Suitable for FM walkie-talkie debugging.

Built-in 800Hz audio modulation, with the analog digital CTCSS function.

The unit is DBM. General hand sensitivity is -120DBM to -130DBM.

The greater the sensitivity to a negative number, the higher the sensitivity.

The signal source cannot input power.

It is absolutely forbidden to press the intercom button to transmit when testing. (self-matching power supply 8V-12V power supply polarity is positive and negative)

Test methods:

During the test, the frequency of the signal source input transceiver is first set to -100DB or any value. The intercom has audio output and then reduces the output strength of the source. For example, the -120DB just heard the intercom audio signal but there was noise. The audio signal just hears that the -120DB value of this output is the receiving sensitivity of the radio.

1. Power cable is not included.

2. Specially designed for testing the sensitivity of your walkie talkie, the signal generator meter is not for testing the sensitivity of FM radios. It features narrow-band FM mode different from that of radios.
