Keithley 615 Electrometer Printer Board Recreation

This repo contains modern reproductions of the buffer/printer PCBs (PC209, PC218) for the Keithley 615 electrometer.

Boards

  • PC218
    • Signal inverter/buffer board
    • Recreation of the origional PC218 schematic using modern SMD components is in the PC218 directory
    • A simplified version using more modern ICs can be found in the PC218v2 directory
  • PC209
    • Signal inverter/buffer and trigger board
    • Simplified version of the origional board can be found in the PC209 directory
      • Same inverter/buffer scheme as PC218v2, with the origional trigger pulse generator and logic reduced down to discrete transistors, to simplify design.
  • Digital Interface Board
    • This will be a new board designed to connect to the 615 via the 50-pin Centronics connector
    • Planned features:
      • Passive data collection
      • Active triggering
      • USB-serial
      • RS-232 via DE-9
      • Ethernet
