High Frequency Signal Source RF Signal Source 0.5-470MHz FM FM Walkie Talkie Sensitivity Testing
High frequency signal source, RF signal source (0.5-470MHz)
1.Specialized for FM walkie-talkie debugging
2.Frequency 0.5MHz-470MHz
3.Output signal strength -70 to -132dBm (other values are invalid)
4. Built-in 800Hz audio modulation (FM mode modulation) (other values are invalid)
5. Using 8-12V DC power supply
6. Frequency 7 digits, for example: 439.0125MHz shows 4390125 if it is 439.125MHz shows 4391250.
7. (Prohibit input power, once the input power over 0dbm will burn out the signal source) due to input power burned out is not under warranty.
(Input power is prohibited, once the input power exceeds 0dbm, it will burn out the signal source) Remember!!!!
8. Randomly without power supply, without test line, without paper manual, the specific operation method is described in the web page.
9. Net weight: 300 grams
10.Dimensions:160*130*65mm(without bracket)
Operation method is as follows.
F1: Cycle selection settings project “《” pointing to the selection of the project, respectively, the frequency, signal strength, audio modulation frequency
F2: backspace key when inputting error
F3: close, open the signal output
F4:Close, open the audio signal modulation
NUMBER KEYS: Directly input the value of the selected item.
Up and down keys: Step to modify the value of the selected item.
Note: The power input is prohibited.
It is forofferden to input power, once inputting more than 0dbm power, it will burn the signal source, and the damage caused by inputting power is not under warranty.

Walkie Talkie Signal Source Description
Signal source mode.
First line left frequency (0.5-470M), right output power (-70 to -132dBm)
Second line left sub-tone frequency (50.0-280.0Hz any analog sub-tone and 105 groups of digital sub-tone) right modulation tone system (0-3K) (0-3K) (0-3K)
K) (0k is off modulation tone)
NUMBER KEYS: Direct input for the cursor pointing to the item.
Up and down keys: step adjustment of the value of the cursor pointing item.
F1 key: Cursor pointing movement
F2 key: Backspace
F3 key:Function key When the cursor points to the output power, sub-tone, modulation tone, it is a cycle switch function, for example: when the cursor points to the power output, the key functions as a cycle switch signal.
Example: When the cursor points to power output, the key functions as cycle switch signal output.
F4 key: not used
Analog Subtone Setting: directly input the 4 digits of the sub-tone frequency point, and make up “0” in front of the insufficient 4 digits, e.g., input 0, 8, 8, 5 at 88.8 Hz.
Now if you use the up and down keys to adjust will be adjusted in steps of 0.1Hz, if you need to adjust to the standard 50 groups of sub-tones to enter 0,
If you need to adjust by the standard 50 sub-tones, you have to input 0, 0, 0 and then use the up and down keys to adjust from the first standard sub-tone 67Hz.
Digital Subtone Setting: Input the 3 digit Subtone code and then press F3 Example 023 Input 0, 2, 3 and then press F3 to set it up successfully.
Pressing the F2 key will toggle between I and N for the digital sub-tones, and adjusting the up and down keys will add or subtract from the 105 sets of digital sub-tones.
Inputting 0 for the value of modulating tone and sub-tone is equivalent to turning off.
Step Frequency Setting:When the cursor is pointing to the frequency, long press F3 to save the current displayed frequency as step frequency.
Quickly enter the integer frequency: for example, enter 4, 3, F3 is 430.0000
Special Note: This signal source is mainly used for testing analog signal.
This signal source is mainly used to test the sensitivity of analog walkie-talkie, belongs to the narrow-band FM mode, is not suitable for testing the reception sensitivity of the radio, and the signal source is not suitable for testing the reception sensitivity of the radio.
Receiver sensitivity, and the maximum output is -70dbm belongs to uv level, so with mv level oscilloscope and frequency meter is
The maximum output is -70dbm which belongs to uv level, so the signal cannot be detected by mv level oscilloscope and frequency meter.
