5.2.2
Calibration (two port full calibration)
Here explains about the calibration of the directivity of 2-port-device forward direction and
inverse direction, the source match, the load match, the frequency tracking and the isolation.
By this calibration, all S parameters of 2-port-device can be measured at the highest accuracy.
The S parameter measurement is available only using the CG type network analyzer.
CAUTION!
1. If the calibration has already been executed, switch OFF the calibration, clear the calibration
data, and then start the calibration. (Refer to Section "7.5.10 Calibration Data Clear.")
2. When the message “Wait for Sweep” disappeared, each calibration completes.
The above message may not be visible if measurement time is short. A beep sound is always
heard when the calibration operation is complete.
3. During it’s displayed, the R3765/67G series, the cable, the connector, etc. must not be moved.
Select the calibration kit to be used. (refer to Section 7.5.7 Calibration Kit Selection).
Invoke 2-port full calibration menu.
