With an internal aperture of 38.1 mm, the I-150 series bridges the gap between the I-125 series (ID = 31.75 mm) and the much larger I-262 series (66.5 mm).
The I-150-1HF is the first probe to be offered in the new housing and has similar performance characteristics to the high frequency I-125-1HF probe. It has a transfer impedance of 5 Ω and bandwidth from 1 kHz to 1 GHz (usable frequency range 50 kHz – 1 GHz).
This new I-150 housing will be offered for other current probes designs.
