This chapter describes the steps you take when using the oscilloscope for the first
time.
Inspect the Package Contents
• Inspect the shipping container for damage.
If your shipping container appears to be damaged, keep the shipping container
or cushioning material until you have inspected the contents of the shipment
for completeness and have checked the oscilloscope mechanically and
electrically.

1Getting Started
• Verify that you received the following items and any optional accessories you
may have ordered:
• InfiniiVision 6000 X-Series oscilloscope.
• Power cord (country of origin determines specific type).
The air intake and exhaust areas must be free from obstructions. Unrestricted air
flow is required for proper cooling. Always ensure that the air intake and exhaust
areas are free from obstructions.
The fan draws air in from the left side and bottom of the oscilloscope and pushes it
out behind the oscilloscope.
To po wer-on the
CAUTION
WARNING
oscilloscope
Getting Started1
When using the oscilloscope in a bench-top setting, provide at least 2" clearance
at the sides and 4" (100 mm) clearance above and behind the oscilloscope for
proper cooling.
Use only the power cord that came with the oscilloscope
The power cord provided is matched to the country of origin of the order.
1 Connect the power cord to the rear of the oscilloscope, then to a suitable AC
voltage source. Route the power cord so the oscilloscope's feet and legs do not
pinch the cord. Position the oscilloscope so that access to the power switch or
power cord is not restricted.
2 The oscilloscope automatically adjusts for input line voltages in the range 100
to 240 VAC. The line cord provided is matched to the country of origin.
Always use a grounded power cord. Do not defeat the power cord ground.
3 Press the power switch.
The power switch is located on the lower left corner of the front panel. The
oscilloscope will perform a self-test and will be operational in a few seconds.
Connect Probes to the Oscilloscope
1 Connect the oscilloscope probe to an oscilloscope channel BNC connector.
2 Connect the probe's retractable hook tip to the point of interest on the circuit or
device under test. Be sure to connect the probe ground lead to a ground point
on the circuit.
The maximum input voltage for the 50 Ω input impedance setting is ±5 V.
Input protection is enabled in 50 Ω mode and the 50 Ω load will disconnect if greater
than 5 Vrms is detected. However the inputs could still be damaged, depending on the
time constant of the signal. The 50 Ω input protection functions only when the
oscilloscope is powered on.
The maximum input voltage for the 1 MΩ input impedance setting is 30 Vrms or
±40 Vmax (DC+Vpeak)
Probing technology allows for testing of higher voltages; the included N2894A 10:1
probe supports 300 Vrms or ±400 Vmax (DC+Vpeak). No transient overvoltage allowed.
When measuring voltages over 30 V, use a 10:1 probe.
Do not float the oscilloscope chassis
Defeating the ground connection and "floating" the oscilloscope chassis will probably
result in inaccurate measurements and may also cause equipment damage. The probe
ground lead is connected to the oscilloscope chassis and the ground wire in the power
cord. If you need to measure between two live points, use a differential probe with
sufficient dynamic range.
Do not negate the protective action of the ground connection to the oscilloscope. The
oscilloscope must remain grounded through its power cord. Defeating the ground
creates an electric shock hazard.
Input a Waveform
The first signal to input to the oscilloscope is the Demo 2, Probe Comp signal. This
signal is used for compensating probes.
1 Connect an oscilloscope probe from channel 1 to the Demo 2 (Probe Comp)
terminal on the front panel.
2 Connect the probe's ground lead to the ground terminal (next to the Demo 2
terminal).
Recall the Default Oscilloscope Setup
To recall the default oscilloscope setup:
1 Press [Default Setup].
The default setup restores the oscilloscope's default settings. This places the
oscilloscope in a known operating condition. The major default settings are:
Table 2 Default Configuration Settings
HorizontalNormal mode, 100 µs/div scale, 0 s delay, center time reference.
Vertical (Analog)Channel 1 on, 5 V/div scale, DC coupling, 0 V position, 1 MΩ impedance.
Getting Started1
TriggerEdge trigger, Auto trigger mode, 0 V level, channel 1 source, DC coupling, rising
OtherAcquire mode normal, [Run/Stop] to Run, cursors and measurements off.
LabelsAll custom labels that you have created in the Label Library are preserved (not
erased), but all channel labels will be set to their original names.
In the Save/Recall Menu, there are also options for restoring the complete factory
settings (see "Recalling Default Setups" on page 369) or performing a secure
erase (see "Performing a Secure Erase" on page 370).
Use Autoscale
Use [Auto Scale] to automatically configure the oscilloscope to best display the
input signals.
You should see a waveform on the oscilloscope's display similar to this:
2 If you want to return to the oscilloscope settings that existed before, press Undo
Autoscale.
3 If you want to enable "fast debug" autoscaling, change the channels
autoscaled, or preserve the acquisition mode during autoscale, press Fast
Debug, Channels, or Acq Mode.
These are the same softkeys that appear in the Autoscale Preferences Menu.
See "To set Autoscale preferences" on page 386.
If you see the waveform, but the square wave is not shaped correctly as shown
above, perform the procedure "Compensate Passive Probes" on page 39.
If you do not see the waveform, make sure the probe is connected securely to the
front panel channel input BNC and to the left side, Demo 2, Probe Comp terminal.
Auto Scale analyzes any waveforms present at each channel and at the external
trigger input. This includes the digital channels, if connected.
Auto Scale finds, turns on, and scales any channel with a repetitive waveform that
has a frequency of at least 25 Hz, a duty cycle greater than 0.5%, and an
amplitude of at least 10 mV peak-to-peak. Any channels where no signal is found
are turned off.
The trigger source is selected by looking for the first valid waveform starting with
external trigger, then continuing with the lowest number analog channel up to the
highest number analog channel, and finally (if digital probes are connected) the
highest number digital channel.
During Autoscale, the delay is set to 0.0 seconds, the horizontal time/div (sweep
speed) setting is a function of the input signal (about 2 periods of the triggered
signal on the screen), and the triggering mode is set to Edge.
Compensate Passive Probes
Each oscilloscope passive probe must be compensated to match the input
characteristics of the oscilloscope channel to which it is connected. A poorly
compensated probe can introduce significant measurement errors.
1 Input the Probe Comp signal (see "Input a Waveform" on page 36).
2 Press [Default Setup] to recall the default oscilloscope setup (see "Recall the
Default Oscilloscope Setup" on page 37).
3 Press [Auto Scale] to automatically configure the oscilloscope for the Probe
Comp signal (see "Use Autoscale" on page 37).
4 Press the channel key to which the probe is connected ([1], [2], etc.).
5 In the Channel Menu, press Probe.
6 In the Channel Probe Menu, press Probe Check; then, follow the instructions
on-screen.
Getting Started1
If necessary, use a nonmetallic tool (supplied with the probe) to adjust the
trimmer capacitor on the probe for the flattest pulse possible.
On N2894A probes, the trimmer capacitor is located on the probe BNC
connector.
Softkey specifically refers to the six keys that are directly below the display. The
legend for these keys is directly above them, on the display. Their functions
change as you navigate through the oscilloscope's menus.
For the following figure, refer to the numbered descriptions in the table that
follows.

adjust waveform intensity.
You can vary the intensity control to bring out signal detail, much like an
analog oscilloscope.
Digital channel waveform intensity is not adjustable.
More details about using the Intensity control to view signal detail are on
"To adjust waveform intensity" on page 161.
1Getting Started
4.Entry knobThe Entry knob is used to select items from menus and to change values.
The function of the Entry knob changes based upon the current menu and
softkey selections.
Note that the curved arrow symbol above the entry knob illuminates
whenever the entry knob can be used to select a value. Also, note that
when the Entry knob symbol appears on a softkey, you can use the
Entry knob, to select values.
Often, rotating the Entry knob is enough to make a selection. Sometimes,
you can push the Entry knob to enable or disable a selection. Pushing the
Entry knob also makes popup menus disappear.

Attach oscilloscope probes or BNC cables to these BNC connectors.
With the InfiniiVision 6000 X-Series oscilloscopes, you can set the input
impedance of the analog channels to either 50 Ω or 1 MΩ. See "To
specify channel input impedance" on page 89.
The InfiniiVision 6000 X-Series oscilloscopes also provide the AutoProbe
interface. The AutoProbe interface uses a series of contacts directly below
the channel's BNC connector to transfer information between the
oscilloscope and the probe. When you connect a compatible probe to the
oscilloscope, the AutoProbe interface determines the type of probe and
sets the oscilloscope's parameters (units, offset, attenuation, coupling, and
impedance) accordingly.

19.USB Host portsThese ports are for connecting a USB mass storage device, printer, mouse,
or keyboard to the oscilloscope.
Connect a USB compliant mass storage device (flash drive, disk drive, etc.)
to save or recall oscilloscope setup files and reference waveforms or to
save data and screen images. See Chapter 22, “Save/Email/Recall
(Setups, Screens, Data),” starting on page 357.
To print, connect a USB compliant printer. For more information about
printing see Chapter 23, “Print (Screens),” starting on page 371.
You can also use the USB port to update the oscilloscope's system
software when updates are available.
You do not need to take special precautions before removing the USB mass
storage device from the oscilloscope (you do not need to "eject" it). Simply
unplug the USB mass storage device from the oscilloscope when the file
operation is complete.
CAUTION:Do not connect a host computer to the oscilloscope's USB
host port. Use the device port. A host computer sees the oscilloscope as a
device, so connect the host computer to the oscilloscope's device port (on
the rear panel). See "I/O Interface Settings" on page 377.
There is a third USB host port on the back panel.

the localization option is chosen at time of purchase.
To install a front panel overlay:
1 Gently pull on the front panel knobs to remove them.
• Pinch — used to zoom in on a waveform of interest. A horizontal pinch
adjusts the oscilloscope's time/div and delay settings at once — for "off
center zooming", this is more efficient than using knobs. A vertical pinch
adjusts a waveform's V/div and offset settings at once.
To select waveforms, tap them. The waveform closest horizontally to the tap
location is selected. The selected waveform is indicated by the ground
marker with the filled background (channel 1 in the following example).
Use a USB Mouse and/or Keyboard for Touchscreen Controls
Connecting a USB mouse gives you a mouse pointer on the display. Mouse clicks
and drags behave the same as screen touches and finger drags.
If you connect a USB keyboard, you can use it to enter values in alpha-numeric
keypad dialogs.
Learn the Voice Controls
Voice control is a valuable feature when browsing signals in your device under test
and using your hands to hold down probes. The set of voice commands is limited
so they are easy to remember.
On the upper right corner of the display is an icon that describes the state of voice
recognition:
• means voice recognition is not running at all.
Getting Started1
• means voice recognition is running but it is only listening for the wakeup
command.
• means voice recognition is listening for commands.
To enable voice recognition, tap the icon and (in the Audio Menu) press the Voice Recognition softkey.
The initial screen shows the list of commands and includes a few brief
explanations. There is also a smaller help screen that simply lists the commands.
The best way to recall the list of voice commands is to say the command "Help".
Most equipment noise will not bother recognition but other people speaking will.
Use a USB headset if other people are speaking nearby.
It is best to speak at a normal speed. Speaking slowly or with long pauses will
make recognition worse just like speaking too quickly.
The voice recognition uses Speaker Adaption. This is reset each time a different
person speaks, so it is best if only one person speaks to the oscilloscope.

The Horizontal Menu lets you select the time mode (Normal, XY, or Roll), enable
Zoom, set the time base fine control (vernier), and specify the time reference.
The current sample rate is displayed in the right-side information area.
• Use the touchscreen pinch gesture (see "Pinch, Flick, or Drag to Scale,
Position, and Change Offset" on page 52).
• Use the touchscreen controls to open a horizontal scale/delay dialog (see
"Access the Horizontal Menu and Open the Scale/Delay Dialog" on page 61).
• Turn the large horizontal scale (sweep speed) knob marked to
change the horizontal time/div setting.
Notice how the time/div information in the status line changes.
The ∇ symbol at the top of the display indicates the time reference point.
The horizontal scale knob works (in the Normal time mode) while acquisitions are
running or when they are stopped. When running, adjusting the horizontal scale
knob changes the sample rate. When stopped, adjusting the horizontal scale knob
lets you zoom into acquired data. See "Panning and Zooming Single or Stopped
Acquisitions" on page 72.
Note that the horizontal scale knob has a different purpose in the Zoom display.
See "To display the zoomed time base" on page 77.
To adjust the horizontal delay (position)
You can:
• Use the touchscreen flick and drag gestures (see "Pinch, Flick, or Drag to
Scale, Position, and Change Offset" on page 52).
• Use the touchscreen controls to open a horizontal scale/delay dialog (see
"Access the Horizontal Menu and Open the Scale/Delay Dialog" on page 61).
• Turn the horizontal delay (position) knob ().
The trigger point moves horizontally, pausing at 0.00 s (mimicking a
mechanical detent), and the delay value is displayed in the status line.
Changing the delay time moves the trigger point (solid inverted triangle)
horizontally and indicates how far it is from the time reference point (hollow
inverted triangle ∇). These reference points are indicated along the top of the
display grid.
Figure 2 shows the trigger point with the delay time set to 200 µs. The delay time
number tells you how far the time reference point is located from the trigger point.
When delay time is set to zero, the delay time indicator overlays the time reference
indicator.
All events displayed left of the trigger point happened before the trigger occurred.
These events are called pre-trigger information, and they show events that led up
to the trigger point.
Everything to the right of the trigger point is called post-trigger information. The
amount of delay range (pre-trigger and post-trigger information) available
depends on the time/div selected and memory depth.
The horizontal position knob works (in the Normal time mode) while acquisitions
are running or when they are stopped. When running, adjusting the horizontal
scale knob changes the sample rate. When stopped, adjusting the horizontal scale
knob lets you zoom into acquired data. See "Panning and Zooming Single or
Stopped Acquisitions" on page 72.
Note that the horizontal position knob has a different purpose in the Zoom display.
See "To display the zoomed time base" on page 77.
Panning and Zooming Single or Stopped Acquisitions
When the oscilloscope is stopped, use the touchscreen pinch, flick, and drag
gestures or use the horizontal scale and position knobs to pan and zoom your
waveform. The stopped display may contain several acquisitions worth of
information, but only the last acquisition is available for pan and zoom.
The ability to pan (move horizontally) and scale (expand or compress horizontally)
an acquired waveform is important because of the additional insight it can reveal
about the captured waveform. This additional insight is often gained from seeing
the waveform at different levels of abstraction. You may want to view both the big
picture and the specific little picture details.
The ability to examine waveform detail after the waveform has been acquired is a
benefit generally associated with digital oscilloscopes. Often this is simply the
ability to freeze the display for the purpose of measuring with cursors or printing
the screen. Some digital oscilloscopes go one step further by including the ability
to further examine the signal details after acquiring them by panning through the
waveform and changing the horizontal scale.
There is no limit imposed on the scaling ratio between the time/div used to
acquire the data and the time/div used to view the data. There is, however, a
useful limit. This useful limit is somewhat a function of the signal you are
analyzing.
Zooming into stopped acquisitions
The screen will still contain a relatively good display if you zoom-in horizontally by a factor of
1000 and zoom-in vertically by a factor of 10 to display the information from where it was
acquired. Remember that you can only make automatic measurements on displayed data.
To change the horizontal time mode (Normal, XY, or Roll)
1 Press [Horiz].
2 In the Horizontal Menu, press Time Mode; then, select:
• Normal — the normal viewing mode for the oscilloscope.
In the Normal time mode, signal events occurring before the trigger are
plotted to the left of the trigger point (▼) and signal events after the trigger
plotted to the right of the trigger point.
• XY — XY mode changes the display from a volts-versus-time display to a
volts-versus-volts display. The time base is turned off. Channel 1 amplitude
is plotted on the X-axis and Channel 2 amplitude is plotted on the Y-axis.
You can use XY mode to compare frequency and phase relationships
between two signals. XY mode can also be used with transducers to display
strain versus displacement, flow versus pressure, volts versus current, or
voltage versus frequency.
Use the cursors to make measurements on XY mode waveforms.
For more information about using XY mode for measurements, refer to "XY
Time Mode" on page 74.
• Roll — causes the waveform to move slowly across the screen from right to
left. It only operates on time base settings of 50 ms/div and slower. If the
current time base setting is faster than the 50 ms/div limit, it will be set to
50 ms/div when Roll mode is entered.
ExampleThis exercise shows a common use of the XY display mode by measuring the
In Roll mode there is no trigger. The fixed reference point on the screen is the
right edge of the screen and refers to the current moment in time. Events
that have occurred are scrolled to the left of the reference point. Since there
is no trigger, no pre-trigger information is available.
If you would like to pause the display in Roll mode press the [Single] key. To
clear the display and restart an acquisition in Roll mode, press the [Single]
key again.
Use Roll mode on low-frequency waveforms to yield a display much like a
strip chart recorder. It allows the waveform to roll across the display.
The XY time mode converts the oscilloscope from a volts-versus-time display to a
volts-versus-volts display using two input channels. Channel 1 is the X-axis input,
channel 2 is the Y-axis input. You can use various transducers so the display could
show strain versus displacement, flow versus pressure, volts versus current, or
voltage versus frequency.
phase difference between two signals of the same frequency with the Lissajous
method.
1 Connect a sine wave signal to channel 1, and a sine wave signal of the same
frequency but out of phase to channel 2.
2 Press the [Auto Scale] key, press the [Horiz] key; then, press Time Mode and select
"XY".
3 Center the signal on the display with the channel 1 and 2 position ( ) knobs.
Use the channel 1 and 2 volts/div knobs and the channel 1 and 2 Fine softkeys
to expand the signal for convenient viewing.
The phase difference angle (θ) can be calculated using the following formula
(assuming the amplitude is the same on both channels):
Figure 4 Phase difference measurements, automatic and using cursors
7 Calculate the phase difference using the formula below.
For example, if the first ΔY value is 2.297 and the second ΔY value is 1.319:
Z-Axis Input in XY Display Mode (Blanking)
When you select the XY display mode, the time base is turned off. Channel 1 is the X-axis
input, channel 2 is the Y-axis input, and the EXT TRIG IN is the Z-axis input. If you only want to
see portions of the Y versus X display, use the Z-axis input. Z-axis turns the trace on and off
(analog oscilloscopes called this Z-axis blanking because it turned the beam on and off).
When Z is low (<1.4 V), Y versus X is displayed; when Z is high (>1.4 V), the trace is turned off.

Zoom, formerly called Delayed sweep mode, is a horizontally expanded version of
the normal display. When Zoom is selected, the display divides in half. The top
half of the display shows the normal time/div window and the bottom half
displays a faster Zoom time/div window.
The Zoom window is a magnified portion of the normal time/div window. You can
use Zoom to locate and horizontally expand part of the normal window for a more
detailed (higher-resolution) analysis of signals.
To turn on (or off ) Zoom:
1 Press the zoom key (or press the [Horiz] key and then the Zoom softkey).
The area of the normal display that is expanded is outlined with a box and the rest
of the normal display is ghosted. The box shows the portion of the normal sweep
that is expanded in the lower half.
To change the time/div for the Zoom window, turn the horizontal scale (sweep
speed) knob. As you turn the knob, the zoomed window time/div is highlighted in
the status line above the waveform display area. The Horizontal scale (sweep
speed) knob controls the size of the box.
The Horizontal position (delay time) knob sets the left-to-right position of the
zoom window. The delay value, which is the time displayed relative to the trigger
point) is momentarily displayed in the upper-right portion of the display when the
delay time () knob is turned.
Negative delay values indicate you're looking at a portion of the waveform before
the trigger event, and positive values indicate you're looking at the waveform after
the trigger event.
To change the time/div of the normal window, turn off Zoom; then, turn the
horizontal scale (sweep speed) knob.
For information about using zoom mode for measurements, refer to "To isolate a
pulse for Top measurement" on page 260 and "To isolate an event for frequency
measurement" on page 267.
To change the horizontal scale knob's coarse/fine adjustment
setting
1 Push the horizontal scale knob (or press [Horiz] > Fine) to toggle between fine
and coarse adjustment of the horizontal scale.
When Fine is enabled, turning the horizontal scale knob changes the time/div
(displayed in the status line at the top of the display) in smaller increments. The
time/div remains fully calibrated when Fine is on.
When Fine is turned off, the Horizontal scale knob changes the time/div setting in
a 1-2-5 step sequence.
To position the time reference (left, center, right, custom)
Time reference is the reference point on the display for delay time (horizontal
position).
1 Press [Horiz].
2 In the Horizontal Menu, press Time Ref; then, select:
• Left — the time reference is set to one major division from the left edge of the
display.
• Center — the time reference is set to the center of the display.
• Right — the time reference is set to one major division from the right edge of
the display.
• Custom Location — lets you place the time reference location at a percent of
the graticule width (where 0% is the left edge and 100% is the right edge).
A small hollow triangle (∇) at the top of the display grid marks the position of the
time reference. When delay time is set to zero, the trigger point indicator (▼)
overlays the time reference indicator.
The time reference position sets the initial position of the trigger event within
acquisition memory and on the display, with delay set to 0.
Turning the Horizontal scale (sweep speed) knob expands or contracts the
waveform about the time reference point (∇). See "To adjust the horizontal
(time/div) scale" on page 70.
Turning the Horizontal position () knob in Normal mode (not Zoom) moves the
trigger point indicator (▼) to the left or right of the time reference point (∇). See
"To adjust the horizontal delay (position)" on page 71.
Searching for Events
You can use the [Search] key and menu to search for Edge, Pulse Width, Rise/Fall
Time, Runt, Frequency Peaks, and Serial events on the analog channels.
Setting up searches (see "To set up searches" on page 80) is similar to setting up
triggers. In fact, except for Frequency Peaks and Serial events, you can copy
search setups to trigger setups and vice-versa (see "To copy search setups" on
page 80).
Searches are different than triggers in that they use the measurement threshold
settings instead of trigger levels.
Found search events are marked with white triangles at the top of the graticule,
and the number of events found is displayed in the menu line just above the
softkey labels.
1 Press [Search].
2 In the Search Menu, press Search; then, turn the Entry knob to select the search
type.
3 Use the remaining softkeys to set up the selected search type.
In most cases, setting up searches is similar to setting up triggers:
• For setting up Edge searches, see "Edge Trigger" on page 180.
• For setting up Pulse Width searches, see "Pulse Width Trigger" on
page 184.
• For setting up Rise/Fall Time searches, see "Rise/Fall Time Trigger" on

• For setting up Runt searches, see "Runt Trigger" on page 194.
• For setting up Frequency Peak searches, see "Searching for FFT Peaks" on
page 110.
• For setting up Serial searches, see "Serial Trigger" on page 211 and
"Searching Lister Data" on page 159.
Remember that searches use the measurement threshold settings instead of
trigger levels. Use the Thresholds softkey in the Search Menu to access the
Measurement Threshold Menu. See "Measurement Thresholds" on page 279.
To copy search setups
Except for Frequency Peak and Serial event search setups, you can copy search
setups to trigger setups and vice-versa.

The ground level of the signal for each displayed analog channel is identified by
the position of the icon at the far-left side of the display.
To turn waveforms on or off (channel or math)
You can:
• Use the touchscreen controls to turn channels on or off (see "Turn Channels
On/Off and Open Scale/Offset Dialogs" on page 61).
• Press an analog channel key turn the channel on or off (and to display the
channel's menu).
You must be viewing the menu for a channel before you can turn it off. For example, if channel
1 and channel 2 are turned on and the menu for channel 2 is being displayed, to turn channel
1 off, press [1] to display the channel 1 menu; then, press [1] again to turn channel 1 off.
To adjust the vertical scale
You can:
• Use the touchscreen pinch gesture (see "Pinch, Flick, or Drag to Scale,
Position, and Change Offset" on page 52).
• Use the touchscreen controls to open a vertical scale/offset dialog (see "Turn
Channels On/Off and Open Scale/Offset Dialogs" on page 61).
• Turn the large knob above the channel key marked to set the vertical
scale (volts/division) for the channel.
The vertical scale knob changes the analog channel scale in a 1-2-5 step
sequence (with a 1:1 probe attached) unless fine adjustment is enabled (see "To
change the vertical scale knob's coarse/fine adjustment setting" on page 90).
Vertical Controls3
The analog channel Volts/Div value is displayed in the status line.
The default mode for expanding the signal when you turn the volts/division knob
is vertical expansion about the ground level of the channel; however, you can
change this to expand about the center of the display. See "To choose "expand
about" center or ground" on page 383.
To adjust the vertical position
You can:
• Use the touchscreen pinch and drag gestures (see "Pinch, Flick, or Drag to
Scale, Position, and Change Offset" on page 52).
• Use the touchscreen controls to open a vertical scale/offset dialog (see "Turn
Channels On/Off and Open Scale/Offset Dialogs" on page 61).
• Turn the small vertical position knob ( ) to move the channel's waveform up or
down on the display.
The offset voltage value represents the voltage difference between the vertical
center of the display and the ground level () icon. It also represents the voltage
at the vertical center of the display if vertical expansion is set to expand about
ground (see "To choose "expand about" center or ground" on page 383).
To specify channel coupling
Coupling changes the channel's input coupling to either AC (alternating current)
or DC (direct current).
If the channel is DC coupled, you can quickly measure the DC component of the signal by
simply noting its distance from the ground symbol.
If the channel is AC coupled, the DC component of the signal is removed, allowing you to use
greater sensitivity to display the AC component of the signal.
1 Press the desired channel key.
2 In the Channel Menu, press the Coupling softkey to select the input channel
coupling:
• DC — DC coupling is useful for viewing waveforms as low as 0 Hz that do not
have large DC offsets.
• AC — AC coupling is useful for viewing waveforms with large DC offsets.
When AC coupling is chosen, you cannot select 50Ω mode. This is done to
prevent damage to the oscilloscope.
AC coupling places a 10 Hz high-pass filter in series with the input waveform
that removes any DC offset voltage from the waveform.
Note that Channel Coupling is independent of Trigger Coupling. To change trigger
coupling see "To select the trigger coupling" on page 217.
When you connect an AutoProbe, self-sensing probe, or a compatible InfiniiMax probe, the
oscilloscope automatically configures the analog input channels to the correct impedance.
1 Press the desired channel key.
2 In the Channel Menu, press Imped (impedance); then, select either:
• 50 Ohm — matches 50 ohm cables commonly used in making high frequency
measurements, and 50 ohm active probes.
When 50 Ohm input impedance is selected, it is displayed with the channel
information on-screen.
When AC coupling is selected (see "To specify channel coupling" on
page 88) or excessive voltage is applied to the input, the oscilloscope
automatically switches to 1M Ohm mode to prevent possible damage.
• 1M Ohm — is for use with many passive probes and for general-purpose
measurements. The higher impedance minimizes the loading effect of the
oscilloscope on the device under test.
Vertical Controls3
This impedance matching gives you the most accurate measurements because
reflections are minimized along the signal path.

5989-6162EN), available at www.keysight.com.
To specify bandwidth limiting
1 Press the desired channel key.
2 In the Channel Menu, press the BW Limit softkey to specify the channel's
bandwidth limit or to turn off the bandwidth limit.
For waveforms with frequencies below the bandwidth limit, turning the bandwidth
limit on removes unwanted high frequency noise from the waveform.
The bandwidth limit also limits the trigger signal path of any channel that has BW
Limit turned on.
The limits that can be selected depend on the bandwidth of oscilloscope, the
channel's input impedance setting, and the channel's V/div setting:

To change the vertical scale knob's coarse/fine adjustment setting
1 Push the channel's vertical scale knob (or press the channel key and then the
Fine softkey in the Channel Menu) to toggle between fine and coarse
adjustment of the vertical scale.
You can also do this using the touchscreen. See "Turn Channels On/Off and
Open Scale/Offset Dialogs" on page 61.
When Fine adjustment is selected, you can change the channel's vertical
sensitivity in smaller increments. The channel sensitivity remains fully calibrated
when Fine is on.
The vertical scale value is displayed in the status line at the top of the display.
When Fine is turned off, turning the volts/division knob changes the channel
sensitivity in a 1-2-5 step sequence.
1 Press the desired channel key.
2 In the Channel Menu, press the Invert softkey to invert the selected channel.
When Invert is selected, the voltage values of the displayed waveform are inverted.
Invert affects how a channel is displayed. However, when using basic triggers, the
oscilloscope attempts to maintain the same trigger point by changing trigger
settings.
Inverting a channel also changes the result of any math function selected in the
Waveform Math Menu or any measurement.
Setting Analog Channel Probe Options
1 Press the probe's associated channel key.
2 In the Channel Menu, press the Probe softkey to display the Channel Probe
Menu.
This menu lets you select additional probe parameters such as attenuation
factor and units of measurement for the connected probe.
Vertical Controls3
The Channel Probe Menu changes depending on the type of probe connected.
For passive probes, the Probe Check softkey appears; it guides you through the
process of compensating probes.
For some active probes (such as InfiniiMax probes), the oscilloscope can
accurately calibrate its analog channels for the probe. When you connect a
probe that can be calibrated, the Calibrate Probe softkey appears (and the probe
attenuation softkey may change). See "To calibrate a probe" on page 93.
See Also• "To specify the channel units" on page 92
1 Press the probe's associated channel key.
2 In the Channel Menu, press Probe.
3 In the Channel Probe Menu, press Units; then, select:
• Volts — for a voltage probe.
• Amps — for a current probe.
Channel sensitivity, trigger level, measurement results, and math functions will
reflect the measurement units you have selected.
This is set automatically if the oscilloscope can identify the connected probe. See
Analog channel inputs (see page 47).
The probe attenuation factor must be set properly for accurate measurement
results.
If you connect a probe that is not automatically identified by the oscilloscope, you
can manually set the attenuation factor as follows:
1 Press the channel key.
2 Press the Probe softkey until you have selected how you want to specify the
attenuation factor, choosing either Ratio or Decibels.
3 Turn the Entry knob to set the attenuation factor for the connected probe.
When measuring voltage values, the attenuation factor can be set from 0.1:1 to
10000:1 in a 1-2-5 sequence.
When measuring current values with a current probe, the attenuation factor can
be set from 10 V/A to 0.0001 V/A.
When specifying the attenuation factor in decibels, you can select values from
-20 dB to 80 dB.
If Amps is chosen as the units and a manual attenuation factor is chosen, then the
units as well as the attenuation factor are displayed above the Probe softkey.
When measuring time intervals in the nanoseconds (ns) range, small differences in
cable length can affect the measurement. Use Skew to remove cable-delay errors
between any two channels.
1 Probe the same point with both probes.
2 Press one of the probes associated channel key.
3 In the Channel Menu, press Probe.
4 In the Channel Probe Menu, press Skew; then, select the desired skew value.
Each analog channel can be adjusted ±100 ns in 10 ps increments for a total of
200 ns difference.
The skew setting is not affected by pressing [Default Setup] or [Auto Scale].
Vertical Controls3
To calibrate a probe
The Calibrate Probe softkey guides you through the process of calibrating probes.
For certain active probes, such as InfiniiMax probes, the oscilloscope can
accurately calibrate its analog channels for the probe. When you connect a probe
that can be calibrated, the Calibrate Probe softkey in the Channel Probe Menu
becomes active.
To calibrate one of these probes:
1 First, plug your probe into one of the oscilloscope channels.
This could be, for example, an InfiniiMax probe amplifier/probe head with
attenuators attached.
2 Connect the probe to the left side, Demo 2, Probe Comp terminal, and the
When calibrating a differential probe, connect the positive lead to the Probe Comp terminal
and the negative lead to the ground terminal. You may need to connect an alligator clip to the
ground lug to allow a differential probe to span between the Probe Comp test point and
ground. A good ground connection ensures the most accurate probe calibration.
3 Press the Channel on/off key to turn the channel on (if the channel is off).
4 In the Channel Menu, press the Probe softkey.
5 In the Channel Probe Menu, the second softkey from the left is for specifying
your probe head (and attenuation). Repeatedly press this softkey until the
probe head selection matches the attenuator you are using.
The choices are:
• 10:1 single-ended browser (no attenuator).
• 10:1 differential browser (no attenuator).
• 10:1 (+6 dB Atten) single-ended browser.
• 10:1 (+6 dB Atten) differential browser.
• 10:1 (+12 dB Atten) single-ended browser.
• 10:1 (+12 dB Atten) differential browser.
• 10:1 (+20 dB Atten) single-ended browser.
• 10:1 (+20 dB Atten) differential browser.
6 Press the Calibrate Probe softkey and follow the instructions on the display.

3 Use the Operator softkey to select an operator, transform, filter, or visualization.
For more information on the operators, see:
• "Math Operators" on page 98
• "Math Transforms" on page 100
• "Math Filters" on page 119
• "Math Visualizations" on page 122
4 Use the Source 1 softkey to select the analog channel, lower math function, or
reference waveform on which to perform math. You can rotate the Entry knob or
repetitively press the Source 1 softkey to make your selection.
Higher math functions can operate on lower math functions. For example, if
Math 1 is set up as a subtract operation between channels 1 and 2, the Math 2
function could be set up as a FFT operation on the Math 1 function. These are
called cascaded math functions.
To cascade math functions, select the lower math function using the Source 1
softkey.
When cascading math functions, to get the most accurate results, be sure to vertically scale
lower math functions so that their waveforms take up the full screen without being clipped.
5 If you selected an arithmetic operator for the math function, use the Source 2
softkey to select the second source for the arithmetic operation.
6 To re-size and re-position the math waveform, see "To adjust the math
waveform scale and offset" on page 97.
Math Operating Hints
If the analog channel or math function is clipped (not fully displayed on screen) the resulting
displayed math function will also be clipped.
Once the function is displayed, the analog channel(s) may be turned off for better viewing of
the math waveform.
The vertical scaling and offset of each math function can be adjusted for ease of viewing and
measurement considerations.
The math function waveform can be measured using [Cursors] and/or [Meas].
1 Make sure the multiplexed scale and position knobs above and below the [Math]
key are selected for the math waveform.
If the arrow to the left of the [Math] key is not illuminated, press the key.
2 Use the multiplexed scale and position knobs above and below the [Math] key to
re-size and re-position the math waveform.
Math Scale and Offset are Set Automatically
Any time the currently displayed math function definition is changed, the function is
automatically scaled for optimum vertical scale and offset. If you manually set scale and offset
for a function, select a new function, then select the original function, the original function will
be automatically rescaled.

Math Waveforms4
Units for Math Waveforms
Units for each input channel can be set to Volts or Amps using the Units softkey in
the channel's Probe Menu. Units for math function waveforms are:
* When the FFT source is channel 1, 2, 3 or 4, FFT units will be displayed in dBV when channel units
is set to Volts and channel impedance is set to 1 MΩ. FFT units will be displayed in dBm when
channel units is set to Volts and channel impedance is set to 50Ω. FFT units will be displayed as dB
for all other FFT sources or when a source channel's units has been set to Amps.
A scale unit of U (undefined) will be displayed for math functions when two source
channels are used and they are set to dissimilar units and the combination of units
cannot be resolved.
Math Operators
Math operators perform arithmetic operations (like add, subtract, or multiply) on
analog input channels.
When you select add or subtract, the Source 1 and Source 2 values are added or
subtracted point by point, and the result is displayed.
You can use subtract to make a differential measurement or to compare two
waveforms.
If your waveforms' DC offsets are larger than the dynamic range of the
oscilloscope's input channels you will need to use a differential probe instead.

Multiply or Divide
When you select the multiply or divide math function, the Source 1 and Source 2
values are multiplied or divided point by point, and the result is displayed.
The divide by zero case places holes (that is, zero values) in the output waveform.
Multiply is useful for seeing power relationships when one of the channels is
proportional to the current.

Math Transforms
Math transforms perform a transform function (like differentiate, integrate, FFT, or
square root) on an analog input channel or on the result of an arithmetic
operation.
