0.5MHz-470MHz RF Signal Generator & Meter for FM Radio, Walkie-Talkie Debugging with Digital CTCSS Signal Output

Introducing the high-accuracy RF Signal Generator, ideal for testing and debugging FM walkie-talkies. Designed to deliver precise results comparable to professional comprehensive measurement tools, this device accurately tests the receiving sensitivity of your walkie-talkie with ease.

Features:

• Perfect for FM walkie-talkie debugging.
• Built-in 800Hz audio modulation with analog and digital CTCSS function.
• Measures in DBM; typical hand sensitivity ranges from -120DBM to -130DBM.
• Higher sensitivity is indicated by a higher negative number.
• Signal source is not powered; do not press the intercom transmit button during testing.
• Compatible with 8V-12V power supply, polarity must be observed.

• Package size: 210 x 160 x 70 mm (8.3 x 6.3 x 2.8 inches)
• Package weight: 303g (10.7 ounces)

Test Methods:

To conduct a test, set the frequency of the signal source input transceiver to -100DB or another value. Allow the intercom to output audio, then reduce the output strength of the source. If the intercom's audio signal is audible at -120DB but with noise, this value represents the receiving sensitivity of the radio.
