10.45 Calibration
– System Isolation Tests
This page is used for (optionally) calibrating the individual Tx Port to Rx Port Antenna Isolation values.
As each Tx Port is normally connected to a different antenna system, the antenna isolation between that Tx antenna and the Rx
antenna is likely to be different than that between the other Tx antennas and that same Rx port, and different to the average value
measured in the Antenna Isolation Test.
If desired, this page allows the different values for each Tx Antenna to Rx Antenna isolation to be set up for each port. This
calibrated value will then be used in determining the Tx Rejection value for configured channels on each specific port in the System
Isolation Tests’ Tx Rejection Tests.
If the calibration isolation value is left blank, the system measured Antenna Isolation Test value will be used for the Tx Rejection
Tests measurements for the Tx port.
Calibration Process:
Disconnect all of the connected Tx Reverse ports’ coaxial cables. Re-connect the cables, with only one connected at a time, and
click the associated Test & Capture button. Clicking this button immediately initiates a new Antenna Isolation Test measurement,
and loads the result into the Isolation field associated with that port.
Complete this process, having only one Tx Reverse ports’ coaxial cable connected each time, until all used Tx Ports have been
calibrated.
Re-
connect all Tx Reverse ports’ coaxial cables.
