SENSe:CORRection
Sensor power offsets apply to the individual sensor. Use sensor offsets to account for the loss of attenuators,
which are commonly used during measurement to reduce standing waves to improve measurement accuracy. If
measuring high power signals (>100 mW), but are not using Giga-tronics high power sensors, use a power
attenuator between the high power output and the sensor input to prevent damage. Enter the value of
attenuation as a sensor offset, and the 8650B will automatically respond with the actual power level output in
its measurement data.
SENSe:CORRection
Syntax: SENSe<sensor 1 or 2>:CORRection:OFFSet:COLLect
Example:
SENS1:CORR:OFFS:COLL ! TAKE SENSOR 1 CURRENT READING AS THE OFFSET VALUE
Description: This command enters the current power level reading as the offset value.
Syntax:
SENSe<sensor 1 or 2>:CORRection:OFFSet[:MAGnitude] space
< offset value in dB, -99.99 to 99.99>
Example:
SENS2:CORR:OFFS 10.2 ! COMPENSATE SENSOR 2 FOR 10.2 DB ATTENUATION
Description: This command enters a specific sensor offset value.
Syntax: SENSe<sensor 1 or 2>:CORRection:OFFSet:STATe space <ON | OFF>
Example:
SENS2:CORR:OFFS:STAT ON ! ENABLES SENSOR 2 OFFSET CORRECTION
Description: This command activates and deactivates the sensor offset function.
