Wide Frequency Range: This signal generator covers a wide frequency range of 1MHz to 470MHz, allowing you to generate signals suitable for various applications. Suitable for sound modulation, transceiver signal processing, and other projects. 2. Relay Station Testing: Specifically developed for debugging and measuring U/V relay stations and FM receivers. This signal generator can operate in duplex mode, the tested machine is in the transmitting state without affecting its running. It can be applied for measurement in the forwarding state of the transfer station. 3. Accurate and Reliable: This signal generator has simple use and high reliability. With intuitive control and clear display, making settings and use easier. With a sturdy structure and stable performance, providing consistent and accurate signal generation. 4. Multiple Functions: This FM tester supports receiving and transmitting measurements, ensuring stability and reliability. In signal source mode, more testing functions can be achieved. Suitable for aviation, wireless comm, automotive electronics, manufacturing, and other fields. 5. Convenient and Practical: The FM comprehensive tester has a simple structure, multiple button controls, which is convenient and practical. The lightweight design makes it easy to use and carry, making it convenient to use at any time. Specification: Item Type: FM Tester Working Voltage: 8-12V DC Working Current: 200mA Transmitting Measurement: 1. Frequency Measurement: 10M-900M, Resolution 1K or 0.1K 2. Power Measurement: 0.1W-64W 3. Subaudio Measurement: 50Hz-260Hz, analog subtone and standard digital subtone Receiving Measurement: 1. Signal Generator Frequency: 1MHz-470MHz 2. Output Level: -132dBm to -90dBm 3. Single Tone Modulation: 1KHz, 2KHz, 3KHz optional, output modulation depth: 3K 4. Subtone Output: 50Hz-260Hz analog subtone and standard digital subtone, output amplitude: 0.5K Signal Source Mode: First Line Left: Frequency (0.5-470M), Right: Output Power (-90-131dBm) Second Line Left: Subaudio (50.0-280.0Hz Any Analog Subtone and 105 Digital Subtone), Right: Modulation Tone (1-3K), Lower Right Corner Display Input Power Numeric Key: For direct input of cursor indicated item Up and Down Key: Step adjustment of cursor indicated item value F1 Key: Cursor Pointing Movement (long press to switch to frequency counter mode) F2 Key: Backspace Key F3 Key: Function key, when the cursor points to output power, subaudio, and modulation tone, it is a cyclic switching function, e.g., when the cursor points to power output, this key function is to cyclically switch the signal output. F4 Key: Not Use Analog Subtone Setting: Directly enter subaudio point with 4 digits, if less than 4 digits, fill in 0 in front, e.g., 88.5Hz input 0, 8, 8, 5; now if you use up and down keys to adjust, it will be adjusted in steps of 0.1Hz; if you need to adjust in 50 standard subtones, you need to enter 0, 0, 0, 0, and then use up and down keys to adjust from the first standard subtone 67Hz. Digital Subtone Setting: Enter 3 digit digital subtone code and then press F3, e.g., 023, enter 0, 2, 3, and then press F3 to set successfully; press F2 key to switch between I and N in digital subtone, adjust up and down keys in 105 sets of digital subton Modulating tone and subtone values Input 0 is equivalent to off. Step frequency setting: When the cursor points to the frequency, long press F3 to save the current displayed frequency as step frequency. Frequency meter mode: First Line: Left: frequency, right: Measurement mode AUTO/ MANUA (In order to simultaneously measure the transmissing subtone of the intercom or repeater, please select AUTO mode) second line: left: subaudio, right: frequency resolution (1K/0.1K) (in order to test the frequency of the transmissing frequency of the intercom or repeater can choose 0.1k will be more accurate), the input power is displayed in the lower right corner Digit Key: Not Use Up or Down: Not Use F1 Key: Press and hold to switch to signal source mode F2 Key: Not Use F3 Key: Frequency meter resolution switch 1K/0.1K F4 Key: When the measurement mode is switched between AUTO or MANUA, at AUTO, the stable frequency is detected and automatically locked, the subtone is detected and the result is displayed until the signal disappears. After the signal disappears, the detection continues to wait for the new stable frequency. (You can detect the standard and non standard analog subtones emitted by the radio by yourself. If the radio emits digital subtones, only standard digital subtones can be
