Hello,
I would have a question related to a specific requirement we have for a pulse (square signal) generation in terms of noise.
We want to generate a square signal to bias a detector, therefore we need the signal to have very low noise in the high and low levels (i.e. in the flat parts; we will sample the square signal when it is high and low, and the sampled signals should have a noise spectrum below 2e-13 V^2/Hz at 1Hz and above. In terms of square signal frequency, we will work below 100kHz (pulse repetition rate); the amplitude of the square signal should be tunable in the range +- 10V.
Do you think this would be feasible with a waveform generator? Or would you recommend any other way of generating such a signal? Usually signal generators are specified in terms of phase noise or jitter, but this flat part noise is not always given (or cannot always find it).
Thanks a lot for your help!
John

Re: Signal generator noise
The 2600B family of System Sourcemeters can produce user definable pulses using the trigger model.
The 2600B datasheet gives typical noise specs for each voltage source range.
