CFFRQ (Cal Factor Frequency value)
CFSRC (Cal factor source)
Syntax: CFFRQ <s>, <value>[units]
s: A or B
value: 10 kHz to 122 GHz
Remarks: Sets the frequency used to look up the correction data from the sensor’s
internal table.
Example: Both of the following examples set the frequency for cal source
frequency to 25 GHz for sensor A.
CFFRQ A,25E9
CFFRQ A,25GHZ
Query: CFFRQ? <s>
Returned String: CFFRQ <s>,<value>
Syntax: CFSRC <s>,<source>
s: A or B
source: FREQ MAN VGHZ
Remarks: Sets the source of the calibration factor. Frequency uses the internal
EEPROM calibration factor value in the sensor, from the frequency set
by the CFFRQ number. Frequencies between Cal Factor data points are
interpolated linearly to 0.01 dB resolution.
Manual uses the CFCAL number itself.
VGHz takes the frequency from the V/GHz input and uses it to look up
the calibration factor from the EEPROM in the sensor.
