Subsystem RFANalyzer:CONTrol
The subsystem RFANalyzer:CONTrol defines the repetition mode of the RF analyzer. This subsystem
has no equivalent in manual control.

Command description
This command determines the number of statistics cycles and the stepping mode for the measurement. A stop
condition is not available.
Note: In the case of READ commands (READ: to ) the <Repetition> parameter has no effect; the measure-
ment is always stopped after a single shot.

0 to 1 Duration of measurement. Accuracy: ± 5E-10 s 20E-3 s V1.15
Command description
This command defines the time period during which the peak power is determined. With the time 0, the power is
immediately measured on the measurement start, i.e. the instantaneous value is measured.
Results – Subsystem RFANalyzer:POWer?
The subsystem RFANalyzer:POWer starts the analyzer power measurement and returns the results.
The subsystem corresponds to the Analyzer Power panel in the Analyzer/Generator menu.
Scalar measurement results:
READ[:SCALar]:RFANalyzer:POWer? Start single shot measurement and return results
FETCh[:SCALar]:RFANalyzer:POWer? Read out measurement results (unsynchronized)
SAMPle[:SCALar]:RFANalyzer:POWer? Read out measurement results (synchronized)

Command description
These commands are always queries. They start a measurement and return the scalar measurement result.
