    Power supply rejection ratio measurement (PSRR)

    Feb. 28, 2020
    Power supply design engineers often face the challenge of measuring the power supply rejection ratio or power supply ripple rejection (PSRR) of their design. The PSRR is an important parameter to indicate the power supply’s output stability.

    Oscilloscopes are the primary measurement tools used today by engineers to test and characterize their power supply designs. The R&S®RTx-K36 frequency response analysis (Bode plot) option provides a low-cost alternative to low frequency network analyzers or dedicated standalone frequency analyzers.
