Rohde & Schwarz RT-ZPR20 - 2.0 GHz Power Rail Probe

Power Rail Probe

 

• Extra-large offset compensation make the Rohde & Schwarz RT-ZPR power rail probes an excellent tool for characterizing power rails.
• AC/DC Coupling
• High bandwidth
• Very low noise
• High sensitivity

High bandwidth, high sensitivity, very low noise and an extra-large offset compensation make the R&S®RT-ZPR power rail probes an excellent tool for characterizing power rails. An integrated highaccuracy DC voltmeter provides instantaneous DC voltage readout

Up to 4.0 GHz bandwidth and very low added noise

Low voltages with tight tolerances make testing power rails difficult. Not only do newer power rails require more precise low voltage measurements, the rails are susceptible to coupling from high-speed clocks and RF sources. With a bandwidth up to 4.0 GHz, excellent sensitivity due to the 1:1 attenuation ratio and low noise, the R&S®RT-ZPR power rail probes excel at precise ripple measurements. Coupled with the industry’s best spectrum analysis capabilities of the R&S®RTO and R&S®RTE oscilloscopes, the solution also helps users isolate periodic and random disturbances (PARD).

The R&S RT-ZPR20 power rail probe is a specialized oscilloscope probe for very low-noise measurements on power rails. This active 1:1 probe with integrated offset allows you to zoom in on the ripple sitting on top of the power rail voltage. It is compatible with the R&S®RTE and R&S®RTO digital oscilloscopes, adding only 10 % of noise to the oscilloscope for accurate measurement of ripple and noise components. The probe has a 2 GHz bandwidth to see high-frequency transients or unwanted RF signals coupled into the power rail. Due to the slow frequency rolloff, the 2.4 GHz band can be covered with only slightly more attenuation. At 50 kΩ, the probe has a much higher DC impedance than a direct coaxial connection and therefore does not significantly load the power distribution network.
