## Description

Turns logic-level tracking on or off, which affects the masks Y-axis scaling and position. Use the `:MTESt:Y` command to adjust logic-level one. Use the `:MTESt:Y` command to adjust logic-level zero.

ON
  Logic level tracking is enabled and the logic levels track each other, allowing you to manually move the mask up and down on the display. For example, if you adjust the logic 1 level by 5 mW, the logic 0 level will also move by 5 mW.
OFF
  You can independently scale the mask to logic level one and zero.
