SENS:CORR:FDOF? 'queries correction value used

FETCh?
This example assumes that a table called "Table 1" is available.
Duty cycle
If the duty cycle of a pulsed signal (SENS:
DCYC
) is reported to the R&S NRP2, the
R&S NRP2 delivers the average power in the pulse.
Example
*RST
SENS:CORR:DCYC:STAT ON 'duty-cycle correction
SENS:CORR:DCYC 30 PCT 'duty cycle of 30%
INIT
FETCh?
Reflection coefficient of the source (source gamma, Γ )
Reflections at the power source may distort the result. If the reflection coefficient of the
source is known, it can be specified for the measured-value correction via command
path SENS:SGAM.
Example
*RST
SENS:SGAM:CORR:STAT ON 'considers the reflection coefficient of the source
SENS:SGAM:MAGN 0.01 'magnitude of the reflection coefficient
SENS:SGAM:PHAS 179 'phase angle of the reflection coefficient

A.4.4.4 Configuration of CALCulate blocks
The function of the CALCulate blocks has already been explained. Its most important
task is the calculation and provision of measurement results.
Calculation function and relative measurement
The calculation functions mentioned in connection with high-level commands are inter-
nally implemented via commands CALC:MATH and CALC:REL:STAT.
