InstaCal Module Calibration Procedure
The InstaCal module automatically calibrates the Site Master using the OSL method.
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.
Check that the “CAL OFF” message is displayed in the upper left corner of the display.
This indicates that the Site Master has not been calibrated. The following procedure details
how to perform the calibration using the InstaCal module.
Step 1. Select the appropriate frequency range, as described in the procedure above.
Step 2. Press the
START CAL
key. The message “CONNECT OPEN or InstaCal TO RF
Out PORT” will appear in the display.
Step 3. Connect the InstaCal module to the RF Out port.
Step 4. Press the
ENTER
key. The Site Master senses the InstaCal module and automati-
cally calibrates the unit using the OSL procedure. The calibration should take
about 45 seconds.
Step 5. Verify that the calibration has been properly performed by checking that the
CAL ON!
message is displayed in the upper left corner of the display.
Calibration with the Test Port Extension Cable
If a Test Port Extension Cable is to be used, the Site Master must be calibrated with the
Test Port Extension Cable in place. Follow the same calibration procedures as above with
the OSL components or the InstaCal module in place at the end of the test port extension
cable.
