Numerical stepping modify the selection of project: arrow keys
Caution:
Input power is prohibited, once you input more than 0dbm power you will burn out this signal source, damage caused by input power is not covered by warranty.
Intercom signal source description
Signal source mode:
First row left Frequency (0.5-470M) , right Output power (-70 to -132dBm)
Second line left Subtone (50.0-280.0Hz any analog sub-tone and 105 groups of digital sub-tones) right Modulation tone modulation system (0-3K) (0k is off modulation tone)
Numeric keys: direct input for cursor-pointed items
Up and down keys: step to adjust the value of the cursor pointing item
F1 key: cursor pointing to move
F2 key: backspace key
F3 key: Function key When the cursor is pointing to the output power, sub-tone or modulation tone, it is a cycle switch function, e.g., when the cursor is pointing to the power output, the function of this key is a 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 for 88.8Hz.
Now if you use the up and down keys to adjust in steps of 0.1Hz, if you need to adjust to the standard 50 groups of sub-tones, you have to input 0, 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 digital sub-tone code and then press F3 Example 023 Input 0, 2, 3 and then press F3 to set it up successfully, press F2 to switch between I and N of the digital sub-tone, and adjust the up and down keys to add or subtract from the 105 groups of digital sub-tones.
Entering 0 for the value of modulating tone and sub-tone is equivalent to turning it off.
Step Frequency Setting: When the cursor is pointing to the frequency, long press F3 the current displayed frequency is saved as step frequency.
Quickly input integer frequency: Example input 4, 3, F3 is 430.0000
Special Note:
This signal source is mainly used to test the sensitivity of analog walkie-talkie, belongs to the narrowband FM mode, is not suitable for testing the reception sensitivity of the radio, and the maximum output is -70dbm belongs to the uv level, so with the mv level of the oscilloscope and the frequency meter can not detect the signal.
Package included:
1Pc x 0.5Mhz-470Mhz RF Signal Generator Meter Tester
