F-55 Current Probe

The F-55 is usable from 10 kHz to 500 MHz and has a typical transfer impedance of 1W (± 3 dB) between 700 kHZ to 500 MHz. It can operate without saturation from 100 amps peak pulse and 3 amps CW. It is capable of measuring pulse transients with risetimes of 800 picoseconds and a pulse width of 35 nanoseconds.
