Power Supply with Noise Source

Question asked by danren on Jun 7, 2015
Does the Keysight line of power supplies include any models that have a noise injection function? I am needing to test a system's susceptibility to noise on the power supply, and would like to be able to inject the noise directly at the power supply outputs. I know that I could accomplish this with an Arbitrary Waveform Generator coupled into the power supply lines, but would much prefer a single instrument that gives me this capability. The power supply for this application would need to be able to supply 28 VDC, with periodic spikes of up to +/- 5 VDC, at frequencies below about 30 kHz. Any information would be appreciated.
