This product is intended for use in nonresidential areas only. Use in residential areas may cause electromagnetic interference.

Emissions which exceed the levels required by this standard may occur when this equipment is connected to a test object.

Equipment may not meet the immunity requirements of applicable listed standards when test leads and/or test probes are connected due to coupling of electromagnetic interference onto those leads/probes. To minimize the influence of electromagnetic interference, minimize the loop area between the unshielded portions of signal and associated return leads, and keep leads as far away as possible from electromagnetic disturbance sources. Twisting unshielded test leads together is an effective way to reduce loop area. For probes, keep the ground return lead as short as possible and close to the probe body. Some probes have accessory probe tip adapters to accomplish this most effectively. In all cases, observe all safety instructions for the probes or leads used.

For compliance with the EMC standards listed here, high quality shielded interface cables should be used.

Connecting probes

The oscilloscope supports probes with the following:

1. Tektronix Versatile Probe Interface (TekVPI)

These probes support two-way communication with the oscilloscope through on-screen menus and remotely through programmable support. The remote control is useful in applications like ATE where you want the system to preset probe parameters.

2. Tektronix Versatile Probe Interface (TekVPI) for Passive Probes

These probes build upon the functionality of the TekVPI interface. Each probe is matched with its corresponding oscilloscope channel, allowing the oscilloscope to optimize the signal input path. This provides AC compensation across the frequency band.

3. TPA-BNC Adapter

The TPA-BNC Adapter allows you to use TEKPROBE II probe capabilities, such as providing probe power, and passing scaling and unit information to the oscilloscope.

MDO4000C Series Oscilloscope User Manual 9

Compensating a TPP0500B or TPP1000 passive voltage probe

Your Tektronix oscilloscope can automatically compensate TPP0500B and TPP1000 probes. This eliminates the need for manual probe compensation, as is typically performed with other probes.

Each compensation generates values for a specific probe and channel combination. If you want to use the probe on another channel and desire to compensate the new probe-channel pair, you must run a new set of compensation steps for that new combination.

1. Connect the oscilloscope power cable. See Power-On on page 11.

2. Power on the oscilloscope.

3. Connect the probe connector to the oscilloscope channel, and the probe tip

and reference lead to the PROBE COMP terminals on the oscilloscope front panel.

NOTE. Connect only one probe at a time to the probe comp terminals.

When compensating TPP0500B/TPP1000 probes on the oscilloscope:

■

Each channel can store compensation values for 10 individual probes. If you try to compensate an 11th probe on a channel, the oscilloscope will delete the values for the least recently used probe and add the values for the new probe.

■

The oscilloscope will assign default compensation values to a TPP0500B or TPP1000 probe connected to the Aux In channel.

NOTE. A factory calibration will delete all stored compensation values

NOTE. A probe compensation failure is most likely due to intermittent connection

of the probe tip or ground connection during the probe compensation operation. If a failure occurs, the oscilloscope will re-use the old probe compensation values, if they existed prior to the failed probe compensation operation.

Preliminary

Compensating a non-TPP0500B or non-TPP1000 passive voltage probe

Whenever you attach a passive voltage probe for the first time to any input channel, compensate the probe to match it to the corresponding oscilloscope input channel.

If you are interested in using the automatic probe compensation procedure described above for the TPP0500B and TPP1000 probes See Compensating a

TPP0500B or TPP1000 passive voltage probe on page 15. on a non-TPP0500B/

TPP1000 Tektronix passive probe, check the instruction manual for your probe to see if it qualifies. Otherwise, to properly compensate your passive probe:

1. Follow the steps for the functional check. See Functional check on page

2. Check the shape of the displayed waveform to determine if your probe is

properly compensated.

3. If necessary, adjust your probe. Repeat as needed.

Application module free trial

A 30-day free trial is available for all application module licenses not installed in your oscilloscope. The trial period begins when you power on the oscilloscope for the first time.

After 30 days, you must purchase the module if you want to continue using the application. To see the date when your free trial period expires, push Utility on the front panel, push Utility Page on the lower menu, use multipurpose knob a to select Config, push About on the lower menu, and then push Application Modules on the side menu to see the expiration date.

Installing an application module

CAUTION. To avoid damage to the oscilloscope or application module, observe ESD (electrostatic discharge) precautions. See Power-On on page 11.

Turn off the oscilloscope power while removing or adding an application module.

See Powering off the oscilloscope on page 12.

Optional application module packages extend the capability of your oscilloscope.

You can physically install up to four application modules at one time. Application modules go into the two slots with windows in the upper right corner of the front panel. Two additional slots are directly behind the two that you can see. To use these slots, install the module with the label facing away from you.

Some of the modules have licenses which allow you to transfer the license between your application modules and the oscilloscope. You can keep each license in the module, which will allow you to move the module from one instrument to another. Alternatively, you can move the license from the module to the oscilloscope. This approach will allow you to store the module separately from the oscilloscope for safe keeping. This approach will also allow you to use more than four applications on your oscilloscope simultaneously. To transfer a license from a module to your oscilloscope or from your oscilloscope to a module:

1. Turn off the power to the oscilloscope. Insert the application modules into the oscilloscope. Turn on the power.

2. Push Utility on the front panel. If needed, push Utility Page on the lower menu and turn multipurpose knob a to select Config. Push Manage Modules and Options on the lower menu, and then push License Type on the side menu until “Modules” is selected. The licenses contained in the oscilloscope will be listed in the side menu. Push the button next to the appropriate license to transfer. You may transfer up to four licenses at one time.

3. After you turn off the power to the oscilloscope, you can remove the physical application module from the oscilloscope.

18 MDO4000C Series Oscilloscope User Manual

Installation

Preliminary

Refer to the MDO3000 and MDO4000 Series Application Module Installation Manual that came with your application module for instructions on installing and

testing an application module.

NOTE. If you transfer a license from a module to an oscilloscope, the module will not work on another oscilloscope until you transfer the license back from the oscilloscope to the module. Consider putting the physical module in an envelope or other storage with a label recording the date, module name, model and serial number of the oscilloscope which holds the license. This will help prevent confusion later if someone finds the module, installs it in some other oscilloscope, and wonders why it does not work.

Using FastAcq

FastAcq™ provides high-speed waveform capture. It is helpful in finding elusive signal anomalies. Fast acquisition mode reduces the dead time between waveform acquisitions, enabling the capture and display of transient events such as glitches and runt pulses. Fast acquisition mode can also display waveform phenomena at an intensity that reflects their rate of occurrence.

To use FastAcq:

1. Push Acquire on the front panel.

2. Push FastAcq on the lower menu.

3. Toggle FastAcq on the side menu to select On.

4. Push Waveform Palette on the side menu and use the multipurpose knob to

select the desired display palette.

MDO4000C Series Oscilloscope User Manual 41

Acquire the signal

Preliminary

The display palette lets you enhance the visibility of events. This choice uses intensity grading to indicate how often rare transients occur relative to normal signals. The choices are Temperature, Spectral, Normal and Inverted.

■

Temperature uses color-grading to indicate frequency of occurrence with hot colors like red/yellow indicating frequently occurring events and colder colors like blue/green indicating rarely occurring events.

■

Spectral uses color-grading to indicate frequency of occurrence with colder colors like blue indicating frequently occurring events and hot colors like red indicating rarely occurring events.

■

Normal uses the default channel color (like yellow for channel one) along with gray-scale to indicate frequency of occurrence where frequently occurring events are bright.

■

Inverted uses the default channel color along with gray scale to indicate frequency of occurrence where rarely occurring events are bright.

These color palettes help highlight the events that over time occur more often or, in the case of infrequent anomalies, occur less often.

How the analog acquisition modes work

Sample mode retains the first sampled point from each acquisition interval. Sample is the default mode.

Peak Detect mode uses the highest and lowest of all the samples contained in two consecutive acquisition intervals. This mode only works with real-time, noninterpolated sampling and is useful for catching high frequency glitches.

Hi Res mode calculates the average of all the samples for each acquisition interval. This mode also only works with real-time, noninterpolated sampling. Hi-Res provides a higher-resolution, lower-bandwidth waveform.

Envelope mode finds the highest and lowest record points over all acquisitions. Envelope uses Peak Detect for each individual acquisition.

Average mode calculates the average value for each record point over a userspecified number of acquisitions. Average uses Sample mode for each individual acquisition. Use average mode to reduce random noise.

7. Push Delay on the lower menu to select On when you want to delay the acquisition relative to the trigger event.

With Delay set to On, turn the Horizontal Position knob counterclockwise to increase the delay. The trigger point will move to the left and ultimately outside of the acquired waveform. Then you can adjust the Horizontal Scale knob to acquire more detail around the area of interest at the center of the screen.

When this delay is on, the trigger point separates from the horizontal expansion point. The horizontal expansion point stays at the center of the screen. The trigger point can move off the screen. When this happens, the trigger marker turns to point in the direction of the trigger point.

Use the delay feature when you want to acquire waveform detail that is separated from the trigger event by a significant interval of time. For example, you can trigger on a sync pulse that occurs once every 10 ms and then look at high-speed signal characteristics that occur 6 ms after the sync pulse.

When the delay feature is set to Off, the expansion point is tied to the trigger point so that scale changes are centered around the trigger point.

When and why to turn on MagniVu

Tektronix MagniVu acquisition technology allows you to have higher timing resolution so that you can more accurately determine edge placement and make more precise timing measurements on digital edges. Using MagniVu, you can see up to 32 times more detail than you can using normal digital channel sampling.

The MagniVu record is acquired in parallel to the main digital acquisition and is available at any time, running or stopped. MagniVu provides an ultra high resolution view of your data sampled at a maximum resolution of 60.6 ps for 10,000 points centered around the trigger.

NOTE. MagniVu centers itself around the trigger point. If you turn MagniVu on while using a large record length and you are looking somewhere other than the trigger point, then the digital signal may be off screen. In most of these cases, you can find the digital record by looking for the digital signal in the upper overview and panning accordingly.

NOTE. You should turn on MagniVu when light gray shading is displayed to indicate the uncertainty of the edge position. If the shading is not displayed, you do not need to use MagniVu. See Viewing digital channels on page 73.

Pulse Width Trigger on pulses that are less than, greater

than, equal to, or not equal to a specified time. Additionally, you can trigger when a pulse width is within or outside a range of two different specified times. You can trigger on positive or negative pulses. Pulse width triggers are primarily used on digital signals.

Timeout Trigger when no pulse is detected within a

specified time. The signal stays above or below (or either above or below) a set value for a set amount of time.

Runt Trigger on a pulse amplitude that crosses one

threshold but fails to cross a second threshold before recrossing the first. You can detect positive or negative (or either) runts, or only those wider than, less than, greater than, equal to, or not equal to a specified width. Runt triggers are primarily used on digital signals.

Trigger setup

Preliminary

Checking trigger settings

To quickly determine the settings of some key trigger parameters, check the Trigger readout at the bottom of the display. The readouts differ for edge and the advanced triggers.

1. Trigger source = channel 1.

2. Trigger slope = rising.

3. Trigger level = 0.00 V.

MDO4000C Series Oscilloscope User Manual 63

Trigger setup

Preliminary

Starting and stopping an acquisition

After you have defined the acquisition and trigger parameters, start the acquisition with Run/Stop or Single.

■

Push Run/Stop to start acquisitions. The oscilloscope acquires repeatedly until you push the button again to stop the acquisition.

■

Push Single to take a single acquisition.

■

If any RF trace and any other analog or digital waveform are active, then pressing Run/Stop to stop acquisitions will cause the oscilloscope to wait for one more trigger event before stopping. While waiting for the trigger event, the Run/Stop button will turn yellow and the Single button will turn green. Once the acquisition occurs, the Run/Stop button will turn red and the Single button will become unlit.

Single sets the trigger mode to Normal for the single acquisition.

If the Trigger Mode is set to Auto and another trigger event does not occur within the Auto trigger timeout period then an acquisition will be made and the instrument will stop.

If the Trigger mode is set to Normal, the oscilloscope will continue waiting for a trigger event to occur as long as necessary

12. Select Deskew to make display and measurement adjustments for probes that have differing propagation delays. This is especially important when using a current probe in conjunction with a voltage probe.

For best results, use a deskew fixture, such as the Tektronix 067-1686-xx.

If you do not have a deskew fixture, you can use the controls in the Deskew menu to set the oscilloscope's deskew parameters to recommended values, based on the nominal propagation delay of each probe. The oscilloscope automatically loads the nominal propagation delay values of TekVPI and TekProbe II (requires use of a TPA-BNC adaptor) probes. For other common probes, first push Select on the side menu, and select the channel to which the probe is attached. Then

Probe Model on the side menu, and select the probe model. If your probe is

push not in the list, set probe model to Other, and push Propagation Delay on the side menu and dial in its propagation delay with multipurpose knob a.

To display the recommended deskew values calculated by the oscilloscope, set Show rec. deskews on the side menu to Yes.

To set the deskew values of each channel to the recommended values, push Set

all deskews to recommended values on the side menu.

Quick Tips

■

Using Probes with the TekProbe II and TekVPI Interfaces. When you attach a probe with the TekProbe II or the TekVPI interface, the oscilloscope sets the channel sensitivity, coupling, and termination resistance automatically to match the probe requirements. Tek Probe II probes require use of the TPA-BNC Adapter.

■

The Difference Between Vertical Position and Offset. Adjust the vertical position to place the waveforms where you want to see them. The waveform baseline indicators indicate the zero Volts (or Amps) level for each waveform. If you adjust the channel's Vertical Scale, the waveform expands or contracts around the waveform's baseline indicator.

When you use the Channel<x> > More >Offset > Vertical Offset control to move a waveform, the baseline indicator no longer represents zero. Instead, it represents the level of the offset. If you adjust the channel's Vertical Scale, the waveform expands or contracts around the waveform's baseline indicator.

■

50 Ω Protection. If you select 50 Ω termination, the maximum vertical scale factor is limited to 1 V/div, except that with a 10X probe the scale factor is 10 V. If you apply excessive input voltage, the oscilloscope automatically switches to 1 MΩ termination to protect the internal 50 Ω termination. For more details, refer to the specifications in the MDO4000C Series Oscilloscopes Technical Reference.
