ITR Passive integrators are designed to use derivative sensors, such as field or current probes, to measure fast pulsed signals. Connected to this type of sensor, the passive integrator produces an overall flat response without the drawbacks of the numerical integration. The output of the passive integrator shall be connected directly to the high impedance input of a fast rise-time measurement device or of a 1 MΩ to 50 Ω impedance matching device.
