Output the modulated waves
After pressing the Mod function key, press the F1 key to select the modulation type
to output the modulated waveform. Types that can be modulated include: AM
(amplitude modulation), FM (frequency modulation), PM (phase modulation), PWM
(pulse width modulation), ASK (amplitude shift keying), PSK (phase shift keying), FSK
(frequency) Shift keying), 3FSK (ternary frequency shift keying), 4FSK (quadrature
frequency shift keying), BPSK (biphase phase shift keying), OSK (oscillating keying).
Note: The following output modulation waveform uses CH1 channel as an example.
If you need to set CH2 channel, please refer to CH1 channel specific operation.
Amplitude Modulation(AM)
The output modulation waveform consists of a carrier wave and a modulated wave.
The carrier wave can be a sine wave, a square wave, a ramp wave, or an arbitrary
wave. In amplitude modulation, the amplitude of the carrier varies with the
instantaneous voltage of the modulation waveform. The user interface for amplitude
modulation is shown below.
