- Notes
-
Complex ratio bridge intended for the calibration of synchro resolvers. It generates two sinusoids phase shifted by 90 degrees. Two precision transformer dividers are used to compare the output of synchro resorver windings against the internal quadrature references.
The set uses two ESI 'Dekatran' precision variable transformers, each with four-digit resolution. Due to the use of transformers, its accuracy depends to a great extent upon the turns of each intermediate tap.
12 V internal storage battery. Built-in AC battery charger.
