:DIFF:UDEFined:MESial
Command Syntax
:DIFF{1:8}{A|C}:UDEFined:MESial <amplitude>
<amplitude> is a double.
Where the required specifier {1:8}{A|C} identifies the differential channel by its module slot and channel letter. For example, the differential waveform of channels 1A and 1B would be identified as :DIFF1A.
The channel specifier will fail if it does not include a slot number. If instead the suffix's channel letter is missing, the command defaults to letter A. As a result, the best practice is to always explicitly specify the channel by including both the module slot number and channel letter.
Query Syntax
:DIFF{1:8}{A|C}: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:UDEFined:DISTal command to enter a upper threshold level. Use the :DIFF:UDEFined:PROXimal command to enter a lower threshold level.
