Acquisition Features
WaveAlertt Waveform Anomaly Detection. Automatically detects
anomalous waveforms by comparing the current waveform to the
previous waveform. Sets how the oscilloscope responds: stop on
anomaly, beep on anomaly, and save anomalous waveform to disk.
Useful for capturing signal glitches and intermittent waveform
errors. See page 3-- 13.
Separate Digitizers. Ensure accurate timing measurements with
separate digitizers for each channel. Each digitizer can sample at up
to the maximum sample rate; acquisition on all channels is always
concurrent to provide full single-shot bandwidth on each channel.

Operating Safely with Battery Power
WARNING. To avoid electric shock, connect the rear-panel ground
terminal to earth ground when operating the instrument from battery
power.
For safe operation, the oscilloscope chassis should always remain at
earth ground potential. Without a connection between the chassis and
earth ground, you can receive a shock from exposed metal on the
chassis if you connect an input to a hazardous voltage (>30 VRMS,
>42 Vpk). Protection against this condition is provided when you
attach the Tektronix-supplied grounding wire from the terminal on
the rear panel to earth ground. If you use a different grounding wire,
it must be at least 18 gauge.
If you choose not to attach the grounding wire, you are not protected
against electric shock if you connect the oscilloscope to a hazardous
voltage. You can still use the oscilloscope if you do not connect a
signal greater than 30 VRMS (42 Vpk) to the probe tip, the BNC
connector center, or the common lead. Ensure that all probe common
leads are connected to the same voltage. Also, do not connect a
grounded device, such as a printer or computer, to the oscilloscope.
WARNING. Hazardous voltages may exist in unexpected places due to
faulty circuitry in the device under test.

Customizing Your Measurements
In this example you want to verify that the incoming signal to a
piece of digital equipment meets its specifications. Specifically, the
transition time from a low logic level (0.8 V) to a high logic level
(2.0 V) must be 10 ns or less.
2.0 V

≤ 10 ns
To select the rise time measurement, do these steps:
1. Push the MEASURE button to see the measurement menu.
2. Push the CH 1 button and then the Select Measurement for Ch1
screen button.
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).

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.
The SINGLE SEQ button sets trigger parameters to the correct

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 the 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.
Remote site
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.
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
information on this capability. For information about remote control
and network printing accessories, see Appendix C: Accessories.

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, all 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

Vertical and Horizontal Preview. The vertical and horizontal preview
functions let you change the vertical and horizontal controls 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 current 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.

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

Taking Gray-Scale Measurements. Using cursors is often the best way to
take simple measurements on waveforms that contain significant
gray-scale information. The automatic measurements operate only
on the latest acquisition, not on the previous acquisitions that are
displayed in gray scale. However, you can set the cursors to surround
and measure the gray-scale area of the waveform.

position.
V Bars and FFT. When the selected waveform is an FFT waveform,
selecting V Bars and Phase sets the measurement to percent.
Tracking Mode. In cursor tracking mode, both cursors move together
when cursor 1 is selected. Enabling tracking mode automatically
selects cursor 1 as the active cursor. If cursor 2 is selected while in

nY: 2.14V
nt: -660ns
@X: -140mV

@t: 1.61ms
There are two waveform cursors; a reference cursor ( ), and a delta
cursor (). All difference (n) measurements are measured from the
reference cursor to the delta cursor. A negative nX measurement
means that the delta cursor is positioned earlier in the waveform
record than the reference cursor. A negative nY measurement means
that the delta cursor is positioned at a lower Y waveform signal level
than the reference cursor.
All absolute (@) measurements are referenced to the XY waveform’s
0, 0 origin, and show the value of the active cursor.
0, 0 Origin. The XY waveform origin is the 0 volt point of each source
waveform. Positioning both source waveform 0 volt points on the
vertical center graticule places the origin in the center of the screen.
Switching Between XY and YT. You can switch between XY and YT
display mode to see the location of the cursors in the YT waveform.
The waveform record icon at the top of the graticule also shows the
relative cursor positions in the waveform record.
Waveform Sources. You can use XY cursors on active acquisitions,
single sequence acquisitions, and reference waveforms. You need to
store both XY source waveforms in order to recreate an XY
waveform. The X axis waveform must be stored in Ref1.

When delay is off, the horizontal POSITION control moves the
trigger point within the acquired waveforms. You can select
full pretrigger, full posttrigger, or any point in between.
Use a pretrigger setting (trigger position near 100% of the record) to
acquire waveforms leading up to a trigger event. For example, if you
can trigger on an error condition, the waveforms leading up to the
error condition might tell you why the error occurred.

Slow Horizontal Settings. At horizontal SCALE settings of 40 ms/div
or slower, the oscilloscope may display waveforms in roll mode. As
the rolling waveform fills the screen, the waveform intensity and

Measure
High-Low Setup. The oscilloscope determines the 10%, 50%, or 90%
levels of the waveform and then uses them to calculate the
measurements. You can choose the method used to determine these
levels:
H Histogram sets the values statistically; it finds the most common
value either above or below the midpoint (depending on whether
it is defining the high or low reference level). Since this
statistical approach ignores short-term aberrations (overshoot,
ringing, noise), histogram is the best method for measuring
digital waveforms and pulses.
H Min-max uses the highest and lowest values of the waveform
record. This method is best for measuring waveforms that have
no large, flat portions at a common value, such as sine waves and
triangle waves.
H Auto Select chooses one of the above methods automatically
depending on the signal characteristics. Auto Select chooses the
histogram method if the histogram contains prominent peaks. If
not, Auto Select chooses the min-max method.
Measurement Gating. You can use the gating feature to limit
measurements to the portion of the waveform that is on the screen or

Upgrading Firmware. You can use the disk drive to upgrade the
oscilloscope firmware or install new application packages. See the
documentation provided with these packages for instructions.
Navigating the File System. When you insert an IBM-formatted disk
and push the File Utilities screen button, the oscilloscope shows a list
of directories and files on the disk.
Use the general purpose knob to select a directory or file. To change
the working directory, select the directory and then push the
SELECT button. To move up one directory level, select .. and then
push the SELECT button.
Automatic File Numbering. The oscilloscope gives all files created by
the oscilloscope the default name TEK?????, where the question
marks are placeholders for an automatic number sequence from
00000 to 99999.
You can change the TEK????? file to a new name with up to eight
characters. If you use fewer than eight characters and include trailing
question marks, the oscilloscope numbers the files sequentially if
more than one are saved with the same base name.
For example, if you rename the TEK?????.ISF file to TEST??.ISF
for a series of saved waveforms, the oscilloscope saves the first one
as TEST00.ISF, the second one as TEST01.ISF, up to the last one as
TEST99.ISF.

External Trigger. The trigger level range for the EXT setting is - 0.8 V
to +0.8 V. The trigger level range for the EXT/10 setting is - 8 V to
+8 V.
For best external trigger performance, apply a square-wave signal
with amplitude greater than the specified minimum level range and
with well-defined transitions.
Alternating Trigger. Alternating trigger sequentially uses each active
channel as a trigger source, from the lowest-numbered active
channel to the highest-numbered active channel. Alternating trigger
is available in all trigger menus except for logic triggers.
Alternating trigger uses the current trigger settings to trigger on all
active channels; there is not a separate trigger setup for each
channel. Therefore, the trigger settings must be able to trigger on all
active signals in order to produce a stable triggered display. If one or
more of the source signals do not meet the trigger settings, the
oscilloscope either waits for that source channel to trigger (Normal
trigger mode) or autotriggers (Auto trigger mode).
Due to image persistence, all alternating trigger active channels may
appear to be synchronized. However, this does not mean that the
displayed signals are synchronized. Also, alternating trigger does not
use EXT, EXT/10, or Line signals as trigger sources.

Vertical Preview. When you change the vertical POSITION or SCALE
controls while the acquisition is stopped or it is waiting for the next
trigger, the oscilloscope rescales and repositions the selected
waveform in response to the new vertical control settings. You may
see a clipped waveform if the original acquisition went off the
screen. The oscilloscope then uses the new settings for the next
acquisition.
In contrast to horizontal preview, the math waveform, cursors, and
automatic measurements remain active and valid when using vertical
preview.
The Difference Between Vertical Position and Offset. Vertical position is a
display function. Adjust the vertical position to place the waveforms
where you want to see them. The waveform baseline locations track
adjustments made to their positions.
When you adjust vertical offset you see a similar effect, but it is
actually quite different. Vertical offset is applied before the
oscilloscope preamplifier and can be used to increase the effective
dynamic range of the inputs. For example, you can use vertical offset
to look at small variations in a large DC voltage. Set the vertical
offset to match the nominal DC voltage and the signal appears in the
center of the screen.

Scaling and Positioning the Math Waveform To position or scale a math
waveform, select the math waveform and then adjust it with a
vertical POSITION or SCALE control. You can do this whether
acquisition is running or is stopped.
Math Interaction with Preview. If you select a channel waveform and
then adjust the vertical POSITION or SCALE control while the
acquisition is stopped, the math waveform remains fixed. It does not
track the changes you see to the channel waveform. The same is true
if you adjust the horizontal POSITION or SCALE control under
these conditions.
Gray-Scale Restriction. Math waveforms are always based on the most
current acquisitions and do not contain any gray-scale information.
Source Waveform Screen Position. When displaying dual-waveform
math waveforms, make sure that the source waveforms do not extend

Probe Guard
A guard around the probe body provides a finger barrier for
protection from electric shock.
Guard
WARNING. To avoid electric shock when using the probe, keep fingers
behind the guard on the probe body.
To avoid electric shock when using the probe, do not touch metallic
portions of the probe head while connected to a voltage source.
Ground Leads
Always use a ground lead when you probe a circuit to minimize
noise pickup and signal aberrations. Connecting the ground lead to a
point near the signal source usually provides the best results.
Long ground leads can cause false ringing and aberrations in the
acquired waveform that are not in the actual signal. To see the best
signal fidelity, use the shortest possible ground lead.

The oscilloscope supplies power to active probes. You can use the
following active probes as long as the total power required by the
probes does not exceed the capacity of the oscilloscope. To
determine the total probe load, add the load factors for all probes you
want to use. The oscilloscope can supply power to this combination
if the sum of the load factors equals 10 or less. All passive probes
have a load factor of zero.

General Care
Protect the oscillscope from adverse weather conditions. The
oscilloscope is not water resistant.
Do not store or leave the oscilloscope where the LCD display will be
exposed to direct sunlight for long periods of time.
CAUTION. To avoid damage to the oscilloscope, do not expose it to
sprays, liquids, or solvents.
Cleaning
Inspect the oscillosope as often as operating conditions require. To
clean the oscilloscope exterior, perform the following steps:
1. Remove loose dust on the outside of the oscilloscope with a
lint-free cloth. Use care to avoid scratching the glass display
filter.
2. Use a soft cloth or paper towel dampened with water to clean the
oscilloscope. You can use a 75% isopropyl alcohol solution for
more efficient cleaning.
CAUTION. To avoid damage to the surface of the oscilloscope, do not
use any abrasive or chemical cleaning agents.

Appendix G: Ethernet Setup
The following sections describe how to set up the TDS3000B Series
oscilloscope for network hard copy printing and remote programmability or access. The TDS3000B requires a straight-through 10BaseT
cable with RJ-45 connector to connect to a LAN, or a crossover
cable to connect to a PC equipped with an Ethernet card.
Your Ethernet Network Information
To connect the oscilloscope to the network, you must first obtain
information from your network administrator. For your convenience,
use the form on page G-- 15.
Make two photocopies of the form and send them to your network
administrator to fill in. If you require remote access to the oscilloscope for programming or e*Scope access, then have the network
administrator fill in section 1. If you require your oscilloscope to
print screen hard copies to a network printer, then have the network
administrator fill in sections 1 and 2. The administrator can then
return one copy to you and keep the other copy.
NOTE. If the DHCP/BOOTP server assigns a dynamic IP address,
then the value in the Instrument IP Address field may be different
