The F-65A is for laboratory and fi eld testing. It is capable of measuring
pulse transients with risetimes of 200 picoseconds and a pulse width of 3
microseconds. This probe has a small outer diameter, approximately 71 mm
with an internal diameter of 32 mm. Its transfer impedance is 0.1 Ω from 100
kHz to 1 GHz. It can operate up to 350 amperes of DC – 400 Hz, 10 amperes
of CW and 100 amperes of peak pulse.
