Learning the Front Panel Controls (Keys and Knobs)
The Infiniium S-Series oscilloscope front panel controls provide direct access to
the functions needed to perform the most common measurements. Knobs and
keys let you directly set vertical and horizontal parameters. You can see the
oscilloscope’s configuration at a glance.
The oscilloscope uses color consistently throughout the front panel and user
interface. For example, the color of the knob for channel 1 is the same color as the
waveform for channel 1. All configuration items and values related to channel 1 are
displayed in the same color.

mouse over or touch the horizontal position field and use the resulting controls
to set a particular horizontal position (time relative to the trigger at the
highlighted horizontal reference point).
The waveform display area splits into two regions. The top one is the main
timebase. The bottom is the zoomed timebase, which represents an expansion
of the acquired waveform data. A section of the waveform in the main timebase
window is highlighted to indicate the part shown in the zoomed timebase
window.
The horizontal scale and position controls now change how the waveform is
shown in the zoomed timebase window. The horizontal scale will change the
amount of magnification, while the position will change the part of the
waveform in the main window that is shown in the zoomed window.
• To turn off zoom, press or click again.
Avoid Overdriving Vertical Input Amplifiers
When zooming on a waveform with the oscilloscope running, be careful to keep the signal
within the screen vertically to avoid overdriving the vertical input amplifiers. Overdriving
causes waveform distortion and erroneous measurement results.
Setting the scale, position, and timebase reference point
To set scale, position, and timebase reference, use the Horizontal dialog box or set
up the zoomed timebase window.
To access the Horizontal dialog box, click the in the horizontal toolbar, or

Keysight Infiniium S-Series Oscilloscopes User’s Guide 37
2 Using the Oscilloscope
NOTE
Using an Analog Channel as Trigger
Any analog channel can be used as a trigger source. If you need a trigger but do not need all
analog channels, you can use an analog channel as a trigger without displaying it by turning
the analog channel display off.
Adjusting an analog channel’s vertical scale and offset
To adjust the vertical scale and offset, use the vertical scale and offset knobs,
vertical user interface controls, or Channel dialog box.
The vertical scale knob is the larger of the two knobs for a channel. Turn the knob
to make the waveform bigger (fewer volts per division) or smaller. You can also
mouse over or touch the vertical scale field and use the resulting controls to set an
exact value for the scaling.
If you are not using a particular analog channel, you can turn it off to simplify
the waveform display and increase the display update rate. Functions continue
to run on a channel source that is turned off. Data acquisition continues for a
channel if a function requires it.
The vertical offset knob is the smaller knob for a channel. Turn it to move the
waveform up or down.
You can drag the waveform or its ground reference indicator to the desired vertical
offset if the grid is in drag mode .
Choose Setup > Channel N... or click a channel number to open the Channel dialog
box, in which you can set the vertical scale, offset, skew, and labels. You can also
specify the characteristics of a probe, or perform a probe calibration.
For Keysight Technologies probes that are compatible with AutoProbe II interfaces,
the oscilloscope will automatically set these characteristics (except for skew) after
identifying the probe when it is connected to the channel input.
38 Keysight Infiniium S-Series Oscilloscopes User’s Guide
Setting Up Triggers
Use the trigger controls to set the conditions on which the oscilloscope will trigger
and acquire an input signal. You can set up a variety of trigger conditions. Edge
triggers and the parameters for edge triggering can be set up from the front panel.
Trigger configuration settings you make using the user interface are reflected in
the front panel Trigger status indicators, and will remain set unless you change
them or press [Default Setup].

2 Press [Slope] until the desired slope LED is lit.
You can have an edge trigger on a rising or falling edge, or both.
3 Press [Sweep] until the desired LED is lit (Trig’d or Auto).
When Trig’d is selected, the oscilloscope must find the trigger before saving and
displaying captured data.
When Auto is selected, if a trigger does not occur within a certain amount of
time, an acquisition is automatically saved and displayed. In Auto trigger mode,
you are able to see your signals while setting up the desired trigger.
4 Turn the Level knob to adjust the voltage level at which the oscilloscope will
trigger.
Use the Trigger dialog box to select any of the modes of triggering, the parameters
and conditions for each trigger mode, and advanced configuration items.

Making Measurements and Using Markers
Use the measurement controls to display and adjust markers, define a key to
perform automatic measurements or other quick actions, and make
measurements.
Using the Oscilloscope 2

Drag & drop measurement
icons showing most
commonly used measurements

measurement icons
Figure 18 Drag & Drop measurements
Keysight Infiniium S-Series Oscilloscopes User’s Guide 41
2 Using the Oscilloscope
Making a measurement on a waveform
To make a measurement, either drag a measurement icon to the waveform event
you want to measure, or click a measurement icon and use the resulting dialog box
to specify which source you want to measure.
For measurements on waveform features, such as those that involve waveform
edges, if you click the measurement icon and specify a source, the measurement
defaults to using the feature closest to the horizontal reference point. If you make
the measurement using drag & drop, the measurement uses the waveform feature
closest to the point where you drop the icon.
The most commonly used measurements are available in the drag & drop area.
Others are available from the Add Measurement dialog box (Measure/Mark > Add
Measurement...).
When you drag and drop a measurement icon on a waveform, the icon outline
changes color to match the color of each waveform it touches so you can easily
see which waveform will be measured.
For edge-sensitive measurements, a circled number appears in the waveform
marker color when you drop the measurement icon on a waveform. This number
shows exactly where the measurement is being made. It appears next to the
measurement readout in the Results pane. This feature helps you distinguish
measurement results from each other when you make multiple measurements on
the same waveform but at different waveform features.
Using quick measurements
You can define the [Multi Purpose] key to perform one of many quick actions, such
as loading a setup file, saving composite data or a measurement report to a file,
saving the screen image to a bitmap file, or performing automatic measurements.
The action taken when [Multi Purpose] is pressed (or Utilities > Multipurpose is
chosen) depends on the feature selected in the Customize Multipurpose dialog
box (Utilities > Customize Multipurpose...). The default feature is QuickMeas.
• To turn on the quick measurement display, press [Multi Purpose]. The 10 preset
measurements defined in the Quick Measurement configuration are enabled
and results appear on the screen for the first waveform source.
• To measure parameters for another waveform, press [Multi Purpose] until that
waveform is the one shown in the measurement readout. Continuing to press
[Multi Purpose] cycles through each of the waveforms available.
• To turn off the quick measurement display, cycle through all channels until the
measurements are turned off.
See the Infiniium oscilloscope application’s online help for information on how to
configure the quick measurement capability.
42 Keysight Infiniium S-Series Oscilloscopes User’s Guide
Using markers
Markers make it easier to make precise measurements because the marker
measurement readouts show exact voltage and time positions for the markers. The
measurements are based on actual waveform data from the acquisition system,
not on approximations based on the display position, so you can be sure the values
are highly accurate.
Using the marker and measurement controls, you can control multiple sets of
markers within the oscilloscope grid.
Both time and voltage differences between the markers are updated continuously
on the screen. By default, the markers track the source waveform. Voltage
measurements from the markers are the value of the waveform at the time set with
the marker arrow keys.
• To add a marker, press the [Markers] key or choose Measure/Mark > Add Markers...
or click the Markers button , then select the sources and mode. Notice the
drawing in the Description area of the dialog box.
• To select one of the markers, push the Position knob. Turn the knob to move
the marker. Push the knob again to select the next marker.
Using the Oscilloscope 2
• Marker 1 has a solid line pattern on the waveform display. It is associated with
the first available source on the display.
• You can drag a marker to quickly move to the position you want on the
waveform.
• You can use the front panel Position knob for fine adjustment, or use the Add
Markers dialog box to set the marker position precisely.
Controlling digital channels
If your oscilloscope is an MSO model, choose Setup > Digital Channels... to open the
Digital dialog box so you can set up controls for the digital channels.
To turn the digital channels on, click the Add Waveforms button and select the
check box next to the , or press [Digital].
