:CHANnel:THReshold:RFALl:UPPer

:CHANnel Threshold Commands

Command Syntax

:CHANnelN:THReshold:RFALl:UPPer  <amplitude>

<amplitude> is a double.

Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is CHANnel4_2.

Query Syntax

:CHANnelN:THReshold:RFALl:UPPer?

Description

Sets or queries the Rise/Fall threshold's 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 :CHANnel:THReshold:RFALl:PUPPer command.

Use the :CHANnel:THReshold:RFALl:METHod command to set waveform threshold levels to standard percentages or custom definitions.

Use the :CHANnel:THReshold:RFALl:LOWer command to enter a lower threshold level.
