Combining Parameters for Signal Generation Using the Agilent 81133A/81134A Pulse Generator
Agilent 81133A/81134A Pulse Generator User’s Guide, January 2005 69
– Data in either RZ, R1 or NRZ format
– Pseudo random bit stream (PRBS) polynomials
For details on these signals, see “Pattern Modes” on page 70.
•Burst Mode
This mode enables you to generate a burst consisting of data
repeated n times followed by continuous zero data.
In Burst mode, exactly one burst of data is output after either:
– Applying a external signal at the start input.
– Asserting a manual trigger on one of the remote interfaces.
– Pressing the start button on the user interface.
A burst consists of data packets repeated a selectable number of
times (in data pattern mode).
• Repetitive Burst Mode
This mode enables you to generate a repetitive burst consisting of
data repeated n times. A pause of zeros is inserted between two
successive bursts.
The repetitive burst is specified by two numbers. The first number
(n) defines how often the specified data is repeated. The second
number (p) defines the length of the pause that follows the repeated
data.
The length of the pause is calculated by:
p x Length of Data Packets
n
