3.1.4 ASK (Amplitude Shift Keying)

ASK is a digital amplitude modulation, it expresses digital signals "0"and "1"by changing the amplitude of carrier
signal. And according to the logical of modulation signal to output the carrier signals with different amplitude. The
modulation modes for each channel are independent, it can set the same or different modulation modes to each
channel.
Select ASK modulation
Tap CH1→Modulate→ASK to turn on ASK modulation, the instrument output the moduluated waveform according
to the current setting of the modulation wave frequency and the carrier wave.
Select the carrier waveform
The carrier wave of AM: sine, square, ramp, pulse and arbitrary wave (except DC), the default option is sine wave.
After select ASK modulation, tap Base to present the carrier waveform on the right side.
