Current injection Probe Calibration Fixture
The TBBCI1-CAL is a calibration fixture for the TBBCI1 series of Bulk Current Injection probes.
The calibration fixture is used in combination with a Vector Network Analyzer or Spectrum Analyzer equipped with tracking generator in order to measure the transfer impedance or insertion loss of BCI probes.
Every Tekbox RF current monitoring probes is shipped together with a corresponding calibration sheet containing the insertion loss and transfer impedance values vs frequency.
Calibration fixtures can be used for periodic inspection of the probes or for health checks, in case that a probe dropped and there is suspect that its ferrite core may have suffered damage.
Furthermore, calibration fixtures are used for the calibration of conducted immunity test setups. Refer to the Conducted Immunity Basics application note for detailed information on how to use calibration fixtures for this purpose.
