MARKER
ZOOM
The MARKER ZOOM softkey expands the area around MARKER 1. With the
zoom function, more details of the spectrum can be seen. The desired display
range can be defined in an entry window.
The following sweep is stopped at the position of the reference marker. The
frequency of the signal is counted and the measured frequency becomes the
new center frequency. The zoomed display range is then configured and the
new settings are used by R&S FSMR for further measurements.
As long as switching to the new frequency display range has not yet taken
place, pressing the softkey will abort the procedure.
If MARKER 1 is not active when the softkey is pressed, it is automatically
activated and set to the highest peak in the window.
If an instrument setting is changed after selection of MARKER ZOOM , the
function is aborted.
The MARKER ZOOM softkey is only available in the frequency domain
(span
>
0).
IEC/IEEE-bus command:
CALC:MARK1:FUNC:ZOOM 1kHz
ALL MARKER
OFF
The ALL MARKER OFF softkey switches off all markers (reference and delta
markers). It also switches off all functions and displays associated with the
markers/delta markers.
IEC/IEEE-bus command:
CALC:MARK:AOFF
MARKER NEXT menu
MRK TRACE
The MKR TRACE softkey places the marker on a new trace. The trace is
selected via a data entry field. Only those traces can be selected which are
visible on the screen in the same window.
Example:
Three traces are presented on the screen. The marker is always on Trace 1 on
switching on.
[ MKR ->TRACE]
"2"<ENTER> The marker jumps to Trace 2 but remains on the previ-
ous frequency or time.
[ MKR ->TRACE]
"3"<ENTER> The marker jumps to Trace 3. '
