42 Keysight Infiniium 9000 Series Oscilloscopes User’s Guide
2 Using the Oscilloscope
• To turn on the quick measurement display, press the [Multi Purpose] key. 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 the [Multi Purpose] key until
that waveform is the one shown in the measurement readout. Continuing to
press the [Multi Purpose] key 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.
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 control two 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 open the Markers dialog box so you can select the type of marker mode you
want to use, press the [Markers] key.
• To turn on Marker 1 (X1), push the Select knob. Turn the knob to move the
marker. Push the knob again to select Marker 1 (Y1).
Marker 1 (X1 and Y1) has a solid line pattern on the waveform display. It is
associated with the first available source on the display.
• To turn on Marker 2 (X2), push the Select knob again.
Marker 2 has a dashed line pattern on the waveform display. It is associated
with the first available source on the display.
• In Track Measurements mode, the marker position cannot be changed.
Moving markers using the user interface
1 Turn on the markers by choosing Measure > Markers... and selecting a mode from
the Markers dialog box. You can also click the Markers button to either turn
on markers or bring up the Markers dialog box.
2 Drag one of the markers to the position you want on the waveform.
