High Voltage Probes

The H6 High Voltage Probe is what we use to calibrate our own modulators. It can measure up to 60kV pulsed and 50kV DC. Output is 1V/10,000V. The probe has one circuit for pulse measurements and another circuit for DC measurements with our own design to linearize the crossover. We calibrate for both scenarios. Test tools are calibrated by certified labs to ensure the final unit is based on NIST standards.
