Description

Sets the lower threshold definition level. This value is used when making measurements with custom threshold definitions that are based on absolute amplitude. When custom threshold definitions are based on percent, use the :MEASure:THReshold:PROXimal command.

Use the :MEASure:THReshold:METHod command to specify the use of custom threshold definitions. Use the :MEASure:THReshold:UNITs command to select levels base on absolute amplitude values.

Use the :WMEMory{1:8}:UDEFined:DISTal command to enter a upper threshold level. Use the :WMEMory{1:8}:UDEFined:MESial command to enter a middle threshold level.
