Basic Digital Operation

Using Waveform Markers

1.Remove any existing marker points (page 94).

2.In the Marker Utilities menu (page 92), press Set Markers.

3.Highlight the desired waveform segment.

In ARB formats there is only one file (AUTOGEN_WAVEFORM) and it is already highlighted.

4.Highlight the desired marker number: Press Marker 1 2 3 4

5.Set the first sample point in the range (in this example, 5): Press Set Marker On Range Of Points > First Mkr Point > 5 > Enter.

6.Set the last marker point in the range to a value less than the number of points in the waveform, and

greater than or equal to the first marker point (in this example, 25): Press Last Mkr Point > 25 > Enter.

7.Enter the number of sample points that you want skipped (in this example, 1): Press # Skipped Points > 1 > Enter.

8.Press Apply To Waveform > Return.

This causes the marker to occur on every other point (one sample point is skipped) within the marker point range, as shown below.

Viewing markers is described on page 93

One application of the skipped point feature is the creation of a clock signal as the auxiliary output.

3. Controlling Markers in a Waveform Sequence (Dual ARB Only)

In a waveform segment, an enabled marker point generates an auxiliary output signal that is routed to the rear panel event connector (described in “Rear Panel” on page 18) corresponding to that marker number. For a waveform sequence, you enable or disable markers on a segment- by- segment basis; this enables you to output markers for some segments in a sequence, but not for others. Unless you change the marker settings or cycle the power, the setting remains the same for the next loaded sequence.

As You Create a Waveform Sequence

After you select the waveform segments to create a waveform sequence, and before you name and save the sequence, you can enable or disable each segment’s markers independently. Enabling a marker that has no marker points (page 95) has no effect on the auxiliary outputs.

1. Select the waveform segments (Step 1 on page 85).
