Marker Count Widen RES BW
Indicates that the current resolution bandwidth setting is too narrow to use
with the marker counter function. The marker counter function can be in
narrow resolution bandwidths (bandwidths that are less than 1
kHz)
with
the following procedure:
1. Place the marker on the desired signal.
2. Increase the resolution bandwidth to 1
kHz
and verify the marker is on
the signal peak.
3. If the marker in on the signal peak, the marker count function can be
used in either the 1
kHz
resolution bandwidth or the original narrow
resolution bandwidth setting. If the marker is not on the signal peak,
it should be moved to the signal peak and the marker counter function
should not be used with a resolution bandwidth setting of less than
1
kHz.
