Model DSRB-5CDA-4, 400Hz, Decade Synchro Resolver Bridge combines the functions of a decade synchro bridge and a decade resolver bridge into a single unit. A front panel switch changes the unit from one mode of operation to the other. The units are designed for testing control transmitters, differentials (rotors), and torques transmitters as components or for simulating an incremental control transformer in a servo loop.
The unit is essentially a decade resolver bridge. In the synchro mode, the three wire input is converted to two voltage signals in a Scott-Tee transformer arrangement. After conversion, the voltage comparator operates in the same manner as in the resolver mode.
For use in testing autopilot systems, aircraft indicators, and servo loop response. As a synchro standard, the unit is used to test CDX's, CT's, TDX's, TDR's and TR's. As a resolver standard, the unit may be used to test RD's and RC's.
