0.5MHz-470MHz RF Signal Generator Tester for FM Debug CTCSS Singal Output B4K7

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)

Package weight: 303g / 10.7ounce
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 .
