Signal and power integrity

Signal and power integrity

Stable and clean power rail signals are the basis for a proper performance of any electronic design. Rohde & Schwarz provides a wide range of benchtop and handheld test solutions for Power Integrity testing.

Signals traveling through electronic designs typically get degraded by crosstalk, bandwidth limitations and signal line discontinuities. Take a look at our comprehensive solutions to measure e.g. timing, jitter, return and insertion loss, eye diagram, crosstalk and unwanted signal components.

Signal integrity

Power supply rejection ratio measurement (PSRR)

The PSRR is an important parameter to indicate the power supply’s output stability. It provides information about the influence of input voltage variations on the stability of the output voltage.
