  • Direct Sampling Rate (DAC 14bit) 2.5 Gigasamples / sec
  • 2 channels: arbitrary-shaped generator channel and functional generator channel
  • RAM 2 GB

MGVCH is designed to reproduce arbitrary waveforms, as well as to reproduce sinusoidal waveforms with amplitude, frequency, phase modulation or without modulation.

MGVCH can be used for research, tuning and testing of systems and devices used in electronics, automation, computer and measurement technology, instrument making.

MGVCH contains two channels independent from each other:

  • one channel of an arbitrary waveform generator (AWG);
  • one channel of the functional generator (AFG).
AWG channel reproduces:
  • Arbitrary analog signals on one output;
  • logic marker signals on two outputs.
Channel AFG reproduces:
  • sinusoidal analog signals with frequency, phase modulation or without modulation;
  • harmonic sinusoidal signals, and various types of modulated signals on one channel by direct digital synthesis
