TEKBOX TBCP2-500 – 32mm Snap-On RF Current Monitoring Probe
Introduction
The TBCP2-500 is a snap-on RF current monitoring probe, expanding the Tek box product range of affordable EMC pre-compliance test equipment. The probe has a flat response with a 3dB bandwidth of 500 MHz and is characterized over the frequency range from 30kHz to 600 MHz. Upon request, the test protocol can be extended to frequencies down to 1 kHz.
The aperture of the RF current monitoring probe is 32 mm. Its transfer impedance is > 15 dB Ohm in the range from 1 MHz to 500 MHz.

Transfer impedance
Typical transfer impedance table
The table below shows typical transfer impedance data of a TBCP2-500 current probe. Each current probe is delivered with its corresponding measurement protocol. This data can be used for the creation of a correction file for EMCview or similar EMC measurement software. The transfer impedance in dBΩ subtracted from the analyzer reading in dBμV gives the corrected reading in dBμA. Refer to the application notes of EMCview on how to create a current probe correction file.
