0.5MHZ-470MHZ Generator, Generator Audio Modulation Source Conditioning Radio 800Hz With Analog Digital CTCSS Function For FM Walkie-talkie Debugging

Features:Suitable for FM walkie-talkie debugging.Built-in 800Hz audio modulation, with analog digital CTCSS function.The unit is DBM. The general sensitivity is -120DBM to -130DBM.The closer the sensitivity is to a negative number, the higher the sensitivity.The signal source cannot be input with power.It is strictly forbidden to press the intercom button to transmit during the test. (The polarity of the self-assembled power supply 8V-12V power supply is positive and negative)The accuracy of this signal source is basically consistent with the professional comprehensive measurement results. The accuracy is very high. The actual receiving sensitivity of the walkie-talkie can be tested.Specifications:Part Name: Intercom Signal GeneratorMaterial: ABSColor: BlueFrequency: 0.5MHz-470MHzSignal Strength: -70-132dBmMaximum Sensitivity: -70dbmBuilt-in 800Hz audio modulationAdd analog digital CTCSS functionUse 8-12V DC power supply, frequency 7-digit displayFor example: 439.6000MHz means 4396000KHzSignal Strength -70-132dBm is valid, other values are invalid.Audio modulation is only for 800Hz, other values are invalid.Dimensions: 155 * 120 * 63mm / 6.1 * 4.7 * 2.5inProduct weight: 271g / 9.6ozPackaging size: 210 * 160 * 70mm / 8.3 * 6.3 * 2.8inPackaging weight: 303g / 10.7ozTest way:During the test, first set the frequency of the signal source input to the transceiver to -100DB or any value. The intercom has audio output, and then reduce the output strength of the signal source. For example, -120DB just hears the intercom audio signal, but there is noise. The audio signal is just heard, and the -120DB value of this output is the receiving sensitivity of the intercom.Package Contents：1 * 0.5MHz-470MHz FM radio RF signal generator
