TekBox TBCP1-150 RF Current Monitoring Probe

The TBCP1-150 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 150 MHz and is characterized and usable over the frequency range from 10kHz to 250 MHz.

The aperture of the RF current monitoring probe is 25 mm. Its transfer impedance is > 14 dB Ohm in the range from 100 kHz to 150 MHz.

RF current monitor probes can measure common mode antenna currents that flow on cables or wires. A faultily filtered or manufactured cable could cause a radiated emissions failure at a certified EMC lab or testing facility.  To prevent this wasted expense and time, an RF current monitor probe can ensure EMC compliance before formal testing. The probes measure current by placing a conductor, which carries the current, within what is referred to as the “sensing” window of the probe, and then connecting the probe’s output voltage to a spectrum analyzer.
