The TBCP4-250 is a fixed aperture RF current monitoring probe, it has a very flat response with a 3dB bandwidth of 250 MHz and is characterized and usable over the frequency range from 10kHz to 250 MHz. The aperture of the RF current monitoring probe is 32 mm. Its transfer impedance is close to 14 dB Ohm in the range from 400 kHz to 250 MHz.

The TBCP4-500 is a fixed aperture RF current monitoring probe, it has a very flat response with a 3dB bandwidth of 500 MHz and is characterized and usable over the frequency range from 10kHz to 500 MHz. The aperture of the RF current monitoring probe is 32 mm. Its transfer impedance is close to 16 dB Ohm in the range from 400 kHz to 500 MHz.

The TBCP4-750 is a fixed aperture RF current monitoring probe, it has a very flat response with a 3dB bandwidth of 750 MHz and is characterized and usable over the frequency range from 10kHz to 800 MHz. The aperture of the RF current monitoring probe is 32 mm. Its transfer impedance is close to 20 dB Ohm in the range from 400 kHz to 750 MHz.

Tekbox supplies a calibration fixture corresponding with the TBCP4 series of fixed aperture current probes.
