Combining Parameters for Signal Generation Using the Agilent 81133A/81134A Pulse Generator

Agilent 81133A/81134A Pulse Generator User’s Guide, September 2008 71

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.
