1. Define Analysis Name - Save analysis for future use; Recall prior saved analysis. Note: Save/Recall are under development and not available at this time.

Name Description Entry Value(s) Status Type Limits Comment
PreCursors Pre-cursor values Real array Values in dB units. Comma separated list.
PostCursors Post-cursor values Real array Values in dB units. Comma separated list.
CursorNorm Cursor normalization option Integer [0,3]

0 = gain at 0 Hz

1 = sum absolute (tap values)

2 = main tap value

3 = gain at Nyquist frequency

NormLevel Normalization level Real > 0 Scalar level
Poles LPF pole values Real array > 0 Values in Hz. Comma separated list.

2. Setup Analysis

Name Description Entry Value(s) Status Type Limits Comment
AnalysisName Analysis name String Alpha-numeric characters or underbar - case sensitive - start with alpha character.
BitRate Bit rate Real > 0 Bits per second
SamplesPerBit Samples per bit Integer >= 4
DataType Data pattern type Integer [0,1]

0 = Pseudo-random sequence (PRBS)

1 = Sequence of N 1's and N 0's (N_1_N_0)

PRBS_Length PRBS register length Integer [4,8] Used when Data pattern type = PRBS
N_Value N value Integer [2,32] Used when Data pattern type = N_1_N_0
