Basic Digital Operation
Using Waveform Markers
Viewing a Marker Pulse
When a waveform plays (page 86), you can detect a set and enabled marker’s pulse at the rear panel
event connector that corresponds to that marker number. This example demonstrates how to view a
marker pulse generated by a waveform segment that has at least one marker point set (page 95). The
process is the same for a waveform sequence.
This example uses the factory-supplied segment, SINE_TEST_WFM in the Dual ARB Player.
Factory-supplied segments have a marker point on the first sample point for all four markers, as
shown.
1. Press
Mode > Dual ARB > Select Waveform, and highlight the desired segment (in this example,
SINE_TEST_WFM).
2. Press
ARB Off On to On.
3. Connect an oscilloscope input to the EVENT 1 connector, and trigger on the Event 1 signal.
When a marker is present, the oscilloscope displays a marker pulse, as shown in the following
example.
