:NETWorks:TRACe:THReshold:RFALl:UPPer
Command Syntax
:NETWorks:TRACeN:THReshold:RFALl:UPPer <amplitude>
<amplitude> is a double.
Where N identifies a specific trace and must be selected from 1 to 128 {1:128}.
Query Syntax
:NETWorks:TRACe{1:128}:THReshold:RFALl:UPPer?
Description
For the indicated S-parameter trace, sets or queries the Rise/Fall threshold's custom upper-threshold definition level. This command is used when making measurements with custom threshold definitions that are based on absolute amplitude. Before using this command,
- Use the
:NETWorks:TRACe:THReshold:RFALl:METHodcommand to specify the use of custom threshold definitions. - When custom threshold definitions are based on percent, use the
:NETWorks:TRACe:THReshold:RFALl:PUPPercommand instead.
Use the :NETWorks:TRACe:THReshold:RFALl:LOWer command to enter a lower threshold level.
The custom upper-threshold setting can be set from the front panel by choosing Measure > Thresholds... and in the Thresholds tab, Rise/Fall subtab of the Configure Measurements dialog box, setting the signal's Top-Base Definition.
Depending on the waveform type, specify the level in the units shown in the following table.
