In Cable and Antenna Analyzer Mode, calibration is required when the “Not Calibrated” message is displayed or when the test port cable has been changed. The following sections detail how to perform OSL and InstaCal calibration.
Note
If a Test Port Extension Cable is to be used, it must be connected to the Site Master before calibration. Follow the same calibration procedures with the OSL components or the InstaCal module in place at the end of the test port extension cable.
OSL Calibration Procedure (Standard and FlexCal)
Calibration Setup OSL Cal
1. Press the Freq/Dist main menu key and enter the appropriate frequency range
2. Press Shift then Cal (2) key.
3. Select Standard or FlexCal.
4. Press Start Cal and follow instructions on screen.
5. Connect Open to RF Out and press the Enter key.
6. Connect Short to RF Out and press the Enter key.
7. Connect Load to RF Out and press the Enter key.
8. Verify that the calibration has been properly performed by checking that the Cal Status message is now displaying “ON, Standard” or “ON, FlexCal”.
InstaCal Module Calibration Procedures (Standard and FlexCal)
Calibration Setup InstaCal
1. Press the Freq/Dist main menu key and enter the appropriate frequency range.
2. Press Shift then Cal (2) key.
3. Select Standard or FlexCal.
4. Press Start Cal. The message “Connect OPEN or InstaCal to RF Out port” will appear on screen.
5. Connect the InstaCal module to RF Out and press the Enter key.
6. The instrument senses the InstaCal module and automatically calibrates the unit using the OSL procedure. An audible tone will sound when the calibration is complete.
7. Verify that the calibration has been properly performed by checking that the Cal Status message is now displaying “ON, Standard, Insta” or “ON, Flex, Insta”.
Note
The InstaCal module is not a discrete calibration component and it can not be used at the top of the tower to perform line sweep measurements.
