CSP 9160

EMC Emission/Immunity Sensing Probe

CSP 9160zoom
  • As defined in CISPR 16-1-2
  • Suitable for emission measurements per CISPR 16-2-1, CISPR 22 and CISPR 32
  • Suitable for BCI testing per MIL STD-461 and various automotive standards
  • Flat frequency response
  • Ruggedly designed

The CSP 9160 is a broadband RF current sensor probe as defined in CISPR 16-1-2. Beside the compliance measurements of asymmetrical disturbance currents as e.g. required in CISPR 16-2-1 and CISPR 22, the probe can be used in a number of diagnostic applications to measure superimposed RF currents flowing in conductors, or cable harnesses.
A convenient feature of the CSP 9160 is that, from 100 kHz to 120 MHz, it has a flat frequency response with a 0 dB transducer factor, allowing voltage measurements to be read as current, directly without any correction. The probe can be easily and quickly clipped around the cable under test and the RF currents measured using an oscilloscope, spectrum analyzer, or EMI receiver. Its large aperture (25.4 mm) can accommodate most cables and can handle power lines with currents up to 50 amps.
