The North Atlantic 5410C-89-1 is a C-size VXIbus module delivering bidirectional synchro/resolver conversion in a single instrument. It integrates three synchro/resolver to digital (S/D) channels for angle measurement and three digital to synchro/resolver (D/S) channels for signal stimulus, addressing measurement and simulation tasks in a unified platform.
