Fisher Capacitive Voltage Probes
In accordance with CISPR 32, Fischer Custom Communications, Inc.'s non-contact capacitive voltage probe (F-CVP-1) measures the common mode voltage appearing between a multi-pair balanced cable bundle and its local ground reference. To perform this voltage measurement, the F-CVP-1 does not require direct contact with the metallic conductors in the cable bundle, nor does it require the physical breaking of the cable bundle to complete the installation.
