.  Use an attached keyboard to type a value directly into the position field.

knobs and use the knob to move the waveform.

Vertical Offset Control Window

Access this control window from the Vertical menu Offset command.

Overview

Use the Vertical Offset control window to set the offset value of the selected waveform to shift the vertical acquisition window to match the waveform data you want to acquire.

To Use

Click a Channel button to select the vertical input channel. Click the Offset control to map it to one of the multipurpose knobs, and use the knob to set the offset value.

Behavior

The main purpose of the Offset control is to eliminate clipping the waveform. The Offset control affects the vertical acquisition window by subtracting a DC bias from the waveform. This moves the level at the vertical center of the acquisition window of the selected channel. Visualize offset as scrolling the acquisition window toward the top of a large signal for increased offset values, and scrolling toward the bottom for decreased offset values.

The Offset control affects the waveform display by defining the channel reference indicator to match the offset rather than the ground level. The offset affects only channel waveforms as compared to the position control that affects all waveforms, including math and reference waveforms. The range of the vertical offset available depends on the vertical Scale setting.

Termination Control Window

Access this control window from the Vertical menu Termination command.

Overview

Use the Termination control window to select the channel input resistance (50 Ω or 1 MΩ).

To Use

Click a Channel button at the top of the control window to select the vertical input channel. If you are not using a probe with a TekProbe interface, click one of the Termination buttons to set the termination for your probe.

Behavior

The correct termination is set automatically when you attach a probe with a TekProbe interface to the instrument. However, you may have to set the termination manually if you use a probe without the TekProbe Interface. In general, select 1 MΩ to use high impedance passive probes. Select 50 Ω to use most active probes and low impedance (Zo) probes.

Note

The 50 Ω termination becomes an open circuit if you set the channel input coupling to GND.

Consider the following when using 50 Ω termination with any channel:

 The instrument does not accurately display frequencies under 200 kHz with AC coupling.  The instrument reduces the maximum vertical scale setting for the channel to 1 V from 10 V

(to 10 V from 100 V with a 10 X probe attached), since the amplitudes appropriate for the

higher settings would overload the 50 Ω input.

 The instrument switches to 50 Ω and disables AC coupling (and switches coupling to DC if

AC is selected) if you connect an active probe. The active probes also reduce the maximum

vertical scale setting as described above. This behavior results in 50 Ω, nonAC coupling,

which is appropriate for active probes.

Note

If you remove an active probe, the instrument does not switch coupling back to 1 MΩ or AC. When you restore 1 MΩ coupling, the instrument does not return to the vertical scale setting that was reduced because of the 50 Ω selection. You must set the vertical scale, coupling, and termination appropriate for your input coupling scheme. Be sure to switch to 1 MΩ for any input signal not from a 50 Ω system.

Use the button on the front panel of each vertical input channel to manually select the

termination.

Coupling Control Window

Access this control window from the Vertical menu Coupling command.

Overview

Use the Coupling control window to select the coupling for the signal from the attached probe to the instrument.

To Use

Click a Channel button at the top of the control window to select the vertical input channel. Click one of the Coupling controls to couple the signal from the probe to the instrument.

Behavior

Select DC coupling to display the waveform with the DC and AC

components.

Select AC coupling to display the waveform with the DC component removed.

Select GND to display a zero-volt waveform. Use this selection to establish the ground reference point on the display

Bandwidth Control Window

Access this control window from the Vertical menu Bandwidth command.

Overview

Use the Bandwidth control window to filter unwanted high frequency noise from the waveform and to decrease the noise bandwidth. Specify the range of frequencies that you want to acquire by selecting the appropriate button in the control

window.

To Use

Click a Channel button at the top of the control window to select the vertical input channel. Click one of the Bandwidth buttons to select the bandwidth of frequencies that you want to acquire.

Behavior

The bandwidth refers to the range of frequencies that the instrument can acquire and display accurately with less than 3dB attenuation. Each input channel has its own bandwidth selection.

To acquire all frequencies on the selected channel, click Full. To limit frequencies above 150 MHz, click 150 MHz; to limit frequencies above 20 MHz, click 20 MHz.

To take accurate measurements, the input frequency should be much less than the rated bandwidth of the instrument. A good rule to follow is to ensure the bandwidth of the instrument system is three to five times the bandwidth of the signal that you want to measure.

Probe Calibration Control Window

Access this control window from the Vertical menu Probe Cal command.

Control Window Overview

Use the Probe Calibration control window to check the probe status and to compensate the entire signal path, from the probe tip to digitized signal, to improve the probe gain and offset accuracy.

Probe calibration is one of several features of the instrument that can optimize measurement accuracy. In addition to the probe calibration, you should also perform the following procedures:

 Probe Compensation. Use this procedure with passive

probes to compensate them to ensure maximum distortionfree inputs to the instrument and to avoid high frequency amplitude errors.

 Signal Path Compensation. Use this procedure to

compensate the internal signal path used to acquire waveforms based on the ambient temperature.

 Probe Deskew. Use this procedure to compensate probes for

delays due to differences in cable length.

The Probe Status control indicates the status of the probe calibration for the selected channel. If the probe status does not indicate Pass, the instrument may not take accurate measurements. You may want to perform the probe calibration procedure before taking any measurements with the selected probe.

Probe Calibration Control Window: Probe Status

To Use

The Probe Status control provides information on the status of the probe connected to the vertical input channel. This control provides information only; the data in the control cannot be changed directly.

Behavior

The instrument automatically detects the type of probe that you have installed and displays the probe status information.

 Initialized. The instrument was unable to detect any information from the probe in its

memory. This message often appears when you connect a probe where you have not

performed the probe calibration. You should perform the probe calibration before you use the

probe. This message also appears when you disconnect a probe from the vertical input.

 Pass. The instrument recognized the probe information stored in nonvolatile memory and that

the probe had previously passed the probe calibration procedure.

 Fail. The instrument was unable to complete the probe calibration procedure. If the Fail

message appears, try performing the signal path compensation procedure before continuing

with the probe calibration. If the Fail message still appears after performing the probe

calibration procedure, you may have a faulty probe. You should have the probe checked by

Tektronix service personnel.

Probe Calibration Control Window: Probe Calibration

To Use

Click a Channel button at the top of the control window to select the vertical input channel for the attached probe. Connect the probe tip to the appropriate signal and ground connections of the probe compensation terminals. Click Clear Probecal to clear the old calibration values. Then click Calibrate Probe to begin the calibration procedure.

Behavior

The instrument lets you compensate the probe, based on the channel to which it is connected, to improve the gain and offset accuracy of the probe. When you perform the probe calibration on the selected channel with the probe attached, you can optimize the instrument to make accurate measurements using that channel and probe. The probe calibration makes significant performance improvements when performed with active probes or older passive probes.

You should perform a probe calibration any time you want to ensure that the measurements you take are made with the most accuracy possible. You should also perform the probe calibration if you have changed probes since the last time a probe calibration was performed.

If you are compensating a passive probe, you must first compensate the low frequency response

of the probe. Refer to the Probe Compensation Procedure on page 355 for more information.

Some types of probes can be gain compensated, some can be offset compensated, and some can be compensated for both. If the probe has a TekProbe interface, the instrument can determine the type of compensation needed and will display the appropriate instructions when you perform the probe calibration procedure. Some probes cannot be compensated; for information on these probes, refer to probe calibration restrictions on page 95.

Deskew Control Window

Access this control window from the Vertical menu Deskew command.

Overview

Use the Deskew control window to compensate for propagation delays

of different length probes connected to the vertical input channels.

To Use

Connect the probes to a signal source. Use the horizontal and vertical controls to center the fastest signal on the screen. Click a channel button at the top of the control window to select the slower channel. Use the multipurpose knob to adjust the deskew time so that the two signals align. To clear the deskew value, click Set to 0.0s.

Behavior

Each input channel has its own deskew settings. Deskew compensates individual channels for probes or cables of different lengths. The instrument applies the delay values after each completed acquisition. The deskew values, which have a range of ±75 ns, do not affect triggering or the XY display format.

The deskew values are saved as part of the instrument setup. The deskew values for the selected channel will be retained until you change the probe, you restore a saved setup, or you recall the factory setup.

Deskew is supported in Fast Acquisitions mode when you acquire one or two channels. If you

acquire three or more channels, the Fast Acquisition mode is turned off and the message, Deskew not applied in FastAcq when three or more channels are acquire d, is displayed. When you switch back to acquiring one or two channels, the message, Deskew is re-enabled, is displayed and

deskew values are applied again.

Attenuation Control Window

Access this control window from the Vertical menu Attenuation command.

Overview

Use the Attenuation control window to describe the input/output ratio of any external attenuation or gain between the signal and input channels.

To Use

Click a channel button at the top of the control window to select the vertical input channel for the attached probe. To set the external attenuation as a multiplier or ratio, use the multipurpose knob to enter a value in the top control. To set the external attenuation as dB values, use the multipurpose knob to enter a value in the lower control. To set the external attenuation to the default value, click Set to Unity.

Behavior

Each input channel has its own external attenuation settings. The attenuation control is automatically set to the correct value when you attach a probe with a TekProbe interface to the instrument.

You can change the external attenuation by entering a multiplier or ratio in the top control, or by entering a dB value in the lower control. When you return the attenuation to the default value, the multiplier returns to 1, and the dB value returns to 0.

Display On/Off

Each waveform (channel, math, or reference) has its own Display button, label, and units. If you do not enter a label for the selected waveform, the label will be left blank. You can position the label anywhere on the graticule by clicking and dragging it to the desired location.

Any displayed channel waveform can be turned off without impacting any math functions, measurements, or histograms done on that waveform. You may want to turn some waveform displays off to make the remaining waveforms easier to view and analyze.

Use the dedicated front-panel CH buttons to turn the channel waveforms on or off.

To Use

Click Display to turn the channel waveform display on and off. Assign a label to the waveform with the pop-up keyboard to make it easier to identify on the screen. Set the units of vertical scale in the Units text box.

Behavior

The tab selector at the top of the Vertical Setup window identifies the channel waveform source. The Display button, the label, and units apply only to the selected waveform.

Vertical Position/Scale

To Use

Use the Position control to set the vertical position of the waveform, and the Scale control to set the vertical scale. Click on the controls and use the multipurpose knobs to change the waveforms.

Behavior

Each waveform has its own vertical Position control. The control increases or decreases the vertical position of the waveform 0.2 divisions (0.02 divisions using the FINE knob). Increasing the position value of the waveform moves the waveform up, and decreasing the position moves the waveform down.

Each waveform also has its own vertical Scale control. For a signal with a constant amplitude, increasing the scale causes the waveform to appear smaller. Decreasing the scale causes the waveform to appear larger.

For channel waveforms, the scale setting controls the vertical size of the acquisition window as well as the display scale. The range and resolution of the scale value depends on the attached probes and any other external factors that you may have specified.

Use the dedicated POSITION and SCALE knobs on the front panel to control the position and

scale of the selected waveform.

Offset

Click a channel at the top of the control window to select the vertical input channel. Click the Offset control to map it to one of the multipurpose knobs, and use the knob to set the offset value.

Behavior

Use the Offset control to eliminate clipping the waveform. The offset control affects the vertical acquisition window by subtracting a DC bias from the waveform. This moves the level at the vertical center of the acquisition window of the selected channel. Visualize offset as scrolling the acquisition window toward the top of a large signal for increased offset values and scrolling toward the bottom for decreased offset values.

The offset control affects the waveform display by defining the channel reference indicator to match the offset rather than the ground level. The offset affects only channel waveforms as compared to the position control that affects all waveforms, including math and reference waveforms.

To Use

Use the Vertical Offset controls to set the offset value of the selected waveform to shift the vertical acquisition window to match the waveform data that you want to acquire.

Termination

Note

The 50 Ω termination becomes an open circuit if you set the channel input coupling to GND.

Behavior

Consider the following when using 50 Ω termination with any channel:

 The instrument does not accurately display frequencies under 200 kHz with AC coupling.  The instrument reduces the maximum vertical scale setting for the channel to 1 V from 10 V

(to 10 V from 100 V with a X10 probe attached), since the amplitudes appropriate for the

higher settings would overload the 50 Ω input.

 The instrument switches to 50 Ω and disables AC coupling (and switches coupling to DC if

AC is selected) if you connect an active probe. The active probes also reduce the maximum

vertical scale setting as described above. This behavior results in 50 Ω, nonAC coupling,

which is appropriate for active probes.

To Use

Use the Termination controls to select the channel input resistance (50 Ω or 1 MΩ). In general, select 1 MΩ to use high impedance passive probes. Select 50 Ω to use most active probes and low impedance (Zo) probes.

Use the front-panel button for each vertical input channel to manually select the termination.

Channel Invert

Behavior

When Invert is On, the selected waveform appears mathematically inverted (flipped) on the zero volt axis. No trace of the normal waveform is left on the screen. Set Invert to Off to view the normal waveform.

An inverted channel waveform can be used for math or measurement functions. But if used as a trigger source, the normal, not inverted, waveform is used.

To Use

Use the Invert button to toggle inversion of the selected channel waveform.

Coupling Setup

To Use

Use the Coupling controls to couple the signal from the attached probe to the instrument.

Behavior

Select DC to display the waveform with the DC and the AC components. Select AC to display the waveform with the DC component removed.

Select GND to display a zero-volt waveform. Use this selection to establish the ground reference point on the display.

Note

The 50 Ω channel input termination becomes an open circuit when you select GND coupling.

Bandwidth

To Use

Use the Bandwidth controls to filter unwanted high frequency noise from the waveform and to decrease the noise bandwidth. Specify the range of frequencies that you want to acquire by clicking the appropriate button in the control window.

To acquire all frequencies on the selected channel, click Full. To limit frequencies above 150 MHz, click 150 MHz; to limit frequencies above 20 MHz, click 20 MHz.

Probe Controls

Behavior

The bandwidth refers to the range of frequencies that the instrument can acquire and display accurately with less than 3dB attenuation. Each input channel has its own bandwidth selection.

The Probe controls provide access to the Probe Calibration, Deskew, and Attenuation control windows.

Use the Probe Calibration control window (Cal) to check the status of the attached probe and to compensate the entire signal path from the probe tip to the digitized signal.

Use the Deskew control window to compensate the vertical channels for propagation delays of different length probes.

Use the Attenuation control window (Atten) to change the default attenuation or gain for the selected probe channel.

Channel Invert Control Window

Access this control window from the Vertical menu Invert command.

Overview

Use the Channel Invert control window to invert a live channel waveform.

To Use

Click one of the channel buttons to select a valid channel. Click Invert to toggle inversion of the selected waveform.

Behavior

When Invert is On, the selected waveform appears mathematically inverted (flipped) on the zero volt axis. No trace of the normal waveform is left on the screen.

Using Offset to Avoid Clipping Signals

Clipping

The circled portion of the incoming waveform is clipped, and therefore, is not acquired.

The clipped portion cannot be processed or displayed.

Offset can move the acquisition window vertically relative to the incoming waveform.

Offset removes clipping

By setting an offset to vertically shift the acquisition positive relative to the waveform, the clipped portion can be acquired.

Position, which up to now has been unchanged, can be used to position the graticule anywhere in the acquisition window.

High Impedance Probes

Most general-purpose probes have high input impedance. The high input resistance of passive probes (typically 10 MΩ) provides negligible DC loading and provides accurate DC amplitude measurements. Most passive probes require the instrument input impedance to be 1 MΩ. However, their 8 pF to 12 pF (over 60 pF for 1X) capacitive loading can distort timing and phase measurements. Use high resistance passive probes for measurements involving the following:

 Device characterization (above 15 V, thermal drift applications)  Maximum amplitude sensitivity using 1 X probe  Large voltage range (between 15 V and 500 V)  Qualitative or go/no-go measurements

Low Impedance Probes

Most low impedance (Zo) passive probes measure frequencies or timing measurements more accurately than general-purpose probes, but they take less accurate amplitude measurements. They offer a higher bandwidth to cost ratio.

The low input impedance passive probes must be terminated in a 50 Ω instrument input. Input capacitance is much lower than high impedance passive probes, typically 1 pF, but input resistance is also lower (500 Ω to 5000 Ω typically). Although that DC loading degrades amplitude accuracy, the lower input capacitance reduces high frequency loading to the circuit under test. That makes low input impedance passive probes ideal for timing and phase measurements when amplitude accuracy is not a major concern. Low input passive impedance probes are useful for measurements up to 40 V.

Active Probes

Active voltage probes often contain preamplifiers that provide high resistance and low capacitance at the probe tip. Some active voltage probes contain differential amplifiers that provide high Common Mode Rejection Ratio (CMRR).

Active current probes often contain Hall-effect sensors that extend the probe bandwidth down to DC.

Many active probes, especially high frequency probes, can drive a 50 Ω instrument input.

Probe Calibration Restrictions

Some probes cannot be calibrated or compensated. This might be because the probes have an attenuation factor greater than 20X. You will get an error message if you try to compensate such a probe.

The instrument cannot compensate for probes that may have gain and/or offset errors that are too great (>2% or >50 mV offset). If these errors are within the specified limits of your probe, you may want to use another probe. If the errors are outside the limits, have your probe checked by service personnel.

Probe calibration is not recommended for the P5050 passive probe. This probe typically has little gain and offset error, and therefore, the performance improvement after a probe calibration is not worth the time needed to do the probe calibration.

Horizontal/Acquisition Menu

Use the Horizontal/Acquisition menu options to set the horizontal and acquisition parameters for waveforms. This menu also provides access to the Zoom controls, Autoset, FastFrame, and Fast Acquisitions.

Horizontal/Acquisition Setup Control Window (Horizontal Tab)

Access this control window from the Horiz/Acq menu Horizontal/Acquisition Setup command, or the Horiz toolbar button.

Overview

Use the Horizontal/Acquisition Setup control window to set the horizontal and acquisition parameters of waveforms. The horizontal and acquisition controls are common to all channels.

The Horizontal tab controls manage the horizontal setups such as scale and position. Normally, the horizontal axis displays time information. However, in some cases, the horizontal axis can

represent frequency rather than time.

Record Length

Behavior

The maximum record length depends on the following:

 The amount of memory  The ability to combine the memory length of unused channels  The number of frames selected in FastFrame mode

To Use

Click Rec Length to map it to one of the multipurpose knobs and use the knob to change the record length. You can also use the increment/decrement buttons beneath the control, or the pop-up keypad. The record length specifies the number of sample points that make up the waveform record.

Hi Res mode requires twice the acquisition memory of other acquisition modes. When you select Hi Res mode, the instrument sets the record length accordingly to keep it from running out of memory.

Record lengths of less than 500 samples are not supported except in FastFrame, where Frame Length can be set as low as 50 samples.

When you change the record length, you can choose to hold either the sample rate or the horizontal scale constant. The remaining variables will change in response to the record length changes. See User Preferences: Record Length on page 222 to make this choice.

Horizontal Scale

Behavior

Use the Scale control to adjust the time base. This control scales all live displayed waveforms (both channel and math waveforms). You can use the Horizontal Zoom control window to change the horizontal scale and position of reference waveforms within the Zoom window(s).

To Use

Click the Scale control to map it to one of the multipurpose knobs and use the knob to change the value. You can also use the increment/decrement buttons beneath the control or the pop-up keypad.

When the horizontal delay is off, the scale expands or contracts around the trigger point. When the horizontal delay is on, the scale expands or contracts around the horizontal reference point.

The scale units depend on the waveform type. In most cases the horizontal units will be time, but they can also be frequency.

Use the dedicated front-panel HORIZONTAL SCALE knob to change the horizontal scale.

Horizontal Control Window Readouts

To Use

You cannot change the readouts of the Horizontal controls directly. The readout values are determined by other Horizontal control settings.

Behavior

Use the horizontal readouts to obtain a quick overview of the horizontal settings.

Resolution is similar to the acquisition interval. It can be thought of as the time between sample points. In most cases, the acquisition interval is the same as the resolution.

Sample Rate is the number of acquisition samples per second. The faster the sample rate, the more accurately the instrument can represent fine details in a fast signal.

Duration specifies the time across the 10-division screen.

Horizontal Delay and Horizontal Position

To Use

Use the multipurpose knob or the front-panel HORIZONTAL POSITION knob to set the horizontal position when the horizontal Delay Mode is Off.

When Delay is On, use the multipurpose knobs to set the Horiz Delay (Horizontal Delay) and the Ref Point (Reference Point).

Behavior

The Position control moves the trigger point within the acquired waveform. Use the control to select the amount of data that appears before the trigger event.

The Horiz Delay and Ref Point controls only appear when the Delay Mode is On. Horiz Delay enables the instrument to look for a trigger and then wait a specified time before acquiring data. This is useful when you know that the data you are interested in occurs a set time after the trigger. Use the Ref Point control to specify the amount of pretrigger data. The reference point is represented on the screen by a small inverted triangle.

Use the dedicated DELAY button to turn the Horizontal Delay on and off. Or, use the Horiz/Acq

menu Delay Mode On command.

Toggle Horizontal Delay on and off to quickly compare signal details at two different areas of

interest, one near the trigger location and the other centered at the delay time.

Horizontal Position/Scale Control Window

Access this control window from the Horiz/Acq menu Position/Scale command.

Overview

Use the Horizontal Position/Scale control window to set the horizontal position and scale of displayed waveforms. You can also use it to turn on horizontal delay so the acquisition window can be focused on events that occur at a fixed delay after the trigger point.

The dedicated controls on the front panel also perform the same functions.

For information on Delay Mode control see page 99, on Position control see page 99, and on Scale control see page 99 .

Horizontal Position/Scale Control Window: Delay Mode Off

When horizontal delay is off, the horizontal position control moves the trigger point within the acquired waveform. The horizontal scale control expands or contracts the waveform around the trigger point.

When horizontal delay is on, you can delay the acquisition relative to the trigger event. For more information on horizontal delay, see Horizontal Position/Scale Control Window: Horiz Delay.

Horizontal Position/Scale Control Window: Position

To Use

Click the Position control to map it to a multipurpose knob and use

Behavior

The horizontal position control moves the trigger point within the acquired waveform. You can select the amount of data that appears before and after the trigger event. To acquire waveforms leading up to the trigger event, set the horizontal position control to the maximum time setting. To acquire waveforms after the trigger event, set the horizontal position control to the minimum time setting.

the knob to change the position.

The horizontal reference point is shown as a small inverted triangle.

Use the dedicated front-panel POSITION knob to change the horizontal position.

Horizontal Position/Scale Control Window: Scale

To Use

Click the Scale control to map it to a multipurpose knob and use the knob to change the scale. You can also use the increment/decrement

Behavior

Use the Scale control to adjust the time base. The Scale control scales all live displayed waveforms at the same time.

The scale units depend on the waveform type. In most cases the horizontal units will be time. However, the horizontal units can also be frequency.

Use the dedicated front-panel HORIZONTAL SCALE knob to change the horizontal scale.

buttons beneath the control or the pop-up keypad.

Horizontal Position/Scale Control Window: Delay On

Access this control window from the Horizontal menu.

Overview

Use the Horizontal Position/Scale control window to set the horizontal delay and the horizontal scale of the displayed waveforms when the horizontal delay is on.

The dedicated controls on the front panel also perform the same functions.

For information on Delay Mode control see page 100 and on Scale control see page 101.

Horizontal Position/Scale Control Window: Horiz Delay

To Use

Click Delay Mode or push the front-panel DELAY button to activate horizontal delay. Click the Horiz Delay control, and use the multipurpose knob to set the delay time. You can also use the dedicated HORIZONTAL POSITION knob on the front panel.

Behavior

Use the Horiz Delay control to delay the acquisition relative to the trigger event. The horizontal delay feature is useful when you want to acquire waveform details that are separated from the trigger event by a significant interval of time.

For example, you can trigger the instrument on a sync pulse that occurs once every 10 ms, and then look at the high-speed characteristics that occur 6 ms after the pulse.

A convenient way to use the horizontal delay is to make quick comparisons between two

different points in time. Trigger the instrument on one area of interest and then set the horizontal delay to acquire the other area of interest. You can then toggle the horizontal delay on and off to compare details at the two points in time.
