Signal Modes
In Data and PRBS pattern modes, the pulse output format can be
selected from RZ, R1, and NRZ. The timing of the different format
is shown in the following diagram:
•RZ
Return to 0 pulse format.
On every 0 bit of the pattern, the signal remains low. On every
1 bit of the pattern, the signal goes to high and then back to
low after the time specified by the pulse width or duty cycle
parameter.
•R1
Return to 1 pulse format.
On every 1 bit of the pattern, the signal remains high. On every
0 bit of the pattern, the signal goes to low and then back to
high after the time specified by the pulse width or duty cycle
parameter.
•NRZ
Non- return to zero pulse format.
A leading edge is generated for a 0 - > 1 data transition, a
trailing edge is generated for a 1 - > 0 data transition.
