In Reply to: " it would be useful if we could see a spectrum analysis of the power supply's noise " posted by beppe61 on July 13, 2016 at 22:49:36:
There are some possibilities to do similar measurements at a fraction of the cost, with a computer + soundcard + software (for instance, look for Spectraplus.com)
And, of course, enough knowledge about electricity
But, by no way you will get enough bandwith to comply with the 20 MHz requirement from the Keysight/Agilent/HP Application note
Which is advertisement directed toward the industry/laboratories, widely exceeding what would really be useful for average audiophiles
Except those who use switching power supplies, switching power amps, high definition digital sources, etc.
