||Abnormal slit detection
Rotational jitter evaluation and transient analysis are made by continuous measurement of the period or time interval of the pulse from an encoder fixed to the motor.
In the encoder evaluation all pulses, both phase A and phase B, from all slits of the encoder need to be measured.
Because the TA320 makes continuous measurements, the positive and negative pulse widths can be evaluated at the same time. Abnormal pulse widths are easily detected.
The TA320 Time Interval Analyzer is an instrument which can measure the period, pulse width and time interval of a signal continuously at a maximum rate of 14 MS/s with a maximum resolution of 100 picoseconds. The large liquid crystal display panel is equipped with a touch-sensitive screen, enabling an intuitive, smooth operation in measurement and data analysis. A high screen-update rate allows the immediate display of analysis results.
