Introduction:

The CVP 9222C is a high impedance capacitive voltage probe manufactured by Schwarzbeck (Germany) and authorized for sale by EUTTEST (Shenzhen) to test asymmetrical disturbing voltages on the DUT cable without interrupting the DUT power supply.

The probe is equipped with a highly efficient metal shield to suppress external interference and is powered by a high capacity battery with a built-in battery capacity for over 40 hours of continuous operation. The probe's built-in transimpedance amplifier has extremely low noise characteristics and is capable of handling CISPR 16 standard pulses without distortion.

This probe can be used for the CVP conducted emission test method described in the CISPR32 standard, as shown below: Contact EUTTEST for more information about this probe's product pricing, technical specifications, voltage divider calibration, and its detailed CISPR32 standard test description.

Test Utilization Guide

Capacitive voltage probe designed to measure with EMI receiversAsymmetrical interference voltageThe

The typical method of application of the capacitive voltage probe is described in CISPR 22/EN 55022 C 1.3. When the cable diameter is 8 mm, this probe has a transmission coefficient of 34 dB which must be added to the reading of the EM measurement receiver. For other cable diameters, please refer to the chart below to find the appropriate transducer factor.

CVP 9222C Factor Chart for Common Cable Sizes

Factor charts for common cable sizes

Typically, measurements in the frequency range 150 kHz to 30 MHz are made using a quasi-peak or average detector with a bandwidth of 9 kHz. The probe comes with a clamp that can be opened to hold the cable to be measured, and it is recommended that the cable be centered inside the probe as much as possible using the M-shaped plastic pieces on each side of the probe. The probe is equipped with a screw that allows the tester to quickly and accurately adjust the cable position in seconds without additional tools, the larger the cable diameter the more important it is that the EUT cable is correctly centered.

The CVP 9222C comes with a clamp for open clamping of the cable under test.

Self-contained clamp for open clamping of the cable under test

Capacitive voltage probes need to be calibrated for voltage dividing factor, the calibration method is detailed in GB 6113.102 G.2, EUTTEST configures the following list of products for you to calibrate the voltage dividing factor of capacitive voltage probes:
