## Command Syntax

    :WMEMoryN:THReshold:RFALl:METHod  {P1090 | P2080 | PERCent | ABSolute}

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

## Query Syntax

    :WMEMoryN:THReshold:RFALl:METHod?

## Description

Selects the upper and lower waveform threshold definitions using the following arguments:

P1090
  Specifies threshold levels as 10% and 90% values between top and base.
P2080
  Specifies threshold levels as 20% and 80% values between top and base.
PERCent
  Specifies thresholds as custom percentages between top and base. To specify the percent values for the upper, middle, and lower thresholds, use the `:WMEMory:THReshold:RFALl:PUPPer` and `:WMEMory:THReshold:RFALl:PLOWer` commands.
ABSolute
  Specifies thresholds as absolute upper, middle, and lower vertical values. To specify the values, use the `:WMEMory:THReshold:RFALl:UPPer` and `:WMEMory:THReshold:RFALl:LOWer` commands.
  Selects custom user-defined threshold definitions based on absolute unit amplitudes.
