描述

The Keysight 10895A VMEbus laser axis board supplies ultra-precise position (or distance) information for use in dimensional measurement and motion control system applications. The register-programmed position axis board provides a real-time hardware position output in 32-bit format. The output position is also readable over a VMEbus backplane.

As part of a Keysight VMEbus laser interferometer positioning system, the Keysight 10895A offers a high-performance solution for IC manufacturing, precision machining, and custom staging applications. The exceptional accuracy of the laser system allows the precise positioning and motion control required for consistent end-product production and quality.

 

 

  • 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.
  • P2 Connector Hardware 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 Update Rate:
  • Keysight 5517A: 1.5-2.0 MHz
  • Keysight 5517B: 1.9-2.4 MHz
  • Keysight 5517C: 2.4-3.0 Mhz
  • (Hardware included to synchronize to slower clocks)
  • Data Age:
  • Keysight 5517A: 2.1-4.1 us
  • Keysight 5517B: 1.8-3.3 us
  • Keysight 5517C: 1.5-2.7 us
  • Data Age is dependent on the laser head reference signal (split-frequency) and by knowing exactly when, in relation to the rising edge of the Error Clock, the Position Error lines are sampled -- call this time deltaT. Data Age = ((0.34 us + delta T us)+(4.0 +/- 0.5) / (Reference in MHz)(us)) Additionally, the Data Age may vary up to 0.1 us typically and up to 0.25 us in a worst-case situation as a result of the reference frequency varying over time.
