- VMEbus Position Output
Data Format:
- Units: fractions of a wavelength
- 2's Complement: 32-bit parallel binary
Positive Logic
- Least Significant Bit (or one count) equals resolution
- Data Rate Over Backplane >100kHz
- Data Age and Sample Ambiguity:
- After a sample operation, the value in the position register will reflect an actual position that occurred 0.1 to 1.4 us before the sample operation was initiated.
Sample Delay:
- The position register may be read 1.5 us after a sample operation.
