F-75B Profile:
The F-75B is an EMI monitoring current probe manufactured by FCC (Fischer Custom Communications, Inc.) and authorized for sale by EUTTEST Shenzhen. The F-75B has the advantage of a large 70mm aperture, making it ideal for large cable bundles. The F-75B can be used to measure pulsed currents up to 100 amps with a pulse rise time of 800 picoseconds and a pulse width of 40 nanoseconds. It can operate up to 200 amps DC-400 Hz, 10 amps continuous wave and 100 amps peak pulse current.
The main technical parameters of the F-75B:
Available frequency range: 1 kHz - 500 MHz
Internal ring diameter: 70 mm
External ring diameter: 125mm
Height. 38mm;
Typical ZtΩ(1)1；
