Capacitive Voltage Probe

The Fischer Custom Communications, Inc. non-contact capacitive voltage probe (F-CVP-1) is used to measure the common mode voltage appearing between a multi-pair balanced cable bundle and the local ground reference for the cable bundle in accordance with CISPR 22 Section C.1.3. The F-CVP-1 makes this voltage measurement without requiring direct contact with the metallic conductors in the cable bundle, or requiring physically breaking the cable bundle to install the F-CVP-1.
