OPU SERVO ANALYZER |
| MODEL 4501 | |
|
|
| The MODEL 4501 is Servo Analyzer used for Optical Pick up for optical disc (OPU) to check [observe] the characteristic of Focus/ Tracking servo in actuator performance. This equipment is capable of connecting to Servo Unit made by ACT or to which a connecting terminal for Servo Analyzer is provided. |
| This Servo Analyzer is available for reducing its measuring time, and the measurement result shows [is indicated] [displayed] on the external LCD monitor. In addition, the function of GO/ NG judgment is also provided. |
| This MODEL 4501 is available for the production line to judge the variation [fluctuation] of phase characteristic which occurs in [caused by] resonance [vibration] of actuator. And also the adjustment for OPU, by connecting a bar cord reader to it, the measured data and two dimensional bar cord labeled on OPU are read and saved in SD memory card. This equipment corrects these original data used for checking rejected product and quality control. | | |
