:MEASure:THReshold:RFALl:LOWer

Threshold Definition Commands

Command Syntax

:MEASure:THReshold:RFALl:LOWer  <amplitude>

<amplitude> is a double.

Query Syntax

:MEASure:THReshold:RFALl: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 Rise/Fall threshold's global 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 :MEASure:THReshold:RFALl:PLOWer command.

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

Use the :MEASure:THReshold:RFALl:UPPer command to enter a upper threshold level.

:MEASure:THReshold:RFALl:METHod ABSolute
:MEASure:THReshold:RFALl:UPPer 125E-3
:MEASure:THReshold:RFALl:LOWer -125E-3
