Accurately measure ripple and PARD

As power rail tolerance levels get smaller, it becomes

increasingly difficult to measure power ripple accurately.

The inherent low noise of the R&S®MXO4 series enables

accurate power integrity measurements on the millivolt

level. The fast update rate of the R&S®MXO4 series allows

you to quickly see infrequent and worst-case ripple as well

as periodic and random disturbance (PARD) anomalies.

Debugging and validating power rails

POWER INTEGRITY

Measuring small voltages riding on large DC offsets

With the ±60V offset compensation range, the

R&S®RT-ZPR power rail probes allow you to focus on small

ripples on the power rail’s DC voltage. Whether you need

to zoom in on a 1V or much higher DC level, the probe

provides the required offset while maintaining lowest ver-

tical scale settings. Together with the superb low noise

frontend of the R&S®MXO4 series oscilloscope and the

18bit vertical resolution, this combination provides accel-

erated insight into the power integrity of your design.

Power rail characterization with high fidelity probes

Wide bandwidth, high sensitivity, very low noise and extra-

large offset compensation make the R&S®RT-ZPR an excel-

lent probe for characterizing power rails. With a bandwidth

of up to 4GHz, excellent sensitivity due to the 1:1 attenu-

ation ratio and low noise, the R&S®RT-ZPR excels at pre-

cise ripple measurements. Coupled with the oscilloscope’s

powerful frequency analysis capabilities, the R&S®RT-ZPR

probes can be used to isolate periodic and random distur-

bances (PARD). An integrated high-precision, 18bit DC

voltmeter provides an instantaneous DC voltage readout in

parallel.

Find coupled sources with fast spectrum

With the industry’s most capable spectrum, you can see switching characteristics or quickly scan for sources coupled

onto the power rail. The R&S®MXO4 series oscilloscope spectrum algorithm allows you to analyze the spectrum inde-

pendently of the time domain settings. This quickly provides a comprehensive picture of your power rails.
