Comprehensive example
First make the instrument run in frequency modulation (FM) mode, and then
set an internal pulse wave of 2kHz as the modulation signal and a sine wave
with frequency of 10kHz and amplitude of 100mVpp as the carrier signal.
Finally set the frequency deviation to be 5kHz. The specific steps are as follows:
1) Enable frequency modulation (FM) function
Press the Mode button, and move the cursor to FM by the
key,
OK to enable FM.
press
2) Set modulation signal parameters and waveform
Follow step 1), press the OK key and use the numeric keypad to enter 2,
then select the parameter unit and press the button .

3) Set carrier waveform and parameters
Press the STD/MOD soft key, the STD is selected, then press (default
sine wave) to select the sine wave as the carrier wave.

Press Freq to set the frequency, use the numeric keypad to enter 10, then
select the parameter unit .
Press Ampl to set the amplitude, use the numeric keypad to enter 100, then
select the parameter unit .
Short press the Output button, if the backlight is on, it indicates the channel
output is enabled.
The FM modulation waveform is shown below:
