Benefits of the TekBox TBCP Series Current Monitoring Probes with Fixed Aperture or Snap-on

  • Frequency from 10 kHz to 1 GHz.
  • Apperture radius from 17 mm to 32 mm
  • Max. primary current (RF) 3 A, transfer impedance close to 20 dBΩ.

TekBox TBCP Series RF Current Monitoring Probes

Models TBCP1, TBCP2, TBCP3, TBCP4

The TekBox TBCP1, TBCP3, and TBCP4 series are fixed aperture RF current monitoring probes, the TBCP2 series are snap-on RF current monitoring probes. Depending on the model they cover a frequency range from 10 kHz up to 750 MHz or from 30 kHz up to 1 GHz.

The TekBox TBCP1-CAL, TBCP2-CAL, TBCP3-CAL, and TBCP4-CAL are calibration fixtures for the corresponding RF current monitoring probes. RF current probe calibration fixtures are used in combination with a VNA/vector network analyzer or spectrum analyzer equipped with a tracking generator in order to measure the transfer impedance of RF current monitoring probes.
