3. Select the Rise Time measurement.
Rise time is typically measured between the 10% and 90% amplitude
levels of a signal; these are the default reference levels the
oscilloscope uses for rise time measurements. However, in this
example you need to measure the time the signal takes to pass
between the 0.8 V and 2.0 V levels.
You can customize the rise time measurement to measure the signal
transition time between any two reference levels. You can set each of
those reference levels to a specific percent of the signal amplitude or
to a specific level in vertical units (such as volts or amperes).

The measurement verifies that the transition time (3.842 ns) meets
the specification (≤ 10 ns).
Measuring Specific Events. Next you want to see the pulses in the
incoming digital signal, but the pulse widths vary so it is hard to
establish a stable trigger. To look at a snapshot of the digital signal,
do this step:
1. Push the SINGLE SEQ button to capture a single acquisition.

Capturing a Single-Shot Signal
The reliability of a reed relay in a piece of equipment has been poor
and you need to investigate the problem. You suspect that the relay
contacts arc when the relay opens. The fastest you can open and
close the relay is about once per minute so you need to capture the
voltage across the relay as a single-shot acquisition.
To set up for a single-shot acquisition, do these steps:
1. Adjust the vertical SCALE and horizontal SCALE to appropriate
ranges for the signal you expect to see.
2. Push the acquire MENU button.
3. Push the Resolution screen button.
4. Select Normal acquisition resolution.
5. Push the SINGLE SEQ (single sequence) button.

TDS3000B Series User Manual
Application Examples
Optimizing the Acquisition
The initial acquisition shows the relay contact beginning to open at
the trigger point. This is followed by a large spikes that indicate
contact bounce and inductance in the circuit. The inductance can
cause contact arcing and premature relay failure.
Before you take the next acquisition, you can adjust the vertical and
horizontal controls to give you a preview of how the next acquisition
might appear. As you adjust these controls, the current acquisition is
repositioned, expanded, or compressed. This preview is useful to
optimize the settings before the next single-shot event is captured.
When next acquisition is captured with the new vertical and
horizontal settings, you can see more detail about the relay contact
opening. You can now see that t he contact bounces several times as
it opens.
TDS3000B Series User Manual
2- 21
Application Examples
Using the Horizontal Zoom Function
If you want to take a close look at a particular spot on the acquired
waveform, use the horizontal zoom function. To look closely at the
point where the relay contact first begins to open, do these steps:
1. Push the zoom button
2. Use the horizontal POSITION to place the expansion point close
to where the relay contact begins to open.
3. Adjust the horizontal SCALE to magnify the waveform around
the expansion point.
The ragged waveform and the inductive load in the circuit suggest
that the relay contact may be arcing as it opens.
.

The zoom function works equally well when acquisition is running
or is stopped. Horizontal position and scale changes affect only the
display, not the next acquisition.

Saving Data to the Floppy Disk Drive
You need to do some work inside a remote site. You expect to use
the oscilloscope to look at signal waveforms and then bring
waveform information back to the office to complete a report and
perform additional analysis. To do this, take along an IBM-compatible floppy disk.
When you need to capture screen images, it may be most convenient
to first save them to disk. Once on the disk, you can load the screen
images into a PC, print hard copies with a printer attached to the
oscilloscope or your PC, or import the screen images into desktop
publishing software to produce a report.
Application Examples
Remote site
You can also save waveform data on the disk. From the disk, you can
recall waveforms to the oscilloscope display or you can import the
data into spreadsheet and Mathcad software to perform additional
analysis.
If you have oscilloscope setups that you want to use again, you also
can store them on the disk. See Save/Recall on page 3--48 for more

Saving Screen Images
While working at the remote site you discover a control signal that
you want to capture periodically to show its long-term variation. You
want to include these waveforms in a report you are preparing back
at the office.
Your desktop publishing software can import BMP graphics, so you
decide to use this format for the screen images. To setup this
configuration, do these steps:
1. Insert a floppy disk into the disk drive.
2. Push the UTILITY button.
3. Push the System screen button to select Hard Copy.
4. Push the Format screen button.
5. Select BMP Windows mono image file format (you may need
to push the -- m o r e -- screen button several times before you see
this choice).
6. Push the Port screen button.
2- 24
7. Select File to send hard copies to disk.
8. Push the hard copy button
to save the image.
The oscilloscope reads the disk directory and displays its contents.
Naming Files. It is good practice to give disk files descriptive names
so you can recognize them when you get back to the office. You will
be saving images of the control signal so you decide CNTRL is a
logical target file name to use.
TDS3000B Series User Manual
Application Examples
The oscilloscope can append an automatic sequence number to the
target file name. This feature is convenient because you want to
capture a screen image of the same control signal every five minutes.
To set up the target file name and automatic sequenc e, do these
steps:
1. Push the File Utilities screen button.
2. Use the general purpose knob to highlight the file
TEK?????.BMP.
3. Select the Rename screen button.
4. Use the screen buttons to clear the existing file name and enter
the new file name CNTRL???.BMP. The question marks are
placeholders for an automatic number sequence from 000 to 999.
5. Push the OK Accept screen button to setup the target base file
name.
6. Push MENU OFF to remove the file list from the display.

Running the Test. To capture the control signal every few minutes, do
these steps:
1. Display the signal, measurements, and menus as you want them
to appear in the screen images.
2. Push the hardcopy button
.
3. Repeat step 2 every few minutes until you are finished with the
test.
4. When you are finished, push UTILITY to see the list of
sequential files that have been saved.
The files are labeled with their sequential names as well as the time
and date each was created. You can save up to four BMP images or
approximately 35 TIFF images on a single 1.44 MB floppy disk. You
can also enable file compression (UTILITY > System: Hard Copy
> Options) to compress files in zip format so that more files can fit
on a floppy disk.

Waveform Intensity
The WAVEFORM INTENSITY adjusts the intensity of the
waveforms in the display.
The term Digital Phosphor represents the way this control simulates
the intensity control of an analog oscilloscope. At maximum
intensity, a ll waveform points are displayed at full brightness. As you
decrease the intensity, you can see intensity grading in the waveforms. The brightest parts of the waveform are the points most
frequently acquired; the dimmer parts represent less frequently
acquired points. All points decay in intensity over time unless the
display persistence is set to infinite.
Use a medium intensity setting to get an analog-oscilloscope view of
time-varying signals and those containing modulation. Use the
maximum intensity setting to view the signals the way most digital
oscilloscopes display them.
You can turn on display persistence to slow or prevent the decay of
the waveform points. With persistence on, you can simulate the
function of an analog storage oscilloscope. See page 3--23 for more
information about display persistence.
NOTE. The waveform intensity may change when you change
oscilloscope acquisition modes or horizontal scale settings. Use the
INTENSITY knob to readjust waveform intensity.

Vertical and Horizontal Preview. The vertical and horizontal preview
functions let you change the vertical and horizontal c ontrols while
acquisition is stopped or while it is waiting for the next trigger. The
oscilloscope rescales and repositions the current acquisition in
response to the new control settings, and then uses the new settings
for the next acquisition.
Preview helps you optimize these control settings before the next
acquisition; this makes it easier to work with signals that are
single-shot or have a low repetition rate.
H For more information about vertical preview, see page 3--83.
H For more information about horizontal preview, see page 3--36.
While acquisition is stopped you can make changes to other controls,
but those changes will only take affect with the next acquisition.
There is no preview for control changes other than the vertical and
horizontal controls.
The preview functions also do not affect automatic measurements,
cursor measurements, or the Math waveform. This data for these
functions is always based on the c urrent acquisition. If you rescale or
reposition a channel waveform horizontally, it may not appear
time-correlated to the automatic measurements, cursor measurements, or the Math waveform.

glitches as narrow as 1 ns.
Peak Detect is only functional for sample rates up to 125 MS/s. For
250 MS/s and faster sample rates, the oscilloscope reverts to Sample
acquisition mode, where the narrowest detectable pulse width is
1/(sample rate).

WaveAlertt Waveform Anomaly Detection. WaveAlert provides a way to
detect when a waveform deviates from a steady-state condition.
WaveAlert monitors the current waveform acquisition and compares
it to the previous DPO waveform acquisitions, using a sensitivity
value to adjust the comparision tolerance. If the current acquisition
exceeds the comparison tolerance, the oscilloscope considers the
current acquisition as an anomaly.
Anomaly
The oscilloscope can respond to an anomalous waveform by
stopping acquisitions, emitting a beep, saving the anomalous
waveform to a disk file, printing the screen image to a hard copy
device, or any combination of the above. You can also select to
highlight just the anomalous data in a waveform, or the entire
anomalous waveform.
