Test Now:
The "Test Now" button can be selected at any time to manually initiate a System Isolation Tests measurement.
All of the measurement fields may take time to populate subject to when the Tx frequencies configured in the test next transmit.
The 'Test Now" button will display
Note:
During a System Isolation Test, results that have not yet been measured (i.e. because the nominated Tx frequency has
not yet keyed) will be highlighted by a shaded background colour. As each test is able to be completed, and a result
recorded, that measurement's value will change to having a solid background colour. It may take some time for all tests
to be completed and a measurement result recorded – depending on channel activity at the time of the test.
The background behind a measurement value is highlighted in colour to indicate its current status, as follows;
Green denotes 'no alarm', a Pale Green background denotes a measurement of a previous 'no alarm' value is yet to
be completed, Red denotes 'alarm', a Pale Red background denotes a measurement of a previous 'alarm' value is yet
to be completed, a Pale Yellow background denotes the Ant Iso value is a calculated average (i.e. the value for the
specific port has not been calibrated, and White denotes a measurement result is not available.
Note:
The Rx System performance values that can be measured in the System Isolation Tests are a function of the overall test
configuration. If the resulting measurement is beyond the APM's measurement sensitivity, '???' will be
displayed in lieu of a value.
When a Receive Systems Module (RSM) is fitted to the APM, the measured values for the three receive signal paths (RxA, RxB
and RxE) are visible in the Status – System Isolation Tests page.
