Solid State Active Synchro Control Differential Transmitter
-
Computer Conversions Corporation
The input is transformer isolated and accuracy applies over the operating temperature range and with +/-10% input amplitude and frequency variations. The operational amplifier outputs are not transformer isolated, and can be driven into external power amplifiers and Scott "T" transformers for 3 wire synchro outputs. A typical application of this series is in a conventional positioning servo system as a complex error processor. The use of the solid state CDX makes possible the design of servo systems that can be digitally programmed by direct computer input to the digital input of the SCDX.

RF Filters
-
RF Filters block unwanted frequencies when testing electronic devices for emissions during EMC testing. They attenuate unwanted frequencies and allow the desired signals through. The RF filters isolate the device under test from external RF noise, this increases the reliability and accuracy of the EMC testing by preventing out-of-band noise and harmonics.
