MARKER
DATA Control Use for [,,,.
The marker can be moved along the trace with the DATA knob 0 , and the frequency span can be changed
about the marker with DATA step @ and @ . Each step also sets center frequency equal to the marker
frequency.
Measurement and Readout Range
The measurement and readout range for marker zoom is the same as marker (UL) .
DATA Entry
Example
In wide frequency spans, it is often necessary to expand a portion of the frequency span about a specific signal in
order to resolve modulation sidebands or track frequency drift.
Moves the marker continuously along the trace. Rate dependent on speed
of rotation. The marker moves in display unit increments.
Changes the frequency span to the next value in the sequence and sets the
center frequency equal to the marker frequency.
Places the marker at the frequency entered. An out-of-range entry places
the marker at a graticule border.
