Product Name: 0.5Mhz-470Mhz RF Signal Generator Meter Tester for FM Radio Walkie-Talkie Debug
This versatile tool is specifically designed for FM walkie-talkie debug processes. The RF Signal Generator Meter Tester boasts a frequency range of 0.5M to 470M, which offers ample coverage for testing and analysis.
This instrument provides a signal strength ranging from -70 to 132dBm. Additionally, it comes equipped with an inbuilt 800Hz tone modulation for comprehensive testing of your devices. This unit is powered by a DC power supply within the range of 8 to 12V.
With an easily readable 7 digit display, you can keep track of frequencies up to the decimal place. For example, it would display 4390125 for a frequency of 439012.5KHZ. It ranks high on ease of use with value direct input selection through number keys and numerical stepping modification via arrow keys.
When it comes to audio modulation, the valid frequency is 800Hz, with other values being considered invalid. There are different key functions: F1 for cycling setting items like frequency, signal strength, and audio modulation frequency. F2 serves as a backspace key in case of input error, F3 for toggling signal output, and F4 for toggling audio signal modulation.
The package includes one 0.5Mhz-470Mhz RF Signal Generator Meter Tester unit.
The operation method is as follows:
F1: Cycle selection setting item “” points to the selected item, respectively frequency, signal strength, audio modulation frequency
F2: Backspace key when entering an error
F3: Turn off and turn on the signal output
F4: Turn off and turn on the audio signal modulation|
Number key: directly enter the value of the selected item
Up and down keys: step by step to modify the value of the selected item
note:
The input power is forbidden. Once the input exceeds 0dbm, the signal source will be burned out. The damage caused by the input power is not covered by the warranty.
Interphone signal source description
Source mode:
First line left frequency (0.5-470M), right side output power (-90 — -131dBm)
The second line to the left of the sub-audio (50.0-280.0Hz arbitrary analog sub-tone and 105 sets of digital sub-tones) right modulation tone modulation (0-3K) (0k is the off modulation tone)
Number key: direct input for the cursor pointing to the item
Up and down keys: step adjustment cursor points to the item value
F1 key: cursor pointing to move
F2 key: Backspace key
F3 key: Function key When the cursor points to the output power, sub-tone, and modulation sound, it is the cycle switch function. For example, when the cursor points to the power output, the key function is the cycle switch signal output.
F4 button: not used
Analog sub-tone setting: directly input the sub-audio point 4 digits, not enough 4 digits front “0”, 88.8 Hz input 0, 8, 8, 5
Now if you use the up and down keys to adjust it in 0.1Hz steps, if you need to input 0, 0, 0, 0 with the standard 50 sets of subsonic adjustment, then use the up and down keys to adjust from the first standard subsonic 67Hz. .
Digital sub-tone setting: input 3 digits sub-tone code and press F3. 023 first input 0, 2, 3 and then press F3 to set successfully. Press F2 to switch between digital and sub-tones I and N. The key will be added or subtracted from the 105 sets of digital subtones.
The value of 0 for the modulated and sub-tones is equivalent to off.
Step frequency setting: When the cursor points to the frequency, long press the frequency currently displayed by F3 to save as the step frequency.
Quickly enter the integer frequency: for example, input 4, 3, F3 is 430.0000
