Introducció
This manual provides instructions for the operation and maintenance of the 0.5MHz-470MHz RF Signal Generator. This device is designed for debugging FM radios and walkie-talkies, offering high accuracy in signal generation. It features built-in 800Hz audio modulation and analog digital CTCSS function for comprehensive testing.

Precaucions de seguretat
- The signal source cannot input power directly from the device being tested.
- It is strictly forbidden to press the intercom button to transmit when testing with this signal generator. Doing so may damage the unit.
- Ensure the power supply polarity is correct when connecting the 8V-12V DC power adapter.
Configuració
To set up your RF Signal Generator:
- Connect a compatible 8V-12V DC power supply to the DC input port on the rear of the device. Ensure correct polarity (positive and negative).
- Connect the RF OUT port of the signal generator to the input of the device you wish to test (e.g., a walkie-talkie) using an appropriate RF cable.

Instruccions de funcionament
The RF Signal Generator is equipped with a digital display and control buttons for setting frequency and signal strength.
Característiques principals:
- Built-in 800Hz audio modulation.
- Analog digital CTCSS function for advanced testing.
- Frequency display shows 7 digits (e.g., 439.6000MHz is displayed as 4396000KHz).
- Signal strength is measured in DBM.


Test Methods for Walkie-Talkie Sensitivity:
To test the actual receiving sensitivity of a walkie-talkie:
- Set the frequency of the signal generator to match the desired test frequency for the walkie-talkie.
- Initially set the signal source output strength to a value like -100DB.
- Observe if the intercom (walkie-talkie) produces audio output.
- Gradually reduce the output strength of the signal source.
- Per example, if at -120DBM you hear the intercom audio signal but with noise, and then at -122DBM the audio signal is clear, the -122DBM value represents the receiving sensitivity of the radio.

Manteniment
To ensure the longevity and optimal performance of your RF Signal Generator:
- Mantingueu el dispositiu net i lliure de pols. Feu servir un drap suau i sec per netejar-lo.
- Eviteu exposar el dispositiu a temperatures extremes, humitat o llum solar directa.
- Guardeu el dispositiu en un lloc segur quan no l'utilitzeu per evitar danys físics.
- No intenteu obrir la casing or perform internal repairs, as this may void any potential warranty and cause damage.
Resolució de problemes
If you encounter issues with your RF Signal Generator, consider the following:
- Sense energia: Ensure the 8V-12V DC power supply is correctly connected and functioning. Check the power adapter and outlet.
- No Signal Output: Verify that the RF cable is securely connected to both the signal generator's RF OUT port and the device under test. Confirm the frequency and signal strength settings on the generator's display.
- Lectures incorrectes: Ensure the device under test is properly calibrated and configured for the test. Double-check all connections.
- El dispositiu no respon: Disconnect the power, wait a few seconds, and then reconnect to perform a soft reset.
