Using Eye Doctor II with SDAII and SDAIII-Com-
pleteLinQ
Besides being a very powerful yet easy to use analysis tool for fixture de-embedding and equalizer emu-
lation, Eye Doctor II also has several output waveforms that can be processed by other applications for
additional measurements:
Note: The names below appear when using the path Analysis > Eye Doctor II to access the Eye Doctor
functions. When accessing Eye Doctor II via the SDAIII-CompleteLinQ dialog, most of these selections
appear without the "EDr" prefix. (e.g., Emp is equivalent to EDrEmp.)
l
EDrInP - The positive, signal-ended input signal specified by Input1 in Eye Doctor II's Signal Input.
l
EDrInN - The negative, signal-ended input signal specified by Input2 in Eye Doctor II's Signal Input.
l
EDrIn - Either the signal-ended input signal specified by Input1 in 1 Input Mode or the differential
subtraction of Input1-Input2 in Input1-Input2 mode.
l
EDrEmpP - The positive, signal-ended signal output by the Emphasis block.
l
EDrEmpN - The negative, signal-ended signal output by the Emphasis block.
l
EDrEmp - The differential signal output by the Emphasis block.
l
EDrChP - The positive, signal-ended signal output by the Emulate / De-embed block.
l
EDrChN - The negative, signal-ended signal output by the Emulate / De-embed block.
l
EDrCh - The differential signal output by the Emulate / De-embed block.
l
EDrCTLE - The differential signal output from the CTLE block in the Equalizer.
l
EDrFFE - The differential signal output from the FFE block in the Equalizer.
l
EDrOut - The differential signal output from the Equalizer block. This includes all processing per-
formed by Eye Doctor II.
l
EDrClock - The recovered clock signal created by the Clock Recovery block in the Equalizer.
l
EDrResp - The last S-Parameter file viewed using the View Response feature of the Emulate / De-
embed block.
Note: All the above are available as inputs to any oscilloscope Math function or Measurement. However,
only EDrOut and EDrClock are available as inputs to SDAII.
