NRZ PseudoĆRandom (PRBS) Signal
The NRZ Pseudo-Random Signal stored in waveform file PRBS15.PAT
(Figure D–17) is a 32 Kbit (15 step) M-series pseudo-random signal generated
with the shift register shown in Figure D–18. All 1s are set in the initial register
and the data is changed every two samples.
H Waveform points: 32,767
H Clock frequency: 100 MHz
H Output parameters: Filter Through

The NRZ Pseudo-Random Signal stored in sequence file PRBS15.SQC
(Figure D–19) is produced by repeating the PRBS15.PAT file eight times. To
display the sequence, use the command (page 3–70).
