The SW 9605 Current Clamp was designed to measure RF-currents on conductors or conductor bundles with a maximum diameter of 23 mm. The conversion ratio is 1:1 in the nominal frequency range, therefore the receiver-reading in dBµV corresponds directly to the current in dBµA. This corresponds to a transfer-impedance of 1 Ohm or an insertion loss of 34 dB in the 50 Ohm system. The clamp can also be used below the nominal frequency range, in this case the transducer of the diagram has to be considered. Above 30 MHz the clamp can be used up to 80 MHz with slightly increased measurement uncertainty.
