V1 bugs:

  • crystal oscillator holes are too large
  • C3 should be 330nF

Must-have:

  • mounting holes
  • input voltage protection
  • supply voltage LED indicator
  • reverse supply voltage protection
  • cheaper voltage reference
  • DUT discharge resistor or push-pull output (v1 can "source" current but cannot lower the DUT voltage by itself)

Nice-to-have:

  • RESET button
  • microcontroller - provide fast sampling and buffer data to on-board/on-chip RAM - allow RC characteristics to be plotted
  • transistor-tracer (add another channel)
  • split-supply functionality (provide op-amp circuit "input vs output" plot over a voltage range)
