MKR->TRACE The MKR->TRACE softkey sets the active marker to a new trace.
For further information refer to the descriptions in section
"Change of Settings via Markers – MKR-> Key" on page
MKR->CF The MKR->CF STEPSIZE softkey sets the step size for the center frequency varia-
STEPSIZE tion 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 har-
monics with large dynamic range (narrow bandwidth and narrow span).
The softkey is not available in the time domain (span = 0 Hz).

Example:
The harmonics levels of a CW carrier are to be measured at 100 MHz.
