Command Syntax

:FUNCtion{1:64}:UDEFined:PROXimal <amplitude>

Where the {1:64} specifier identifies one of sixty four math functions that you can create. For example, :FUNCtion2.

Where <amplitude> is an double.

Query Syntax

:FUNCtion1{1:16}:UDEFined:PROXimal?

Description

Sets or queries 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 :FUNCtion{1:16}:UDEFined:DISTal command to enter a upper threshold level. Use the :WMEMory{1:8}:FUNCtion:MESial command to enter a middle threshold level.
