Combining Parameters for Signal Generation Using the Agilent 81133A/81134A Pulse Generator
Agilent 81133A/81134A Pulse Generator User’s Guide, January 2005 71
Signal ModesIn Data and PRBS pattern modes, the pulse output format can be
selected from RZ, R1, and NRZ. The timing of the dif ferent format is
shown in the following diagram:
•RZ
Return to 0 pulse format.
On every 0 bit of the patter n, 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 o f the pattern, t he signal remain s high. On every 0 bi t
of the patter n, the signal goes to low and then back t o 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 tr ansition, a trailing
edge is generated for a 1 -> 0 data transition.
