Tektronix P5122 Active Probe

The Tektronix P5122 probe should not be used on the TPS2000 Series oscilloscopes for AC-coupled measurements on signals with greater than 300 V DC offset.

In many applications, it is important to be able to isolate the measurement from earth ground and also to isolate the common voltage between channels. The P5150 or P5122, coupled with the TPS2000 and THS3000 Series digital storage oscilloscopes, deliver both the isolation for the measurement from earth ground and full isolation between the channels. The Tektronix P5150 is the recommended probe for measuring ripple on high-voltage DC supplies.

A high voltage single-ended probe is typically used for measuring ground referenced signals up to 40 kV. However, some single-ended probes are designed for oscilloscopes with isolated or floating inputs for measurements that are not ground referenced. Users should select probes with a low input capacitance specification (< 4 pF) to minimize the probe’s loading effect on the circuit because a probe with lower input capacitance will offer higher input impedance at higher frequencies.

Safe high voltage probe solutions for ground-referenced voltage testing. It is critical to safely and accurately capture real-time signal information from “elevated” or “floating” voltage systems. Our portfolio of high voltage probes provides the safety you need for single-ended, differential or isolated measurements.
