CALCulate Subsystem
• CHPower - no markers
• EVMQpsk - markers available
• PSTatistic - markers available
• RHO - markers available
• SPECtrum - markers available
• WAVeform - markers available
Example:
Suppose you are using the Spectrum measurement. To position marker
2 at the maximum peak value of the trace that marker 2 is currently on,
the command is:
:CALCulate:SPECtrum:MARKer2:MAXimum
You must make sure that the measurement is completed before trying
to query the marker value. Use the MEASure or READ command before
using the marker command. This forces the measurement to complete
before allowing the next command to be executed.
Markers All Off on All Traces
:CALCulate:<measurement>:MARKer:AOFF
Turns off all markers on all the traces in the specified measurement.
Example: CALC:SPEC:MARK:AOFF
Remarks: The keyword for the current measurement must be
specified in the command. (Some examples include:
SPECtrum, WAVeform)
