TBPCP1-20100
RF PULSE CURRENT MONITORING PROBE
Introduction
The TBPCP1-20100 is a RF pulse current monitoring probe, expanding the Tekbox product range of affordable test equipment.
The probe has a very flat response from 20 Hz to 100 MHz and is characterized over the frequency range from 1 Hz to 200 MHz. The TBPCP1-20100 is typically used for surge or RF pulse current monitoring applications in the time domain, in contrary to RF current monitoring probes designed for EMC applications, which are typically used for measurements in the frequency domain.
The aperture of the RF current monitoring probe is 25 mm. Its transfer impedance is -20 dB Ohm with a typical 3dB bandwidth from 20 Hz to 100 MHz.

Transfer impedance
Typical transfer impedance table
The table below shows typical transfer impedance data of a TBPCP1-20100 pulse current probe. Each current probe is delivered with its corresponding measurement protocol. The transimpedance is given for a 50 Ohm load.
Transimpedance [V/A] = 10^(dBOhm/20) @ 50 Ohm
Transimpedance [V/A] = 2*10^(dBOhm/20) @ High Z
