Command Syntax

:DIFFN:UDEFined:MESial <amplitude>

<amplitude> is a double.

Where N identifies the differential waveform, which must be selected from {1:8}{A|C}. For example, the differential waveform of channels 1A and 2A would be identified as :DIFF1A.

Query Syntax

:DIFFN:UDEFined:MESial?

Description

Sets or queries the middle 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:MESal 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 :DIFF{1:4}:UDEFined:DISTal command to enter a upper threshold level. Use the :DIFF{1:4}:UDEFined:PROXimal command to enter a lower threshold level.
