Basic Digital Operation

Using Waveform Markers

Select a segment

The Set Marker display

The display below shows the I and Q components of the waveform, and the marker points set in a factory-supplied segment.

Marker points on first sample point

These softkeys change the range of waveform sample points shown on the marker display.

Each press of the softkey changes the sample range by approximately a factor of two

1. Clearing Marker Points from a Waveform Segment

When you set marker points they do not replace points that already exist, but are set in addition to existing points. Because markers are cumulative, before you set points, view the segment (page 93) and remove any unwanted points. With all markers cleared, the level of the event output signal is 0V.

Clearing All Marker Points

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

2.Highlight the desired waveform segment.

In an ARB format, there is only one file (AUTOGEN_WAVEFORM) and it is already highlighted.

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