The first ready-to-use instrument for quantifying magnetic field transients. The FDI2056 fast digital integrator is the world’s fastest and most sensitive voltage integrator. Simply connect a detection coil to quickly measure low-level magnetic field disturbances, such as eddy currents in a switched magnet.

Equipped with a high-speed analog-to-digital converter (ADC), a high-resolution clock, and a highly optimized digital integrator, the FDI2056 achieves a maximum of 500,000 partial integrals per second and provides resolutions up to 10-14 Vs with a precision of 10 ppm.

The FDI2056 is based on two decades of experience in building the world standard for precision integrators, the PDI5025. Building on a design licensed from the European Organization for Nuclear Research (CERN), the FDI2056 brings major improvements such as improved temporal resolution and trigger rate; synchronized acquisition across multiple channels; hardware-optimized digital integrator; and large onboard buffer memory.
