With R&S RTO-K31 and R&S RTM K31 power analysis options, oscilloscopes can automatically test quality of all segments of switching power supplies, including mains voltage quality of input range, safe operating area of switching transistor, as well as magnitude and spectrum of output ripple. For power supplies with high clock frequencies, R&S RT ZD10 active differential wideband probe combines high bandwidth of 1 GHz with input voltage range of 70 Vdc or 46 Vac peak.
