Frequency
Markers The signal generator provides up to 20 independent,
pre-settable markers, F0-F9 and M0-M9, that can be
used in the step sweep frequency mode for precise
frequency identification. Marker frequency accuracy
is the same as sweep frequency accuracy. The mark-
ers are visible on a CRT display.
The MG369XB generates two types of markers:
q
Video Marker–produces a pulse on a CRT
display at each marker frequency. The video
marker is either a +5V or a –5V pulse avail-
able at the rear panel
AUX I/O connector. The
marker’s pulse polarity is selectable from the
System Configuration menu, page 3-78
q Intensity Marker–produces an intensified
dot on a CRT display at each marker fre-
quency. They are obtained by a momentary
dwell in the sweep at each marker frequency.
Intensity markers are only available in the an-
alog sweep frequency mode at sweep times of
<1 second
