Description

Selects the type of waveform edge (edge category) on which to construct the displayed Output Jitter Histogram graph. This histogram is displayed in Jitter mode when 12-Edge Output Jitter measurements on PAM4 waveforms is activated using the :MEASure:JITTer:OJITter:STATe command.

Command arguments select a specific waveform edge for the histogram: rising or falling. Arguments for rising edges start with the letter R. Arguments for falling edges start with the letter F. For example, the argument R23 selects the rising edge from the waveform level 2 to level 3. The default argument ALL selects all edges. You can also select to have a composite of Rising (R03) and Falling (F30) edges using the C03 argument.

The following table shows the position of related measurements (by command argument) on the Output Jitter panel.

Command Argument Versus Selected Edge

Starting Level	Destination Level
	To L0	To L1	To L2	To L3
From L3	F30	F31	F32
From L2	F20	F21		R23
From L1	F10		R12	R13
From L0		R01	R02	R03

This command does not affect the edge-type selections that are used to return specific measurements made with the following commands:
