## Query Syntax

    :MEASure:JITTerN:JITTer:ISI?

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

## Description

Returns ISI-J (p-p), Inter-Symbol Interference, which is the peak-to-peak (p-p) range of the jitter that is correlated to rising edges or the jitter that is correlated to falling edges (whichever is greater). When `RISing` edge or `FALLing` edge is selected for `:MEASure:JITTer:JITTer:EDGE`, only the specified edges are used in the calculation of ISI-J (p-p).
