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.
The F-CVP-1 consists of 2 concentric metal electrodes. A capacitive voltage divider is formed by the capacitance between the cable bundle under test and the inner metal electrode of the F-CVP-1, and the capacitance between the inner and outer metal electrodes of the F-CVP-1. A Fischer Custom Communications, Inc. proprietary circuit buffers and amplifies the voltage from this capacitive divider, and provides a voltage out of the F-CVP-1 for direct input into a 50 O signal or spectrum analyzer.
The F-CVP-1 meets the critical requirement to minimize capacitive loading of cables under test. If the loading is greater than 5 pico farads the overall impedance of the cable under test can be significantly lowered and result in erroneous common mode voltage measurements.
