Reasonable memory size for an Arbitrary Waveform Generator?

[egonotto]

Hello,

How much memory is reasonable for an Arbitrary Waveform Generator?

Is it useful to have memory in MB range or are some kB in most cases enough?

Best regards

Depends completely on what you want to do. Since the waveform tends to be looped around on every cycle you don't need a lot of points to get a good looking waveform.

Just reproducing something like a rectified 50Hz AC waveform is KB of memory. Playing back a complex modulated Q I data stream might need many MB
