7. Verify that the time base operates: Confirm the following statements.

H One period of the square-wave probe-compensation signal is about five

horizontal divisions on-screen for the 200 s/div horizontal scale setting.

H Rotating the horizontal SCALE knob clockwise expands the waveform

on-screen (more horizontal divisions per waveform period), counterclockwise rotation contracts it, and returning the horizontal scale to 200 s/div returns the period to about five divisions.

H The horizontal POSITION knob positions the signal left and right

on-screen when rotated.

8. Verify horizontal delay:

a. Center a rising edge on screen:

H Set the horizontal POSITION knob so that the rising edge where the

waveform is triggered is lined up with the center horizontal graticule.

H Change the horizontal SCALE to 20 s/div. The rising edge of the

waveform should remain near the center graticule and the falling edge should be off screen.

b. Turn on and set horizontal delay:

H From the Horiz/Acq menu, select Horizontal/Acquisition

Setup....

H Click the Horizontal tab in the control window that displays.

H Click the Delay Mode button to turn delay on.

H Double click the Horiz Delay control in the control window to

display the pop-up keypad. Click the keypad buttons to set the horizontal delay to 500 s, and then click the ENTER key.

c. Verify the waveform: Verify that a falling edge of the waveform is within

a few divisions of center screen.

d. Adjust the horizontal delay: Rotate the upper multipurpose knob to

change the horizontal delay setting. Verify that the falling edge shifts horizontally. Rotate the front-panel horizontal POSITION knob. Verify that this knob has the same effect (it also adjusts delay, but only when delay mode is on).

e. Verify the delay toggle function:

H Rotate the front-panel horizontal POSITION knob to center the

falling edge horizontally on the screen.

H Change the horizontal SCALE to 40 ns/div. The falling edge of the

waveform should remain near the center graticule. If not, readjust the delay setting to center the falling edge.

H Push the front-panel DELAY button several times to toggle delay off

and on and back off again. Verify that the display switches quickly between two different points in time (the rising and falling edges of this signal).

The model comprises four high-level subsystems or processes (embodying a variety of hardware and software functions) and the data that connects them:

H Digital Signal Acquisition System. Acquires a waveform record from each

signal that you input to each channel using the following subsystems:

H Input Channels. Conditions the input signal, primarily through the use

of analog hardware, before the signal is converted to digital form.

CSA7000 Series, TDS7000 Series, & TDS6000 Series Instruments User Manual

System Overview Maps

H Trigger System. Recognizes a specific event of interest on the input trigger

signal and informs the Timebase of the occurrence of the event. Also provides recovered clock and data signals (optional on TDS 7000 Seriesand TDS6000 Series instruments).

H Timebase System. Tells the Acquisition system to start an acquisition

cycle (that is, to convert from analog to digital). In more general terms, synchronizes the capturing of digital samples in the Acquisition system to the trigger events generated from the Trigger system.

H Acquisition System. Performs the actual A/D conversion and storing of

digital samples.

H Optical-to-Electrical Converter. CSA7000 Series: Converts optical

signals to electrical signals.

H DSP Transformation System. Performs a variety of transformations or

operations, beginning with the most fundamental data element(s) in the system, the Channel Waveform(s). Waveform math operations, automatic measurements, spectral waveforms, and histogram generation are examples.

H Input/Output Systems. Provides output (and sometimes input) of instru-

ment-data elements in a form suitable to the user and also provides user input control.

Process Block Description

1. The instrument starts in the idle state; it enters this state

upon power up, upon receiving most control setting changes, or upon finishing acquisition tasks.

2. Control settings are implemented as they are requested. When you toggle the RUN/STOP control to RUN, the instrument starts the hardware.

3. The instrument acquires samples until the pretrigger portion of the waveform record (channel) being acquired is filled.

4. The instrument then begins waiting for a trigger. Acquiring continues to take place, keeping the pretrigger points current, until triggering criteria are met or a trigger is forced (Auto trigger mode only) and the instrument accepts a trigger.

H Setting Acquisition Controls: How to choose the appropriate acquisition mode

for acquiring your waveforms; how to start and stop acquisition.

H Acquisition Control Background: Background information on the data

sampling and acquisition process.

H Using Fast Acquisition Mode (CSA7000 Series & TDS7000 Series): Using

Fast Acquisition mode to capture and display transient events, such as glitches or runt pulses, often missed during longer dead times that accompany normal DSO operation.

H Using FastFrame (CSA7000 Series & TDS7000 Series): Using FastFrame to

capture many records in a larger record, and then view and measure each record individually.

H O/E Converter (CSA7000 Series): Using the Optical-to-Electrical Converter

Use input conditioning to ensure the instrument acquires the data that you want to display, measure, or otherwise process. To ensure the best possible data for displaying and further processing, do the following:

H Set the vertical scale to control the size of the vertical acquisition window

for each channel to capture part or all of the vertical amplitude of the input signal. When vertical scaling is set to capture only a fraction of the input signal range (for increased detail), the vertical offset control may be used to determine which portion of the input signal is captured by the vertical acquisition window.

Acquiring Waveforms

H Set horizontal scale to control the size of the horizontal acquisition window

to capture as much as you want of the input signal(s). Set the horizontal position to delay the window relative to a trigger and to control where in the input signal (data stream) that the horizontal acquisition window acquires.

For more background on acquisition window concepts, see Input Conditioning Background on page 3--19.

The instrument can automatically obtain and display a stable waveform of usable size. Pushing the Autoset button automatically sets up the instrument controls based on the characteristics of the input signal. Autoset is much faster and easier than a manual control-by-control setup.

The instrument can also be reset to its factory default settings.

Usage of some input conditioning controls or features may be limited when other control settings are in effect. Voltage offset is incompatible with reference waveforms because offset is an acquisition control.

Connecting and

Conditioning Your Signals

Read the following topics related to waveform acquisition; they provide details that can make it easier to set up and acquire your waveforms.

Probes and Signal Connection. Select the probe or cable that brings the signal into the instrument. Choose the probe or cable that best fits your acquisition task, whether it is connecting an active probe to test a digital circuit, or connecting to a test fixture through SMA cables to characterize a device. The connection to the instrument depends on your application.

Tektronix provides a variety of probes and cables for this product. For a list of probes available for use, see Accessories and Options on page 1--37. You can also check your Tektronix catalog for connection accessories that may support your application. More information about your probes can be found in the user manual for your probes.

Four acquisition channels are available. Each channel can be displayed as a waveform or can contribute waveform data to other waveforms (math and reference waveforms for example).

3- 10

CSA7000 Series, TDS7000 Series, & TDS6000 Series Instruments User Manual

Acquiring Waveforms

Coupling. All instruments and probes specify a maximum signal level. (See Specifications in your user manuals for exact limits.) Exceeding the limit, even momentarily, may damage the input channel. Use external attenuators, if necessary, to prevent exceeding the limits.

Coupling determines whether an input signal is directly connected to the input channel, connected through a DC blocking capacitor (TDS7104 & TDS7054), or not connected at all. These three choices are refereed to as DC coupling, AC coupling, and GND coupling.

The input resistance of each input channel is either 50 Ω or you can select 50 Ω or 1 MΩ, depending on the model. To properly terminate signals in other impedance environments, use an adapter.

All probes expect a specific coupling and input termination. Both coupling and input termination resistance are displayed on screen.

Scaling and Positioning. These key controls determine the portion of the input signal presented to the acquisition system:

H Set vertical scaling, positioning, and DC offsets to display the features of

interest on your waveform and avoid clipping. (See Note that follows.) Vertical Acquisition Window Considerations on page 3--20 describes the vertical acquisition window.

Clipped

Acquired waveform Displayed waveform

CSA7000 Series, TDS7000 Series, & TDS6000 Series Instruments User Manual

3- 11

Acquiring Waveforms

H Set horizontal scale, position, and resolution (record length) so that the

acquired waveform record includes the waveform attributes of interest with good sampling density on the waveform. The settings that you make define the horizontal acquisition window (see Horizontal Acquisition Window Considerations on page 3--23).

NOTE. Waveform data outside the vertical acquisition window is clipped; that is, the data is limited to the minimum or maximum boundaries of the vertical acquisition window. This limiting causes inaccuracies in amplitude-related measurements. Note that the acquisition window also includes 1 division above and below the displayed graticule area. See Vertical Acquisition Window Considerations on page 3--20.

Trigger and Display. Set basic trigger controls to gate waveform acquisition, and use the display to interactively scale, position, and offset waveforms. See the sections Triggering on page 3--71 and Displaying Waveforms on page 3--123.

Flexible Control Access. This manual focuses on basic setup through the front panel, and then through use of the User Interface (UI) Application displayed on screen. The online help system also documents the UI.

To Autoset the Instrument

Autoset automatically sets up the instrument controls (acquisition, display, horizontal, trigger, and vertical) based on the characteristics of the input signal.

Autoset is much faster and easier than a manual control-by-control setup. When the input signal is connected, do an autoset to automatically set up the instrument:

Overview To autoset the instrument Control elements and resources

Prerequisites

Execute

1. Signals must be connected to channels. A triggering source must be provided.

See page 3--71 in this manual for trigger setup information.

2. Push the Autoset button to execute an Autoset.

If you use Autoset when one or more channels are displayed, the instrument selects the lowest numbered channel for horizontal scaling and triggering. All channels in use are individually vertically scaled.

If you use Autoset when no channels are displayed, the instrument turns on channel one (CH 1) and scales it.

Execute

Autoset Undo

3. The Autoset Undo control window opens automatically

after an Autoset operation. Click Undo if you want to undo the last Autoset.

Only the parameters that were set by the last Autoset are undone. Parameters that you changed that are not controlled by Autoset retain their settings.

If you don’t want this window to appear, set the Utilities/User Preferences/Autoset Undo button to Off. You can still do an Autoset Undo using the Horiz/Acq menu.

To Reset the Instrument

NOTE. Autoset may change the vertical position to position the waveform appropriately. It sets vertical offset to 0 V unless an offsetable probe is attached. If you are not using an offsetable probe and your signal contains offset (such as the probe compensation signal), you may need to adjust the Vertical Offset and SCALE to display the signal.

You may want to revert to the factory default setup; if so, reset the instrument:

Input Conditioning

Background

This section contains background information that can help you more effectively set up the acquisition window of each channel.

Input. This instrument samples in real-time or random equivalent-time; both sampling systems provide pretrigger information by using the trigger to stop an already running acquisition. Both sampling systems also sample the input after it is scaled, providing improved input protection and dynamic range.

CAUTION. To prevent damage to the acquisition system, do not overdrive the inputs and observe static-safe procedures

Acquiring Waveforms

Autoset Considerations. Autoset acquires samples from the input signal and attempts to take the following actions based on the input data:

H Evaluate the amplitude range of the input signals and set the size and vertical

offset of the vertical acquisition window to acquire the signal with good resolution, but without clipping.

H Set the trigger to the approximate midlevel of the signal being autoset and

switches to edge trigger mode.

H Evaluate the signal transitions and set the horizontal scale to produce a

waveform display of 2 or 3 cycles of the input signal.

Sometimes Autoset cannot produce a correct display due to the nature of the input signal; if so, you may have to adjust the scale, trigger, and acquisition controls manually. Some conditions that can cause Autoset to fail are:

H No signal present

H Signals with extreme or variable duty cycles

H Signals with multiple or unstable signal periods

H Signals with too low amplitude

H No recognizable trigger signal

H Signals with a frequency <20 Hz

H Signals with a frequency above the bandwidth of the instrument

H Signals with high offset and low peak-to-peak variations

Vertical Acquisition Window Considerations. You can set the vertical size, position, and offset of each channel independently of other channels. Vertical scale and offset specify the vertical acquisition window for each channel. Parts of the signal amplitude that fall within the vertical window are acquired; parts outside (if any) are not.

The offset control subtracts a constant DC level from the input signal before the vertical scale factor is applied, and the vertical position control adds a constant number of divisions of signal after the scale factor is applied to the resulting difference.

Acquiring Waveforms

The vertical scale and position controls have the following effects on the vertical acquisition window and the displayed waveform:

H The vertical volts per division that you set determines the vertical size of the

acquisition window, allowing you to scale it to contain all of a waveform amplitude or only part. Figure 3--2 on page 3--22 shows two vertical acquisition windows that contain the entire waveform, but only one window contains the entire waveform in the graticule on screen.

NOTE. Amplitude-related automatic measurements (for example, peak-to-peak and RMS) will be accurate for vertical windows like those shown in Figure 3--2a and b because neither waveform is clipped (that is, both waveforms are acquired). But if signal amplitude were to extend outside the vertical acquisition window, the data acquired is clipped. Clipped data causes inaccurate results if used in amplitude-related automatic measurements. Clipping also causes inaccurate amplitude values in waveforms that are stored or exported for use in other programs.

If the scale of a math waveform is changed so that the math waveform is clipped, it will not affect amplitude measurements on that math waveform.

H The vertical position adjusts the acquisition, and therefore the display, of the

acquired waveform relative to the vertical acquisition window. Figure 3--2b shows how vertical position moves the acquired waveform vertically in the acquisition window to place the acquired waveform in the graticule display.

H As you vary the vertical position, the vertical acquisition window moves up

and down (±5 divisions) on the waveform. With input signals that are smaller than the window, it appears the waveform moves in the window. Actually, the position moves the vertical acquisition window up and down on the input signal.

The vertical offset control affects the vertical acquisition window and the displayed waveform as follows:

H The vertical range (window) is always centered around the offset value. It is

the voltage level at the middle of the vertical acquisition window. With no (zero) offset, as shown in Figure 3--2 a and b, that voltage level is zero (ground).

H As you vary vertical offset, the middle voltage level moves relative to zero.

This moves the vertical acquisition window up and down on the waveform. With input signals that are smaller than the window, it appears the waveform moves in the window. Actually, a larger signal shows what really happens: the offset moves the middle of the vertical acquisition window up and down on the input signal. Figure 3--3 shows how offset moves the acquisition window to control the portion of the waveform amplitude the window captures.
