Chapter 5 Modulated Waveform

HDG2000B supports AM, DSB-AM, FM, PM, 2ASK, 2FSK, 2PSK, BPSK, QPSK, 3FSK, 4FSK,

OSK and PWM modulations. It can output modulated waveform from a single channel or from two

channels at the same time. The modulated waveform consists of carrier waveform and modulating

waveform. The carrier waveform can be Sine, Square, Ramp, Pulse, Arbitrary waveform (except

DC)

or Harmonic. The modulating waveform can be from internal (default), other channel, or

external modulation source.
