7.3.2 PROCEDURE
1. Remove the 8x T20 screws from the perimeter of the radio.
2. Pull the 2 clamshell halves away from each other, separating them at the interface end and pivoting at the
other end. Ensure that you don’t lose the two small O-ring seals which sit on chassis pillars as shown
above.
3. Disconnect the 4x SMB connectors from the RF Board. Long nose pliers are the best tool to remove the
connectors otherwise it can be difficult to grip the connector. Don’t simply pull or leaver up the cable as
this will damage the coax at the SMB interface. You can use the SMB connectors on the semi-flexible
coax as the test interface by using the appropriate SMB male adapter. This can be more convenient than
removing the entire duplexer from the chassis.
4. Calibrate/set up the network analyser to the desired frequency band. It helps to limit the source power to
-15dBm so as not to overload the LNA in the Rx path.
