Using Waveform Markers
Storing Waveform Segments to Non–volatile Memory
1. Press Mode > Dual ARB > Waveform Segments .
2. If necessary, press Load Store to Store.
3. Press Store All To NVWFM Memory .
Copies of all WFM1 waveform segment files have been stored in non–volatile memory as NVWFM
files. To store files individually, highlight the file and press
Store Segment To NVWFM Memory .
Loading Waveform Segments from Non–volatile Memory
1. Clear out the volatile memory and delete all WFM1 files: Power cycle the instrument.
2. Press Mode > Dual ARB > Waveform Segments .
3. If necessary, press Load Store to Load.
4. Press Load All From NVWFM Memory .
Copies of all NVWFM waveform segment files have been loaded into volatile memory as WFM1 files.

To load files individually, highlight the file and press Load Segment From NVWFM Memory .
Renaming a Waveform Segment
1. Press Mode > Dual ARB > Waveform Segments .
2. Highlight the desired file and press Rename Segment > Editing Keys > Clear Text .
3. Enter the desired file name and then press Enter .
Using Waveform Markers
The signal generator provides four waveform markers to mark specific points on a waveform segment.
When the signal generator encounters an enabled marker, an auxiliary output signal is routed to the
rear panel event connector (described in
Rear Panel ) that corresponds to the marker number. You
can use this auxiliary output signal to synchronize another instrument with the waveform, or as a
trigger signal to start a measurement at a given point on a waveform.
You can also configure markers to initiate ALC hold, or RF Blanking (which includes ALC hold).
Creating a waveform segment ( page 92 ) also creates a marker file that places a marker point on the
first sample point of the segment for markers one and two. When a waveform file is downloaded that
does not have a marker file associated with it, the signal generator creates a marker file without any
marker points. Factory–supplied segments have a marker point on the first sample for all four
markers.
The following procedures demonstrate how to use markers while working in the dual ARB player, but
the process is the same when working in any ARB format.
These procedures also discuss two types of points: a marker point and a sample point. A marker
point is a point at which a given marker is set on a waveform; you can set one or more marker
points for each marker. A sample point is one of the many points that compose a waveform.
