This dialog is available with Extended Time Domain Analysis option R&S ZNB/ZNBT-
K20 only.
Simulated Bit Pattern / Simulated Rise Time
see Chapter 6.15.2.5, "Eye Diagram Dialog", on page 640
Modulation
see "Modulation" on page 642
High Level / Low Level
see "High Level / Low Level" on page 642.
Encoder
Enables or disables 8b/10b encoding of the original bit stream.
Remote command:
CALCulate<Chn>:EYE:STIMulus:ENCoder
Scrambler
Enables/disables scrambling of the (encoded) bit stream.
The scrambler is a linear feedback shift register (LFSR) implementing the polynomial
G(X) = X^16+X^5+X^4+X^3+1.
Remote command:
CALCulate<Chn>:EYE:STIMulus:SCRambler
Emphasis
The "Emphasis" dialog allows you to introduce a pre-emphasis filter to the digital signal
simulated for the eye diagram measurement. This, together with Equalization, may be
used to compensate for the signal integrity degradations caused by the DUT.
Access: "Emphasis" button in the Advanced Settings Dialog
