    Oscilloscope

    this should be ok for checking caps in circuit right?

    i think i need to RTFM

        10MHz BW? P/S PARD (ripple and noise) specs are usually specified assuming a 20MHz BW. That said, the P/Ss and VRMs should have switch frequencies of under 1MHz (P/Ss using transistors as switching devices are probably <50KHz), so 10MHz BW is easily sufficient for detecting switch frequency ripple or oscillation due to elevated ESR. Fluke has some nice 60MHz handheld scopes (190 series) for under $2,000USD.

        Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.
