## Command Syntax

    :DIFFN:THReshold:GENeral:PAM:ASTHresholds

Where N identifies a specific differential waveform in the form "<connection1-8>_<ch1|ch3|ch5|ch7>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1|ch3|ch5|ch7>". When two channels are paired to create a differential waveform and a common-mode waveform, the odd-numbered channel is used when specifying the waveform. For example, connection 5 differential waveform 3 (from the pairing of channels 3 and 4) is `DIFF5_3`.

## Description

When specifying PAM general thresholds and you select the ± Hysteresis threshold definition for the selected signal (see `:DIFF:THReshold:GENeral:METHod`), you can send this command to automatically set the PAM thresholds and hysteresis using a vertical histogram measurement.

The automatically determined PAM thresholds and hysteresis values can be adjusted using the `:DIFF:THReshold:GENeral:PAM:THResholds:EYE` and `:DIFF:THReshold:GENeral:HYSTeresis` commands.
