IPC's current monitors are wide band current transformers that measure ac or pulse currents with an oscilloscope or other voltage-sensing instrument. By passing the current-carrying conductor or charged particle beam through the monitor opening, the monitor will sense the associated magnetic field and accurately measure the current without requiring a direct connection. IPC's current monitors convert the primary current into a proportional voltage signal, which is then displayed on the scope or voltmeter.
IPC's wide band monitors are available over a wide range of sensitivities, currents, and frequencies: from 0.01mV/amp to 10V/amp, from micro-Amperes to Mega-Amperes, and from 30 milli-Hertz to 100 Mega-Hertz.
Magnetically coupled current monitors can read currents to very low frequencies but are intrinsically incapable of reading DC currents. Consequently, any DC currents will not be displayed on the scope, and repetitive unipolar pulses will appear on both sides of the zero line. Positive pulses will have a negative baseline and vice versa.
