Unitronix announce the 5330A, a rack mount/bench-top programmable synchro / resolver simulation instrument featuring integrated touch-screen controls and input terminals. This second generation simulator from North Atlantic Industries (NAI) represents a major step forward by using digital technology to produce synchro and resolver outputs. Improved flexibility is provided by two fully independent outputs that can be used to simultaneously simulate two separate synchro or resolver signals, or can be combined to operate as two-speed outputs. The versatility of this device has been substantially increased by incorporating dynamic modes that enable the user to test servo systems under various simulated stringent field conditions.
