Description

For an IEEE 12-Edge Output Jitter measurement, selects the waveform's edge (edge category) on which a returned measurement result is based. The actual measurement result is returned using the :MEASure:JITTer:OJITter:JNU? query. The measurement result is always for a specified type and edge category. To select the output jitter type, use the :MEASure:JITTer:OJITter:SJNU 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 Arguments for Selected Waveform Edges

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

Command Coupling

Changing the setting for this measurement also changes the setting for the IEEE EOJ and Jrms measurements.

• :MEASure:JITTer:OJITter:EOJ:ECATegory
• :MEASure:JITTer:OJITter:JRMS:ECATegory

This setting does not affect the edge-category selection that is used to construct the displayed Output Jitter Histogram. The histogram's edge-category setting is made using the following command:

• :DISPlay:JITTer:OJITter:ECATegory

Use the :MEASure:JITTer:OJITter:STATe command to turn on IEEE jitter measurements.
