Using the Agilent 81133A/81134A Pulse Generator Timing of Generated Signals
82 Agilent 81133A/81134A Pulse Generator User’s Guide, January 2005
Repetitive Burst
The following figure shows the typical timing for the repetitive burst.
Characteristics • A burst of repeated data can be either generated continuously or
can be started manually or by the ar ming source.
• You can select the number of repeated data in the range 4 ... 16384
(in increments of 4).
• You can specify the factor p for calculating the len gth of the pause
that follows the repeated data in the range 4... 16384 (in increments
of 4):
null data length = Data pattern length x p
• The instrument mode is RBurst.
• The pattern mode is Data.
• You can select bet ween RZ, NRZ and R1 si gnal mode for each ou tput.
In R1 and RZ mode, the pulse widt h can be selected as either width
or duty cycle.
• You can select between normal and inverted signals for each output.
• For the clock source, you can select from:
–Internal (YIG Oscillator)
–External signal at Clock Input
–External 10 MHz Reference at Clock Input
For more information about the clock sources, see “Clock Sources”
on page 73.
• The Trigger Out marks every star t of the repetitive data pattern, as
long as no frequency divider has been ap plied.
