Description
The device is designed to generate high-frequency signals at frequencies of 0.5 MHz – 470 MHz, with the possibility of their modulation by an audio signal with a frequency of 800 Hz. Allows you to smoothly adjust the RF signal strength within -70 – 132 dBm. It can be used to measure the sensitivity and selectivity of the receiving paths of various devices, as well as for other purposes.

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