Signal Input button - Touch to open the Signal dialog, which is used to configure settings for the active
lane including the data source(s), crossing level and signal type, and to enable the display of signal that
"flows" to the Emphasis block of the SDA flowchart.

Emphasis button - Touch to open the Emphasis dialog, which is used to configure pre-emphasis/de-
emphasis settings for the signal that flows from the Signal Input(s) block. This button is enabled when

De-embed/Emulate button - Touch to open the De-embed/Emulate dialog, which is used either to con-
figure fixture and channel de-embedding/emulation, or to enable the VirtualProbe option for the active
lane. This button is enabled when the EyeDoctor II option is present on the oscilloscope. For more infor-
mation, see

Emulate / De-embed Overview

.

Linear EQ button - Touch to open the Linear EQ dialog, where you can apply CTLE (Continuous Time Lin-
ear Equalization) or FFE (Feed-forward Equalization) to the active lane. This button is enabled when the
EyeDoctorII option is present on the oscilloscope. For more information, see

Clock Recovery Source switch - This unlabeled button is located immediately to the left of the Clock
Recovery button. When using an explicit reference clock, set the Clock Recovery Source switch to the
"Blue" position to enable the Ref Clock Input button. In this position, the clock recovery uses transitions
of the reference clock input. When set to the "Red" position, SDAIII-CompleteLinQ will perform a soft-
ware clock recovery using edges from the signal flowing out of the Linear EQ box. In either position, the
settings configured in the Clock dialog are utilized.

Clock Recovery button - Touch to access the Clock dialog.

Ref Clock Input button - When using an explicit reference clock, set the clock recovery switch to the
"Blue" position to enable the Ref Clock Input button. Then, touch Ref Clock Input to open the dialog for
configuring the source and other attributes of the reference clock.
