## Command Syntax

    :MEASure:JITTerN:JITTer:TFILter:DFACtor <damping_factor>

Where N identifies one of four possible jitter/noise analyses {1:4}. For example, `JITTer4`.

<damping_factor> is a double.

## Query Syntax

    :MEASure:JITTerN:JITTer:TFILter:DFACtor?

## Description

When the Second Order TIE filter edge shape is selected (see `:MEASure:JITTer:JITTer:TFILter:SHAPe`), this command lets you specify the filter's Damping Factor:

< 1 | underdamped
> 1 | overdamped
= 1.0 | critically damped
= 0.707 | Often considered ideal or optimal because of its fast settling time (optimally flat) and Butterworth type response.
