Arbitrary Waveform Generator (Arb) or dual arbitrary waveform generator.
The dual arbitrary waveform generator is designed to provide optimized
I and Q signals to the signal generator's I/Q modulator. It consists of
three major blocks:
Waveform memory - sampled representation of the waveform
Sequencer - Controls waveform memory play back
Analog signal processing - digital/analog convertors
(DACs) and reconstruction filters
