Product Specification Sheet
Overview:
The DA-2KI is a dual channel, Cesium Magnetometer Interface card designed for a PC, ISA bus. This unit provides power to two (2) independent Mag's using a coax cable per channel. The returned signal frequency is inductively coupled, filtered and shaped into a TTL compatible output.
