Using Waveform Markers

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
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.
There are three basic steps to using waveform markers:
"1. Clearing Marker Points from a Waveform Segment" on page 117
"2. Setting Marker Points in a Waveform Segment" on page 118
"3. Controlling Markers in a Waveform Sequence (Dual ARB Only)" on
page 121
