Pulse and Data Functionality
The 8133A ’s standard configuration
includes one pulse channel. A second
channel can be added. This can be
either:
· pulse/data channel (option 002)
· pulse channel (option 003)
Option 002 allows 32 bit, digital
pattern generation in NRZ and RZ
(50%duty cycle) mode.
Pulse/data channel 2 can also be
programmed to provide a pseudo-
random binary
~sequence (PRBS) of
data,a PRBS of 2 23-1 , which
conforms to CCITT 0.151.PRBS
generation capability finds a
particular application,in allowing the
instrument to be used as a data
source for eye diagram
measurements.
Human Interface
You will particularly appreciate the
interactive human interface when you
are operating the Agilent 8133A on
the bench. The easy access to all
parameters helps you concentrate on
the measurement task and react
immediately to unexpected problems.
The constant vernier steps for
parameters allow you to increment or
decrement through the entire
parameter range with a fixed step-
size,using only one key, which is
especially helpful when doing margin
testing.
The immediate error-guidance lets
you know what ’s wrong,with
messages like ”width> Period ”, and
how to fix it,with arrows indicating
that a parameter should be increased
or decreased. You can quickly recall
last valid setting if you prefer.
The Agilent 8133A is available in four different configurations. The differences are timing capabilities and number of channels with different
functionality.
