Synchro Standard

The A202S5 Synchro Standard is a unique instrument that makes available a greatly-simplified, extremely precise technique for testing and calibrating synchro systems and components to absolute accuracies of the order of 0.001%. It eliminates at least three and as many as five sources of error normally encountered in such measurements, at the same time significantly reducing the equipment end time required to perform those tests. Angular range of 0 to 360 in 5 increments. Nominal input of 26 V, 400Hz.


This Synchro Standard is in great shape.  The build quality on these is incredible.  With heavy duty machined chassis and beautifully routed and harnessed wiring, they border on art.
