RPI20 parallel interface

The RLE system directly produces a 1 Vpp sine / cosine output with signal periods of 316 nm and 158 nm from single and double pass interferometers respectively. These signals can be interpolated to provide ultra-high resolution positional feedback.

Features and benefits

• 4096x interpolation
• Analogue input bandwidth of <6.5 MHz
• 36-bit parallel format output
• Up to seven axis capability on one bus
• Switch selectable output resolutions
• Addressable registers providing:
• • Position data
  • Card status, inlcluding Liassajous co-ordinates, laser signal strength and system status
• Compact 110 mm x 72 mm board size
• Optional dual axis VME host board to enable to the RPI20 to be used in VME system architectures
