The following commands let you specify thresholds and top-base definitions for individual waveforms:

• :CGMemory Threshold Commands
• :CHANnel Threshold Commands
• :CMODe Threshold Commands
• :DIFF Threshold Commands
• :FUNCtion Threshold Commands
• :NETWorks:TRACe Threshold Commands
• :WMEMory Threshold Commands

Waveform threshold levels can be set to standard percentages or to custom user definitions based on absolute amplitudes.

Threshold levels definitions affect the measurements listed in the following table.
