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 an ATE (automated test environment)
where you want the system to preset
probe parameters.
2. TPA-BNC Adapter
The TPA-BNC Adapter allows you to
use Tek Probe II probe capabilities,
such as providing probe power, and
passing scaling and unit information to
the oscilloscope.
NOTE. To use a TekVPI probe and a
TPA-BNC adapter, connect a TekVPI

Application Module Free Trial
A 30-day free trial is available for all application modules 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 the front panel Utility button, push the lower-bezel Utility Pag e button, use multipurpose knob a to
select Config, and push the lower-bezel About button.
Installing an Application Module
CAUTION. To avoid damage to the oscilloscope or application module, observe ESD (electrostatic discharge) precautions.
(See page 10, Powering On the Oscilloscope.)
Turn off the oscilloscope power while removing or adding an application module.
(See page 11, Powering Off the Oscilloscope.)
Optional application module packages extend the capability of your oscilloscope. You can install one or two application
modules at one time. An application module goes into the slot with a window in the upper right corner of the front panel.
Another slot is directly behind the one that you can see. To use this slot, install the module with the label facing away from you.
For more information on how to install and test application modules, refer to the DPO2000 and MSO2000 SeriesOscilloscopes Application Module Installation manual.
NOTE. If you remove an application module, the features provided by the application module become unavailable. To
restore the features, turn off the oscilloscope power, reinstall the module and turn on the oscilloscope power.

Signal Path Compensation
Signal Path Compensation (SPC) corrects for DC inaccuracies caused by temperature variations and/or long-term drift.
You should run the SPC whenever the ambient temperature has changed by more than 10 °C or once a week if you
use vertical settings of 5 mV per division or less. Failure to do so may result in the oscilloscope not meeting warranted
performance levels at those volts per division settings.
To compensate the signal path:
1. Warm up the oscilloscope for at least
20 minutes. Remove all input signals
(probes and cables) from channel inputs.
Input signals with AC components adversely
affect SPC.

Quick Tips
To position the waveform appropriately, Autoset may change the vertical position. Autoset always sets vertical offset
to0V.
If you use Autoset when no channels are displayed, the oscilloscope turns on channel one (1) and scales it.
If you use Autoset and the oscilloscope detects a video signal, the oscilloscope automatically sets the trigger type to
video and makes other adjustments to display a stable video signal.
To manually set the oscilloscope to view a video signal in an IRE graticule:
1. Set the Trigger Type to Video.
2. Set the Vertical Scale to 143mV/div.
3. Select the proper input channel Attenuation for the probe or cable being used to feed the video signal to the
oscilloscope.
4. If necessary, connect a 75 ohm pass-through terminator to the oscilloscope input. For example, you need to add a
terminator when you use a 75-ohm cable between the video signal and the oscilloscope.

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. T he 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 s et to Off, the expansion point is tied to the trigger point so that scale changes are centered

Layer Bus Activity
Oscilloscope waveform traces from analog channels 1 to 4, digital channels D15 to D0, and the traces you see when you
choose to display a bus always show the physical layer bus activity. In the physical layer display, bits that were transmitted
earlier are to the left, and bits that were transmitted later are to the right.

NOTE. The oscilloscope displays the decode traces and event tables for all buses with the MSB on the left and LSB
on the right.
For example, an RS-232 signal (after the start bit) might be high, high, high, low, high, low, low, and high. Since the RS-232
protocol uses high for z ero and low for one, this value would be 0001 0110.
Since the decode displays the MSB first, the oscilloscope reverses the order of the bits and displays 0110 1000. If the bus
display is set to hex, the value displays as 68. If the bus display is set to ASCII, the value displays as h.

Quick Tip
Use the zoom feature to see multiple cycles of the signal in the upper part, and a single cycle in the lower part of the
display. (See page 103, Using Wave Inspector to Manage Long Record Length Waveforms.)
The lead for each digital channel has a color-coded band for easy identification. The ground leads are shorter and
have black wires.
Digital channels store a high or low state for each sample. The threshold that separates a high from a low can be set for
all the channels in GROUP 1 or in GROUP 2. The threshold can not be set for individual channels.
Reducing Unwanted Noise With FilterVu
You can use FilterVu to filter unwanted noise from your signal and still capture glitches. The oscilloscope does this by
perimposing a filtered foreground waveform over a glitch capture background waveform.
su
e filtered waveform uses a variable low-pass filter to block out noise, yielding a cleaner waveform. When the noise filter is
Th
adjusted to the minimum bandwidth setting, no more than 1% of high-frequency content that could cause the oscilloscope
to alias will pass through the filter.

When your signal is filtered, the glitch capture waveform changes color to distinguish it from the filtered waveform. When
the signal is filtered, you can independently adjust the intensity of the glitch capture waveform. When the signal is not
tered, the intensity of the glitch capture waveform depends on the overall intensity (under the Intensity button on the
fil
oscilloscope front panel).
FilterVu, Bandwidth Limit, and Averaging
You can use FilterVu, Bandwidth Limits, or Average mode to reduce noise in your signal. Each has benefits.
NOTE. FilterVu does not apply to triggering. To reduce the effects of noise on your signal while triggering, use Bandwidth
Limits or use Coupling settings.
Use FilterVu when you want to do the following:
Adjust your filter frequency with more granularity than the Bandwidth Limit provides.
Adjust all channels to the same frequency.

Increase the vertical precision of your acquisition.
NOTE. You can use FilterVu with Bandwidth Limit. You cannot use FilterVu with Average mode.
Quick Tips
You can choose to save to a file with full resolution (every point that was captured) or reduced resolution (fewer points).
When your signal is filtered, only the reduced-resolution waveform is guaranteed to be filtered to the chosen frequency.
Sometimes, the filter is unable to produce a full-resolution waveform with a frequency as low as the chosen frequency.
The frequency of the full-resolution waveform is shown in the saved file.
When the glitch capture background is on, a saved waveform file includes both the foreground and the background data.
Reference waveforms can be filtered; the chosen noise filter frequency also applies to references. Reference waveforms
also have a glitch capture background.
Reference waveforms are always saved at full resolution. Unlike saving a waveform to a file, there is no reduced
resolution option.

Using FilterVu
By default, the noise filter cutoff frequency is set to the full bandwidth of the oscilloscope when you use FilterVu. To invoke
the variable low-pass filter (noise filter), turn the multipurpose knob counterclockwise. The oscilloscope passes lower
frequency signals which results in a cleaner-looking wav eform. The noise frequency readout displays frequencies that
the oscilloscope includes in the foreground waveform. The oscilloscope displays higher frequency components in the

Trigger Setup
This section contains concepts and procedures for setting up the oscilloscope to trigger on your signal.
Triggering Concepts
Trigger Event
The trigger event establishes the time-reference point in the waveform record. All waveform record data is located in time
with respect to that point. The oscilloscope continuously acquires and retains enough sample points to fill the pretrigger
portion of the waveform record. That is the part of the waveform that is displayed before, or to the left of, the triggering
event on screen. When a trigger event occurs, the oscilloscope starts acquiring samples to build the posttrigger portion of
the waveform record, that is, the part displayed after or to the right of the trigger event. After a trigger is recognized, the
oscilloscope will not accept another trigger until the acquisition is complete and the holdoff time has expired.
Trigger Setup
Untrigg
ered display
Trigger
ed display
Trigger Modes
The trigger mode determines how the oscilloscope behaves in the absence of a trigger event:
Normal trigger mode enables the oscilloscope to acquire a waveform only when it is triggered. If no trigger occurs, the
last waveform record acquired remains on the display. If no last waveform exists, no waveform is displayed.
Auto trigger mode enables the oscilloscope to acquire a waveform even if a trigger does not occur. Auto mode uses
a timer that starts when the acquisition is started, and the pretrigger information is obtained. If a trigger event is not
detected before the timer times out, the oscilloscope forces a trigger. The length of time it waits for a trigger event
depends on the time base setting.
Auto mode, when forcing triggers in the absence of valid triggering events, does not synchronize the waveform on the
display. The waveform will appear to roll across the screen. If valid triggers occur, the display will become stable.
You can also force the oscilloscope to trigger. To do so, push the front-panel Force Trig button.

Trigger Coupling
Trigger coupling determines what part of the signal is passed to the trigger circuit. Edge triggering can use all available
coupling types: DC, Low Frequency Rejection, High Frequency Rejection, and Noise Rejection. All other trigger types
use DC coupling only.
The cutoff frequency for low frequency rejection is 65 kHz. The cutoff frequency for high frequency rejection is 85 kHz.
Horizontal Position
When Delay Mode is on, use horizontal
position to acquire waveform detail in a
region that is separated from the trigger
location by a significant interval of time.

The part of the record that occurs before the trigger is the pretrigger portion. The part that occurs after the trigger is the
posttrigger portion. Pretrigger data can help you troubleshoot. For example, to find the cause of an unwanted glitch in
your test circuit, you can trigger on the glitch and make the pretrigger period large enough to capture data before the
glitch. By analyzing what happens before the glitch, you may uncover information that helps you find the s ource of the
glitch. Alternatively, to see what is happening in your system as a result of the trigger event, make the posttrigger period
large enough to capture data after the trigger.

I2C, SPI, CAN, and LIN Bus Trigger Data Matching
Rolling window byte matching for I2C, and SPI. To use a rolling window to trigger on data, you define the number
of bytes to match. Then the oscilloscope uses a rolling window to find any match within a packet, with the window rolling
one byte at a time.
For example, if the number of bytes is one, the oscilloscope will attempt to match the first byte, second byte, third, and so
on within the packet.
If the number of bytes is two, the oscilloscope will try to match any two consecutive bytes, such as one and two, two and
three, three and four, and so on. If the oscilloscope finds a match, it will trigger.
