7-4 Calibration Procedures
In Vector Network Analyzer Mode, calibration is required when the test port
cable or adapters have been changed or when no valid calibration is available
(Cal Status --). The following sections describe how to perform calibrations.
Calibration Procedure
1. Press the Freq/Dist main menu key and enter the appropriate frequency
range.
2. In the Sweep menu, set the source power level.
3. Press the Calibration main menu key, then press Start Calibration.
4. Press Cal Setup to make changes to the setup as needed (refer to
Section 7-3 “Calibration Setup” on page 7-5).
5. Press Measure and follow the on screen instructions (see Figure 7-11
on page 7-18).
6. Verify that the calibration has been completed by confirming that the
Cal Status message is now displaying “Cal: OK”. The calibration
correction factor will then be applied to the measurements.
7. The calibration factors can be turned Off with the Cal Correction button.
The calibration coefficients are saved and can be reapplied by setting
Cal Correction back to On.
Note
If a Test Port Extension Cable is to be used (this is
recommended), then it must be connected to the Site Master
before calibration.
