High Voltage Probes & Attenuators

PPM Power offers high voltage, high bandwidth voltage probes and coaxial HV attenuators.

High voltage probes and dividers are designed for use with oscilloscopes and meters with >1 MΩ input impedances. They are suitable for DC, 50 Hz AC, or pulsed measurements. The attenuators are suitable for measurement in 50 Ω systems, with very fast rise time pulses.

Two high voltage probe technologies are available: compensated resistive dividers for general DC and AC high voltage measurements and capacitive voltage dividers for AC only.
