DSRS & DSRB
Decade Synchro/Resolver Bridges & Standards

Key Features DSRS

100° increment switching to simulate operation over a full 360°
Selective output
No warm-up time
Age or environmental conditions have little effect
Switches good for 100,000 turns

The TEGAM DSRB 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 torque transmitters as components or for simulating an incremental control transformer in a servo loop.

Because of the low output impedance, the bridge is essentially insensitive to pickup and loading errors.
The high input impedance allows an actual load to be connected in parallel with the bridge input, providing a test of the component under actual load conditions.

As with all TEGAM bridges, operation consists of setting in the desired angle -no warm-up, no pre-use calibration. 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.
