Use this section of the Pin View pane to specify comparator options.

  • Comparator Symbol — The box to the left of the comparator symbol, as shown in the following figure, indicates the comparator results.
    • H — Indicates a value above VOH.
    • L — Indicates a value below VOL.
    • M — Indicates a value that is below VOH and above VOL.
    • V — Indicates a value that is above VOH and below VOL, which can occur when you set VOL higher than VOH.
    • - — Indicates that the pin is disconnected or cannot be read.
  • VOH — Specifies the DUT output voltage above which the comparator on the instrument pin interprets a logic high (H).
  • VOL — Specifies the DUT output voltage below which the comparator on the instrument pin interprets a logic low (L).
