MKR TRACE
The MKR TRACE softkey sets the active marker to a new trace. If only one
trace is available on the screen, the softkey does not appear. If several traces
are available on the screen, only these are offered.
IEC/IEEE-bus command:
CALC:MARK:TRAC 2
Example:
Three traces are displayed on the screen. The marker is always on Trace 1
after switching on.
[ MKR ->TRACE ] "2" <ENTER> The marker jumps to Trace 2 but remains
at the previous frequency or time.
[ MKR ->TRACE ] "3" <ENTER> The marker jumps to Trace 3.
MKR->CF
STEPSIZE
The MKR CF STEPSIZE softkey sets the step size for the center frequency
variation to the current marker frequency, and also sets step size adaptation
to
MANUAL . CF STEPSIZE remains at this value until the center frequency
entry mode in the STEP menu is switched from MANUAL to AUTO again.
The
MKR CF STEPSIZE function is, above all, useful in the measurement
of harmonics with large dynamic range (narrow bandwidth and narrow span).
The softkey is not available in the time domain (span = 0 Hz).
IEC/IEEE-bus command:
CALC:MARK:FUNC:CST
Example:
The harmonics levels of a CW carrier are to be measured at 100 MHz.
[ PRESET ] R&S FSMR is set to the default setting.
[ CENTER : 100 MHz ] R&S FSMR sets the center frequency to 100 MHz.
The span is set to 200 MHz.
[ SPAN : 1 MHz ] The span is set to 100 MHz.
[ MKR-> ] MARKER 1 is switched on and set to the maximum
value of the signal.
[ NEXT ] R&S FSMR switches to the submenu.
[ MKR->CF
STEPSIZE ] The step size of the center frequency setting equals
the marker frequency (100 MHz).
[ CENTER ] The center frequency entry mode is activated.
[ Right key ] The center frequency is set to 200 MHz. The first
harmonic of the test signal is displayed.
[ MKR->: PEAK ] The marker is set to the harmonic and the level of
the latter is output in the marker info field.
MIN
The MIN softkey sets the active marker/delta marker to the minimum of the
selected trace.
IEC/IEEE-bus commands:
CALC:MARK:MIN
CALC:DELT:MIN
