:CGMemory:THReshold:GENeral:LOWer

:CGMemory Threshold Commands

Command Syntax

:CGMemoryN:THReshold:GENeral:LOWer <amplitude>

<amplitude> is a double.

Where N identifies one of eight color grade memories. For example, the color grade memory 2 would be identified as :CGMemory2.

Query Syntax

:CGMemoryN:THReshold:GENeral:LOWer?

Description

MEASUREMENTS AFFECTED

Infiniium uses the waveform's lower, middle, and upper threshold levels during these measurements:

  • duty-cycle distortion
  • rise time
  • fall time

Sets or queries the General threshold's lower 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 :CGMemory:THReshold:GENeral:PLOWer command.

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

Use the :CGMemory:THReshold:GENeral:UPPer command to enter a upper threshold level. Use the :CGMemory:THReshold:GENeral:MIDDle command to enter a middle threshold level.
