Signal Generator 0.5MHz-470MHz RF Signal Generator Meter

Model Number : Signal Generator Display Size : 7 Inches amp; DIY Supplies : ELECTRICAL Brand Name : KKMOON Origin : Mainland China 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 walkie-talkie. Features: 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 ly forbidden to press the intercom button to transmit when testing. (self-matching power supply 8V-12V power supply polarity is positive and negative) Specifications: Material: ABS Color: blue Frequency: 0.5MHz-470MHz Signal strength: -70-132dBm Built-in 800Hz audio modulation Add the analog digital CTCSS function Use 8-12V DC power supply, frequency 7 digits For example: 439.6000MHz shows 4396000KHz Signal strength -70-132dBm valid, other values are invalid. Audio modulation is only about 800Hz, other values are invalid. Item size: 155 * 120 * 63mm / 6.1 * 4.7 * 2.5in Item weight: 271g / 9.6ounce Package size: 210 * 160 * 70mm / 8.3 * 6.3 * 2.8in Package weight: 303g / 10.7ounce 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
