CVP 2200A

Capacitive Voltage Probe

CVP 2200Azoom
  • CISPR 22 (EN 55022), CISPR 32 (EN 55032) and CISPR 16-1-2 compliant
  • Battery or DC power supply
  • Switchable conversion factor
  • Shielded to reduce the direct capacitive coupling from local cables
  • Calibration fixture included

The Capacitive Voltage Probe (CVP) is designed for measuring asymmetrical disturbances on cables with capacitive coupling principle. It gives the opportunity to do the measuring without disconnection of the tested cable (“in-situ”) and it avoids the influence of the transmission. Main parameter of the CVP is the coupling factor, measured in a calibration system with 50 Ω impedance. The capacitive voltage probe is specified in chapter 5.2.2 and Annex G of CISPR 16-1-2.
