The F-75 is usable from 10 kHz to 500 MHz and has a transfer impedance of 1W (±3 dB) from 700 kHz to 500 MHz. It can be used to measure pulse currents up to 100 amps in magnitude with 800 picosecond risetimes and pulse widths of 40 nanoseconds. The probe has the advantage of being equipped with a large aperture of 70 mm.
