Digital / Synchro Converter
Synchros are transformer-type voltage/current transducers that convert a shaft or other rotating device's angular position and/or velocity to a multi-wire AC electrical signal. Both deliver signals proportional to the Sine and/or Cosine of the shaft angle. A Digital-to-Synchro simulator is used to convert digital angle/velocity commands to corresponding Synchro/Resolver AC signals.

Synchro/Resolver to Digital Converters
-
Resolvers and synchros are transducers that convert the angular position and/or velocity of a rotating shaft to an electrical signal. Both deliver signals proportional to the sine and/or cosine of the shaft angle. A resolver-to-digital or synchro-to-digital converter converts these signals to a digital output corresponding to the shaft angle and/or velocity. ADI’s family of RDCs and SDCs offer solutions for these applications.

Clarke-Hess Communications Research
The Model 515 High Accuracy AC Reference Generator fills a need for a relatively low cost and practical solution for supplying a reference excitation to typical LVDT and Synchro/Resolver transducers. The Model 515 has built-in load sensing which, in effect, yields "zero" output impedance and virtually eliminates the effects of fluctuating output loads. With up to 15 VA of output into loads with as much as 80 of phase shift, the Model 515 is ideally suited to driving inductive loads.
