## Query Syntax

    :MEASure:JITTerN:JITTer:PJ?

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

## Description

Returns PJ (δ-δ), Periodic Jitter Delta-Delta, which is the width of the bimodal equivalent model used to represent all uncorrelated periodic jitter as defined in the dual-Dirac model for jitter. Deterministic jitter is defined by the dual-Dirac jitter model as all those components of total jitter that do not fit a Gaussian probability density function.
