SW 9606 Current Transformer, shielded, 9 kHz - 200 MHz

The Calibration Jig CA 9608 is used to measure the transducer of current clamps up to 500 MHz acc. to CISPR 16-1-2, MIL-STD-461D or ISO 11452-4. Alternatively, the CA 9608 can be used to characterize ferrite materials (e.g. clamping ferrites, toroids, ferrules) or any other passive disturbance supression components as described in CISPR 17. For calibrations of current transformers, there is additional equipment required, a coaxial termination resistor and e.g. a network analyzer, a spectrum analyzer with tracking generator or a signal generator with a receiver. The calibration fixture comes with two N female connectors, each of them is equipped with a high quality 4 mm banana plug to accept the inner conductor of the fixture. The CA 9608 comes with knurled-head screws at both sides, which allows a fast opening without any tools. This is especially useful for "push-through" current transformers, which can not be clamped or opened. The height of the inner conductor is variable, this provides a wide range of possible current transformer sizes up to 86 mm diameter to be calibrated with a single adapter. A longer inner conductor is available on request in order to calibrate current transformers of up to 90 mm width.

Application:

Typical application example according to CISPR 17 with a ferrite toroid. A S21 measurement is made via the calibration fixture which is equipped with the material under test. The measured S21-data can be used to characterize material properties.

Typical application example with SW 9606 current clamp and CA 9608 calibration adapter. A S21 measurement is made via the current clamp and the calibration fixture with the second port of the fixture being terminated with 50 Ohm
