1 Introduction
The TBCP1-200 is a fixed aperture RF current monitoring probe, expanding the Tekbox
product range of affordable EMC pre-compliance test equipment.
The probe has a 3dB bandwidth of approximately 200 MHz and is characterized and usable
over the frequency range from 10kHz to 500 MHz.

4 Typical transfer impedance table
The table below shows typical transfer impedance data of a TBCP-200 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.
