R&S FSMR MKR – Analyzer

LINK MKR1
AND DELTA1
With the softkey LINK MKR1 AND DELTA1 the delta marker1 can be linked to
marker1, so if the x-axis value of the marker1 is changed the delta marker1 will
follow on the same x-position. The link is default off, and can be switched on.
Example for setup:
•
PRESET
•
TRACE | MAX HOLD
•
TRACE | SELECT TRACE | 2 | AVERAGE
•
MKR (Switches marker1 on)
•
MARKER NORM DELTA | DELTA (Delta Marker 1 ON)
•
MKR-> | MKR->TRACE | 2
•
LINK MKR1 AND DELTA1
Now select the Marker1 (by switching MARKER1 from DELTA back to NORM)
and when changing the x-axis value (by knob wheel or UP/DOWN keys) the
delta marker1 will follow automatically.
The delta marker1 x-value can not be changed away from 0 as long as the link
functionality is active.

The CNT RESOL ... softkeys select the counter resolution. They are selection
switches, i.e. only one of the can be active at any one time.
The marker stop time, ie the frequency measurement time, depends on the
selected resolution.
IEC/IEEE-bus command:
CALC:MARK1:COUN:RES <value>
Measurement example:
The frequency of a CW signal is to be determined by means of the frequency
counter with a resolution of 10 Hz.
[ PRESET ] R&S FSMR is set to the default setting.
[ MARKER ] MARKER 1 is switched on and set to the maximum value
of the displayed spectrum.
[ SIGNAL
COUNT ] The frequency counter is switched on. R&S FSMR counts
the frequency of the signal at the marker position with a
resolution of 1 kHz. The counted frequency is indicated in
the marker info field.
[ NEXT ] Changes to the submenu for setting the counter resolution.
[ CNT RESOL
10 Hz ] The frequency counter resolution is increased to 10 Hz.
STEPSIZE
STANDARD
STEPSIZE
SWP POINTS
These softkeys control the knob increment/decrement of the marker position.
STEPSIZE STANDARD uses the grid resolution (span/625), STEPSIZE SWP
POINTS uses the available sweep points configured in the SWEEP menu.
IEC/IEEE-bus command:
CALC1:MARK:X:SSIZ STAN | POIN
