Initial S/W Revision A.07.00
CF à Signal (Replace)
Replaces the frequency of the selected signal with the Center Frequency (and Meters Freq since they are
the same). Amplitude values and Delta To Limit values will be shown as “---“ to indicate that those values
are undefined until the next scan/final measurement value.

Example CALC:MON:SLIS:REPL:MET 20 Replace Signal #20 with Center Freq
Notes If the signal list contains no data, an error is generated and this function cannot be performed.
If the selected signal is not in the list, an error is generated and this function cannot be performed.
