F-73 Current Probe

The F-73 monitor probe can be used from 10 Hz to 30 MHz and has a typical transfer impedance of 2W (±3 dB) from 10 kHz to 30 MHz. It can operate without saturation from 350 amps primary current at 400 Hz and 200 amps CW. The F-73 is particularly useful in making conducted emissions measurements on high amperage powerline cables.
