Getting Started with the Agilent 81133A and 81134A
Now that you have unpacked the instrument and plugged it in,
let´s take a look at the main elements of the front panel.
Softkeys
Numeric Keys
Global inputs
and outputs
Channel-specific
inputs and outputs
Navigation knob
Tab Keys to navigate
between the pages
Switch on the instrument. You can immediately start playing with the settings.
Start by pressing the tab keys. You see that only the lower part of the panel page
changes. You can switch between five panel pages, which allow you to set
parameters for different instrument settings.
The parameters at the upper part of the panel page are valid for the whole instrument.
Navigate through the pages with the Tab Keys

Changing Parameters
The navigation knob makes it easy to move through
and set the parameters.
Rotate the navigation knob
to move from one parameter
to the next.
Let’s select a parameter
from a selection list.
Press the navigation knob
to open the selection list
(like clicking
with the mouse).
Rotate the navigation knob
to scroll through the list.
Select an item by pressing
the navigation knob.
You have three options for using the navigation knob.

Changing Parameters
Now let´s change a number field
Press the navigation knob
once to focus at the
number field.
Turn the navigation knob
to set the number
When you rotate the navigation knob
the value changes. You can do this in run time.
It let’s you immediately see the changes on a scope.
Or, to change one digit
Press the navigation knob
once when you are done.
Press and rotate the
navigation knob to
select the digit.
You can also press the
arrows next to the navigation knob.
Release the navigation knob.
Now when you rotate it,
the number changes.
Press the navigation knob
once when you are done.
You can also:
Use the arrows next the
navigation knob
Enter a value
with the key pad.
to select a digit.

Setting Up a Data Pattern
Imagine, you have designed a new digital circuit with ECL logic and
3.3 GHz clock, and you want to check its correct behavior.
To test it, you decide to simulate a 32-bit pattern signal with NRZ
data output format:
11110011100110010010100100000000
Protect the DUT
Whenever you change a parameter, the generated signal immediately changes.
To protect your DUT, make sure you disconnect the channel outputs first.
Do this by pressing the softkey next the following function:
The open contactor shows you
that your DUT is now disconnected
Now let’s set the instrument parameters
These define the signal that will be generated.

First, disconnect the outputs
to protect the DUT
2
Choose the Pulse/Pattern Mode
for the Signal

Setting Up a Data Pattern
You can now set the channel mode, timing and
level parameters for the channel
4
Indicates that the Parameters
are set for Channel 1
The LEDs show the status
of the outputs
gray = disabled, green = enabled,
crossed out = all outputs disconnected
Select the ECL level format

You can switch
between the two channels
by pressing this softkey
Select Pulse Mode Data

Setting Up a Data Pattern
Reconnect the DUT
When you are done, you can reconnect the DUT by clicking the following softkey:
If you attach a scope (as DUT), you can immediately see the signal
You can use the generator’s trigger output to trigger the scope.
The LEDs tell you which
outputs are enabled
2
Enable the Trigger Output ...

Switch to Aux Page
Now you can view the data pattern and the trigger output signal
on your oscilloscope

What Else You Can Do
The Agilent 81133A and 81134A Pulse/Pattern Generators are high-end,
easy-to-use tools for generating pulses, patterns and data at speeds
up to 3.35 MHz. They are ideal instruments for testing logic devices
(for example, ECL, LVPECL, LVDS) and other digital devices with
clock rates from 15 MHz to 3.35 GHz.
You can use the Pulse/Pattern Generators for applications where timing and
performance are critical and full control over signal jitter is required.
The instruments are ideal data and pattern sources for eye diagram
measurements.
Your advantages are
Fast rise times, low jitter
and full parameter flexibility
PRBS from 25-1 to 231-1
When timing is critical, the 81133/34A’s
fast rise times, the low jitter and full parameter
flexibility make it an ideal pulse,
You can evaluate the performance of a device
in eye diagram measurements with PRBS
from 25-1 to 231-1.
clock and data source.
Full signal manipulation
You can add jitter to clock or data signals
with the Delay Control Input and deform the
eye with the Variable Crossover Point.
Predefined Levels
You can use the predefined levels
to easily set up channels for commonly
used logic families. These are:
ECL, LVPECL, LVDS.
Data can be 8 kB of pattern memory
You can create large data patterns
with 8 kB of pattern memory.

Requirements and Possibilities for Remote Control
Using the Pulse Generator's Remote Control Interfaces
You can integrate the Pulse Generator in your production environment.
Its remote programming interfaces (USB, LAN, GPIB) allow you to set up
extensive tests that involve several instruments.
The accompanying Agilent I/O Libraries for instrument control must be
installed on the controlling PC.
It is possible that your Generator’s firmware is not set up for USB.
USB functionality will be included in a later release of the firmware.
Check the Agilent Web page for update information.
For detailed information on how to connect the instrument
physically to your external PC, and what you have to do to talk
to the instrument, please refer to the Programming Guide
delivered on the Product CD.
