ETS-Lindgren’s Model 94111-1 Current Probe is capable of making bulk current injection measurements up to 1 GHz. The 94111-1 is a RF sniffer probe for cable common mode current sources of radiated emissions and as measurement of cable common mode coupled currents during radiated susceptibility testing.
The 3.18 cm (1.25 in) window makes the 94111 series probes suitable for measurements on most power cables (AWG 4/0 cable, good for several hundred amps, is 12.7 mm (0.5 in) diameter, exclusive of insulation). Probe saturation current is compatible with the current carrying capacity of wires placed in its window.
