Calibration of Reflection Measurement
The calibration mechanism
essentially corresponds to that of the transmission measurement.
NETWORK-SOURCE CAL submenu
CAL REFL
OPEN
The CAL REFL OPEN softkey starts the open-circuit calibration. During
calibration the following message is displayed:
IEC/IEEE-bus command
CORR:METH REFL
CORR:COLL OPEN
CAL REFL
SHORT
The CAL REFL SHORT softkey starts the short-circuit calibration.
If both calibrations (open circuit, short circuit) are carried out, the calibration
curve is formed by averaging the two measurements and stored in the
memory. The order of measurements is optional.
After the calibration the following message is displayed:
The display is cleared after approx. 3 seconds.
