Gain/Phase Mode
The phase readout of 48.5º is not the value you want to measure because it is
the sum of the phase shift of the cables and of the IF filter. To get the value of
the IF filter only, use the Gain/Phase calibration to compensate the phase shift
of the cables.
Continue the example and calibrate the Bode 100 to get the phase shift of the IF
filter:
1. Replace the IF filter with the BNC straight adapter (f–f).
2. Click the User Calibration toolbar button to open the
calibration window.
3. In the calibration window, click Start in the Gain/Phase area.
The calibration takes only a few seconds. The Gain/Phase mode is now
calibrated for the current specific measurement setup.
