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 ESCI is set to the default setting.
[CENTER: 100 MHz] R&S ESCI 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 ESCI 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
NEXT MIN
The NEXT MIN softkey sets the active marker/delta marker to the next higher
minimum of the selected trace. The search direction is defined in the NEXT
MODE submenu (see above).
IEC/IEEE-bus commands: CALC:MARK:MIN:NEXT
CALC:DELT:MIN:NEXT
