The F-32-9B has an aperture which will accept a flat, ribbon or multiple conductors molded into a flat cable. Dimensions of the aperture are 6.35 mm high by 152.4 mm wide. The sensor is capable of performing with pulse currents of 100 amperes having a duty cycle of 0.001 and 100 amps of DC to 400 Hz powerline current. The probe has a usable frequency of 10 kHz to 300 MHz. The flat region of transfer impedance is approximately 3W from 10 MHz to 300 MHz.
