Calibration of Reflection Measurement
The calibration mechanism for reflection measurement is basically the same as the one used for
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 calculated by averaging the two measurements and stored in the
memory. The order of the two calibration measurements is free.
After the calibration the following message is displayed:
The message is cleared after approx. 3 seconds.
IEC/IEEE-bus command: CORR:METH REFL
