8133A 3 GHz Pulse Generator
The need for pulse generation isfundamental to any device
characterization task. The ability toemulate the pulse conditions to which
the device will be subjected isessential. This emulation should
include both typical and worst caseconditions. Such accurate emulation
requires superlative signal integrity
and timing performance.

Setting Standards
The Agilent 8133A 3 GHz Pulse
Generator provides pulses with
programmable period from 333 ps to30 ns, full 3 GHz pulse capability on
all channels. The pulse width can be
programmed too, along with a delayor the interchannel delay. At thesefrequency ranges the transition time
performance becomes critical; lessthan 100 ps is specified, less than60 ps is typical, so excellent signal
integrity is assured. And last but notleast, a typical jitter of 1 ps creates
precise and accurate timingconditions.

Pulse and Data Functionality

Human Interface

The 8133A ’s standard configuration
includes one pulse channel. A second
channel can be added. This can beeither:· pulse/data channel (option 002)
· pulse channel (option 003)

You will particularly appreciate theinteractive human interface when you
are operating the Agilent 8133A on
the bench. The easy access to allparameters helps you concentrate on
the measurement task and react
immediately to unexpected problems.
The constant vernier steps forparameters allow you to increment ordecrement through the entire
parameter range with a fixed stepsize,using only one key, which isespecially helpful when doing margin
testing.

Option 002 allows 32 bit, digitalpattern generation in NRZ and RZ(50%duty cycle) mode.
Pulse/data channel 2 can also be
programmed to provide a pseudorandom binary~sequence (PRBS) of
data,a PRBS of 2 23-1 , which
conforms to CCITT 0.151.PRBS
generation capability finds aparticular application,in allowing theinstrument to be used as a data
source for eye diagram
measurements.

The immediate error-guidance lets
you know what ’s wrong,withmessages like ”width> Period ”, andhow to fix it,with arrows indicatingthat 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.
