A remarkably convenient operator interface with performance found only in the best units available make the SC-121 ideal for controlling electrodynamic shakers in almost any test situation from research and calibration to production testing.
- Dual microprocessor design
- Digital signal synthesis and filtering
- Two-channel acceleration input and control
- Flexible programming with non-volatile memory
- Four independent meters display all control parameters
- Analog data outputs interface easily to computer analog inputs and x-y recorders
The servo provides an output that will give a constant displacement and or acceleration level during a swept or stationary sine test by means of an acceleration feedback signal.
Performance:
Two independent input channels with built-in conditioning amplifiers. The built-in input amplifiers have a current source and adjustable sensitivity. Three separate digital meters monitor frequency, acceleration and displacement. Test cycle counter displayed on frequency meter upon demand.
Control modes: channel 1 or average (channel 1 and channel 2).
Output modes: Log channel 1 accel., Log channel 2 accel., Log average accel., linear difference ratio.
Convenient user interface: requires little or no documentation to set up or run.
Three program storage in internal nonvolatile memory for easy recall of frequently used tests. Analog and TTL inputs and outputs allow the controller to function with either a PC or other test control or recording instruments.
