Command Syntax

:CHANnelN:UDEFined:PROXimal  <amplitude>

<amplitude> is a double.

Where N identifies a specific channel and must be selected from {1:8}{A|B|C|D}. For example, CHANnel3C.

Query Syntax

:CHANnelN: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 :CHANnel{N}:UDEFined:DISTal command to enter a upper threshold level. Use the :CHANnel{N}:EMEMory:MESial command to enter a middle threshold level.
