0.5MHz-470MHz RF Signal Generator Meter Tester for FM - H7S3

Description

The accuracy comparison between this signal source and professional comprehensive measurement is basically the same. The accuracy is very high. Can test the actual receiving sensitivity of the -.
Features:
Suitable for FM - debugging.
Built-in 800Hz audio modulation, with the 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 .
It is forbidden to press the button to transmit when testing. (self-matching 8V- polarity is positive and negative)

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