Query Syntax

:MEASure:THReshold:EREFerence?

Description

Sets the reference used to when establishing custom threshold definitions.

TBASe
Selects custom levels based on Vtop (100%) and Vbase (0%). When TBASe is selected, use the :MEASure:TBase:METHod command if you want to define custom the top and base levels.
OZERo
Selects custom levels based on one and zero levels.

This command is available in Eye/Mask mode only.
