Section 2 Interface Description
1. T/R interface
This is an RF signal interface and can be applied to send the signal of the internal RF Source
1 or as the receiver input end to receive RF signals to be tested. The sensitivity of this port is low.
Note that the input signal must pass through this port in the broadband RF high power test.
2. ANT interface
This port is an RF signal interface and can be applied to the signal of the internal RF Source
1 or 2 or the combined signal, or receive the RF signal to be tested. It has high sensitivity.
Generally, it is connected to the tested radio system for radio test or connected to the antenna input
test signal.
3. SWR interface
This port is an RF signal output interface, and can be applied to send the signal of the internal
RF Source 1, or test the standing wave ratio, insertion loss, return loss and other indicators of the
cable by comparison of output and reflected signals so as to determine the distance-to-fault of the
cable.
4. Audio box interface
The multi-core plug of this port includes the audio input and output signal information. This
power can be connected to the external audio box or tested audio device for calling or testing of
the external audio device.
5. GPS interface
This port is connected to the GPS antenna to determine the current location of the tester.
6. AUDIO OUT interface
This port is applied to output the separate signal of the Audio Source 1, Audio Source 2 or
noise source, or output the combination of any two signals.
7. AUDIO IN/DVM interface
This port is applied as the external audio input or digital voltmeter test signal input end.
