The pattern generator for calibration of torsional vibration systems, AED8011, is an electronic device intended for the calibration of torsional vibration systems in test benches. It provides standard signals generated with a digital circuit of high precision and stability, allowing to replace those provided by the tachometers used in test benches. The equipment is portable, of small dimensions and with electrical characteristics and connectors equivalent to those of the aforementioned tachometers to allow its direct use in the factory. The standard signals are selected with two pushbuttons on the front panel of the equipment.

The output signal is equivalent to that provided by the LTN Servotechnik GMBH model G58HSIMBI-5000-555-05 rotary increment encoder.
