## Command Syntax

    :WMEMoryN:THReshold:RFALl:LOWer amplitude

<amplitude> is a double.

Where N identifies one of eight {1:8} possible waveform memories. For example, `:WMEMory4`.

## Query Syntax

    :WMEMoryN:THReshold:RFALl:LOWer?

## Description

Sets the Rise/Fall 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 `:WMEMory:THReshold:RFALl:PLOWer` command.

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

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