RADIO TESTS WITH THE RADIO TEST SET
7.2.1
Tests with Radio Test Set
To carry out the Power Test and the Sensitivity Test on the radio terminal, you
need a TETRA RADIO TEST SET (IFR) with the power supply cable and a TNC
cable, as well as the radio terminal to be tested.
Note
Several functions can be active on the TETRA TEST SET, depending on the release.
To carry out the test:
•
turn off the RADIO;
•
disconnect the antenna from the RADIO and replace it with the TNC cable;
•
connect the other end of the TNC cable to the TETRA RADIO TEST SET; turn
on the TETRA RADIO TEST SET (see Fig. 7.1).
Note
If the radio terminal to be tested is a portable one (Puma T2/T3), connect to the test set on the most
sensitive RF connector (1W); to select this connector, press the “RF select” button; the two leds next to
the connection selected will light up. By default, the Tetra Radio Test Set sets itself on the least
sensitive RF connection (150 W), signaling it with the lighting up of the relative leds; this connection
should be used in all cases in which the radio to be tested supplies a maximum power greater than 1
Watt.
