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 Series Oscilloscopes 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.

6. Push the lower- 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. 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 around the trigger point.

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.

I2C, and CAN buses transmit the MSB (most signiﬁcant bit) ﬁrst

SPI buses do not specify a bit order

RS-232 and LIN buses transmit the LSB (least signiﬁcant bit) ﬁrst

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

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.

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.

DPO2000 and MSO2000 Series Oscilloscopes User Manual 61

Acquire the Sign

The glitch capture waveform shows signal details up to the full bandwidth of the oscilloscope. The oscilloscope captures pulses as narro

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.

Noise on your signal is random (not correlated with the trigger).

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.

62 DPO2000 and MSO2000 Series Oscilloscopes User Manual

When the signal is not ﬁltered, most measurements are taken on the foreground waveform. The min, max, and peak-to-peak m largest amplitudes in the waveform.

When the signal is ﬁltered, all measurements are taken from the ﬁltered waveform.

Dual-waveform math can be ﬁltered; the chosen noise ﬁlter frequency also applies to math. Dual-waveform math does not have a glitch capture background.

Search uses the glitch capture background, when available. This lets you better search for spikes and other anomalies.

Serial bus decode uses a full-resolution sample (foreground) waveform. When ﬁltering is active, that waveform might not be ﬁltered t

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 background waveform, up to the bandwidth of the DPO2000 or MSO2000 model.

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

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.

66 DPO2000 and MSO2000 Series Oscilloscopes User Manual

Trigger Setup

1. Adjust the position (delay) time by rotating the Horizontal Position knob.

2. Turn the horizontal Scale knob to acquire the detail th position (delay) expansion point.

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.

For I2C, push the lower-bezel Trigger On to trigger on Address/Data. Push Ad dr ess . On the side-bezel menu, push Address, and turn multipurpose knobs a and b as needed. Set the address to don’t cares (X) if you want to mask the address. The

For CAN, trig the ﬁrst byte. Set the number of bytes to match the number of bytes of interest. Use the data qualiﬁer to perform: =, !=, <, >, >=, and <= operations. Triggering on identiﬁer and data always matches the identiﬁer and data selected by the user, wi

C, SPI, and CAN in several ways:

RS-232 Bus Trigger Data Matching

You can trigger on a speciﬁc data value for RS-232 bytes. If you d eﬁned an end-of-packet character to use for RS-232 bus decoding, you can use the same end-of-packet character as a data value for trigger data matching. To do so, choose the Tx End of Packet or the Rx End of Packet character as the Trigger O n selection.

ParallelBusTriggerDataMatching

Optimum (MSO2000 series only).

parallel bus trigger performance is achieved by using only analog channels or only d igital channels

StartingandStoppinganAcquisition

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. Single sets the trigger mode to Normal

for the single acquisition.

Quick Tips

Variable persistence accumulates sampled waveform points for a speciﬁed time interval. Each sampled waveform decays independently according to the time interval. Use variable persistence for displaying infrequently appearing signal anomalies, such as glitches.

Inﬁnite persistence continuously accumulates record points until you change one of the acquisition display settings. Use inﬁnite persistence for displaying uniqu e signal anomalies, such as glitches.

XY Display Mode

The XY Display mode graphs the data in ﬁxed pairs of waveforms against one another. You can use CH1 versus CH2, and REF1 versus REF2. On four-channel models, you can also use CH3 versus CH4.

Scaling and Positioning a Waveform

Use the horizontal controls to adjust the time base, adjust the trigger point, and to examine waveform details more closely. You can also use the Wave Inspector Pan and Zoom controls to adjust the display of waveforms. (See page 103, Using Wave Inspector to Manage Long Record Length Waveforms.)

Original waveform Scaled horizon tally Positioned horizontally

Use the vertical controls to select waveforms, adjust the waveform vertical position and scale, and set input parameters. Push a channel menu button (1, 2, 3,or4) as many times as needed and the associated menu items to select, add, or remove a waveform.

Quick Tips

Preview. If you change the Position or Scale controls when the acquisition is stopped or when it is waiting for the next

trigger, the oscilloscope rescales and repositions the relevant waveforms in response to the new control settings. It simulates what you will see when you next push the RU N button. The oscilloscope uses the new settings for the next acquisition.

You may see a clipped waveform if the original acquisition went off the screen.

The math waveform, cursors, and automatic measurements remain active and valid when using preview.
