SIM-31200 DDC Generator


The SIM-31200 is a generator from DDC. A signal generator is a device that creates electronic signals, repeating or non-repeating, in the digital or analog domains, depending on need. Signal generators design, test, troubleshoot, and repair electronic devices across many different industries and applications.

Additional Features:

  • 5 VA Drive Capability
  • High Accuracy: ± .003° No Load; ± .008° Full Load
  • Wideband: 47 Hz to 11 kHz
  • Programmable output standard Synchro and Resolver levels
  • Overload Protected
  • Digital Calibration for improved maintainability

The Data Device Corporation SIM-31200 is a high quality synchro and resolver simulator, which incorporates microprocessor control of digital input multiplexing, front panel display, internal 20-bit digital to resolver converter and status/fault flag outputs. The internal 20-bit binary converter provides resolution of .001° BCD or .00034° binary, with accuracy up to ±.003° (10 arc seconds). The angle input may be entered locally via the keyboard, or remotely through the rear panel parallel data connector. The remote input format (BCD or binary) is selectable via a rear panel switch. An optional IEEE-488 interface is available for using the SIM-31200 with instruments connected to a General Purpose IEEE Parallel Data Bus.

The front panel keyboard is for local programming of output formats, increment/decrement, output voltage levels, angle entry and calibration/test functions. The reference input (26 or 115V rms) is broadband (47 Hz to 11 kHz) and may be supplied to the rear panel connector or front panel terminals.

The outputs are transformer isolated synchro or resolver signals programmable to 11.8, 26, or 90V rms line-to-line.

The microprocessor provides control for analog signal output formats and levels. In addition, the microprocessor works in conjunction with a nonvolatile memory and a counting circuit to measure the reference frequency which is used to generate a digital correction and calibration scheme. The SIM-31200 is powered by 115V or 230V rms, and has internal EMI/RFI filtering.

Applications for the SIM-31200 includes production testing, quality control inspections and laboratory instrumentation. Due to its I/O flexibility, the SIM-31200 functions well for testing navigation equipment, antenna position and calibration systems.
