10-, 12-, OR 14-BIT SYNCHRO-TO-DIGITAL OR RESOLVER-TO-DIGITAL CONVERTER

Description:

The SDC-630/632/634 series are low cost, low profile Synchro-to-Digital (S/D) and Resolver-to-Digital (R/D) tracking converters with standard pin configurations. They use a unique control transformer algorithm that provides inherently higher accuracy and jitter-free output. Utilizing a type II servo loop, these converters have no velocity lag up to the specified tracking rate, and output data is always fresh and ontinuously available. Each unit is fully trimmed and requires no adjustment or field calibration.

APPLICATIONS

These converters may be used wherever analog angle data from a synchro or resolver must be rapidly and accurately converted to digital form for transmission, storage or analysis. Because these units are extremely rugged and stable, and meet the requirements on MIL-STD-202E, they are suitable for the most severe industrial, commercial and military applications. Military ground support and avionics uses include ordnance control, radar tracking systems, navigation and collision avoidance systems.
