V1.0TBBCI1-CAL帝T巨K旦口×DIGITAL SOLUTIONSBULK CURRENT INJECTION PROBE CALIBRATION FIXTURE1 IntroductionThe TBBCI1-CAL is a calibration fixture for the TBBCI1 series of Bulk Current Injectionprobes.The calibration fixture is used in combination with a Vector Network Analyzer or SpectrumAnalyzer equipped with tracking generator in order to measure the transfer impedance orinsertion loss of BCI probes.Every Tekbox RF current monitoring probes is shipped together with a correspondingcalibration 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,incase that a probe dropped and there is suspect that its ferrite core may have suffereddamage.Furthermore,calibration fixtures are used for the calibration of conducted immunity test set-ups.Refer to the Conducted Immunity Basics application note for detailed information on howto use calibration fixtures for this purpose.The application note can be download from theTekbox web-site.2 OperationA calibration fixtures in combination with the installed probe represents a coaxial line with animpedance of approximately 50 Ohm.1
