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.
High voltage probes white paperPPM Power can also offer custom designs for any applications. Find a product in the tables below or contact a member of our technical sales team on +44 (0)1793 784389.
