## Command Syntax

    :MEASure:JITTerN:JITTer:SMEThod {AUTO | SPECtral | TFIT}

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

## Query Syntax

    :MEASure:JITTerN:JITTer:SMEThod?

## Description

This command lets you specify the method used to measure random jitter or random interference:

AUTO
  Automatically chooses between the `SPECtral` and `TFIT` methods based on the perceived amount of BUJ/BUI.
SPECtral
  This method gives accurate results, but incorrectly characterizes BUJ/BUI as RJ/RN. Results are calculated using the aliased spectrum.
TFIT
  (Tail Fit) This method is less accurate than the `SPECtral` method, but it is better at distinguishing BUJ/BUI. Results are calculated using the tails of the histogram.
