Power Rail Probe

Power Rail Probes are active voltage probes with built-in offset capability. They acquire low-voltage DC power rail signals and displays small rail voltage variations with high sensitivity, low noise, and low circuit loading.

Explore Active Voltage Rail Probes

Large offset range

+/-60 V offset permits the DC signal to be displayed in the vertical center of the oscilloscope grid even at high-sensitivity gain settings. It has a maximum +/-800 mV dynamic range.

Low attenuation and loading

Active Voltage Rail Probes has a nominal 1.2x attenuation for minimum noise. 50 kΩ impedance using the 50 Ω input effectively eliminates rail loading.

Assortment of tips and leads

A wide assortment of standard tips and leads makes it easy to connect to multiple probing points. Optional hand-held browser available.

The Impact of Power Rail Noise on Clock Jitter

Noise on the power rail may not only create bit errors due to voltage spikes, but it may also increase clock jitter. Clock jitter is an insidious source of noise difficult to debug. In this webinar, we demonstrate how to measure the jitter in both clocks and data and identify the contribution from noise on the power rail. These techniques can be applied to any system in which minimizing clock and data jitter is important.
