Technical data

This query returns the "instantaneous" number of data rate ratio (Actual DRR),
calculated from the counts obtained in the last deci-second. This value is available
even when the accumulation is turned off.
PLUGin Subsystem
PLUGin Subsystem - Reference
The PLUGin subsystem controls the optional Interference Channel #J20, a
hardware plug-in module.
The Interference Channel #J20 can be used to add sinusoidal interference to the
generated data and to simulate intersymbol interference.
Sinusoidal interference adds a common-mode, differential, or single-ended
sinewave signal to the generated data. It is used to test common mode rejection
of a receiver and to emulate vertical eye closure.
Intersymbol interference of various degree is generated by selecting one of nine
on-board traces.
