Regarding http://www.calex.com/pdf/3power_impedance.pdf
At the end there's a schematic for measuring the impedance of a power supply. As I don't have a signal generator (soundcard only goes to 20 kHz), what would be the simplest way to construct a signal generator that goes to a few hundred kHz, sine output?
