Irfora 0.5-470MHz RF Signal Generator - Professional FM Radio & Walkie Talkie Tester with Digital CTCSS Signal Output for Ham Radio, Communication Equipment Testing & Field Debugging

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. Specifications: Material: ABS Color: blue Frequency: 0.5-470 Signal strength: -70-132dBm Built-in 800Hz o modulation Add the analog digital CTCSS function Use 8-12V DC power ply, frequency 7 digits For example: 439.6000 shows 4396000KHz Signal strength -70-132dBm valid, other values are invalid. o 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 o output and then reduces the output strength of the source. For example, the -120DB just heard the intercom o signal but there was noise. The o signal just hears that the -120DB value of this output is the receiving sensitivity of the radio. Package list: 1 * 0.5-470 Signal Generator for FM Radio
