This entry shows that only marker 3 is enabled for this segment.

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.

Marker points on first sample point of waveform segment

Viewing markers is described on page 93

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.
