Current probes are calibrated through the use of a calibration fixture which provides a 50Ω coaxial-type transmission line arrangement. The fixture allows the probe to be clamped around the center conductor, while the outer conductor encapsulates the probe on four sides, so that the transmission line characteristics are not compromised.
FCLCE-1000 Calibration Fixture (optional) is specifically designed to provide a nominal 50Ω transmission line for the CLCE-400. The fixture is required for calibration of the Transfer impedance, insertion loss and VSWR parameters.
