Synchro/Resolver Simulator, Programmable

5330A Synchro/Resolver Simulator is a rack mount or benchtop instrument featuring integrated touch screen controls and input terminals. This model represents a major step forward as it uses digital technology to produce Synchro and Resolver outputs. Improved flexibility is provided by two fully independent outputs that can be used to simulate two separate Synchro or Resolver signals simultaneously, 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 servo systems to be tested under various simulated stringent field conditions.

Each channel can be independently programmed for specific dynamic mode operations, including rotation (continuous or start-stop), sine, and square and ramp. In addition, IEEE-488, USB, and Ethernet interfaces have been added to extend remote operation capabilities. As an option, a programmable 6 VA internal reference supply can be specified.

This self-calibrating unit is furnished with factory installed rubber feet and foldaway tilt stand, and can also be installed in a 3.5” half rack slot. Using optional rack mounting brackets, the 5330A can be installed as a single unit in a full rack slot, or as a tandem mount of two units in a full rack slot. It is ideally suited for defense, commercial aerospace, and industrial applications.
