## Command Syntax

    :NETWorks:TRACeN:THReshold:GENeral:MIDDle  <amplitude>

<amplitude> is a double.

Where N identifies a specific trace and must be selected from 1 to 128 {1:128}.

## Query Syntax

    :NETWorks:TRACe{1:128}:THReshold:GENeral:MIDDle?

## Description

For the indicated S-parameter trace, sets or queries the custom middle-threshold definition level. This command is used when making measurements with custom threshold definitions that are based on absolute amplitude. Before using this command,

- Use the `:NETWorks:TRACe:THReshold:GENeral:METHod` command to specify the use of custom threshold definitions.
- When custom threshold definitions are based on percent, use the `:NETWorks:TRACe:THReshold:GENeral:PMIDdle` command instead.

Use the `:NETWorks:TRACe:THReshold:GENeral:UPPer` command to enter a upper threshold level. Use the `:NETWorks:TRACe:THReshold:GENeral:LOWer` command to enter a lower threshold level.

The custom middle-threshold setting can be set from the front panel by choosing Measure > Thresholds... and selecting the Thresholds tab, General subtab in the Configure Measurements dialog box.

Depending on the waveform type, specify the level in the units shown in the following table.
