CALCulate[1]|2|3|4:MATH[:EXPRession] <string>
This command sets the specified window/measurement to a single channel,
difference or ratio measurement.
The command may result in a change to the measurement mode set by
CALC:FEED <string>. The following sequence of commands provides an example:
1 SENS2:DET:FUN=AVERage
2 CALC:MATH “(SENS1)”
3 CALC:FEED1 “POW:PEAK”
4 CALC:MATH “(SENS2)”
The FEED1 measurement mode, set in step 3, is made invalid by step 4 and
automatically changed to “POW:AVER”.
