0.5MHz 470MHz Radio Frequency Signal Generator Meter Tester for FM Radio Walkie talkie Debug Digital CTCSS Singal Output

Feature: 1. Suitable for FM walkie talkie debugging. 2. The unit is DBM. General hand sensitivity is 120DBM to 130DBM. 3. The greater the sensitivity to a negative number, the higher the sensitivity. 4. The signal source cannot input power. 5. It is absolutely forbidden to press the intercom button to transmit when testing. (self matching power supply 8V 12V power supply polarity is positive and negative) Specification: 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. 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 absolutely 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 this output is the receiving sensitivity of the radio. Package list: 1 * 0.5MHz 470MHz Signal Generator for FM Radio.
