:CHANnel:UDEFined:DISTal
Command Syntax
:CHANnel{1:8}{A|B|C|D}:UDEFined:DISTal <amplitude>
<amplitude> is a double.
Where the required specifier {1:8}{A|B|C|D} identifies a channel by its module slot number and channel letter. For example, channel 3C (CHANnel3C).
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
:CHANnel{1:8}{A|B|C|D}:UDEFined:DISTal?
Description
Sets or queries the upper 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:DISTal 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:MESial command to enter a middle threshold level. Use the :CHANnel{N}:UDEFined:PROXimal command to enter a lower threshold level.
