:MEASure:PJITter:DDIRac:EDGE?

Query Syntax

:MEASure:PJITterN:DDIRac:EDGE?

Where N identifies one of four possible PAM jitter analyses {1:4}. For example, PJITter4.

Description

For the selected row in the Dual-Dirac PAM Jitter measurements table (see :MEASure:PJITter:DDIRac:SELect), this query returns the edge number defined in the pattern. This edge number is the same as displayed in the first column of the table.

The first row of the table contains the averaged measurements, so this query returns "-1" for the first row.

This query returns "-1" for the first row of the table because that row contains the averaged measurements.

With the PCIe Dual-Dirac 52-symbol pattern, the jitter measurements table has rows for each edge defined in the pattern. Note that some symbols in the pattern do not have edge transitions, so there is no row in the table for that symbol (and a skipped edge number).

You can use the :MEASure:PJITter:DDIRac:TRANsition? query to get the "Level to Level" transition associated with the selected table row.
