Description
The ISP-16 is an ultra stable, high frequency, analog differential integrator. The period of integration can range from the sub microsecond up to 10 s and is controlled by an external gate. The integrators are standardly packaged in a 1U rack mountable chassis. A number of parameters are factory selectable based on the selected application including the I/O connectorization, the integration RC time constant, and the integrator input impedance.

The ISP-16 integrator measures both extremely small fields and extremely large fields with high precision. For example, if connected to a loop with a 0.1 m2 area (100 turns 3 cm in diameter) wound on ferrite with a relative permeability of 1000, the integrator would produce a 1 mV output when measuring a 100 pT field. When measuring medium to large fields, small air core pickup coils would be used. Since air core coils do not suffer saturation issues, the ISP-16 integrator can measure very large currents, for very long times, without the usual droop and saturation issues encountered when using standard current monitors/transformers. There is no inherent limit to the maximum field size or current that can be measured.
