The Agilent Technologies 81200
data generator/analyzer platform
The Agilent 81200 is a modular plat-
form consisting of front-ends, mod-
ules, mainframes and user interfaces,
which can be tailored to your specific
test needs. This guide aims to help
you choose the right components. In
this context, two different fundamen-
tal possibilities in configuring the sys-
tem must be considered. These depend
on how you want to integrate the
Agilent 81200 into your test environ-
ment:
a) Using the 81200 as a "proprietary
system" means that the 81200 will not
be combined with other VXI modules
in a standard VXI system. It can how-
ever, be controlled by a LAN or a
GPIB interface. If a "proprietary sys-
tem" is desired, follow steps 1-3, 4a
and 5 to configure your system (fig-
ure 1).
b) If Agilent 81200 modules are com-
bined with other VXI modules then
an "open VXI system" (the standard
VXI system), is achieved. For this
configuration, please follow steps 1-3,
4b and 5 (figure 1).
For information on upgrading an
existing Agilent 81200, please refer to
page 8.
On each page you'll find tables where
you can enter your choice as a
reminder for ordering.
STEP 1: Selecting the number
of channels required
Figure 2 shows that three different
generator front-ends and four differ-
ent analyzer front-ends are available.
To select the correct front-end, the
following should be checked:
• speed
• data format
• levels
• memory depth
Please note that some of the lower
speed front-ends have two outputs or
two inputs and support a maximum
memory depth of 512 Kbit per chan-
nel, not 1024 Kbit. SMA cables are
not included.
For more details, consult the Agilent
81200 Data Generator/Analyzer
Platform, data sheet, p/n 5965-3415E.
STEP 2: Choosing the modules
The generator and analyzer front-
ends can be fitted together as follows:
• Generator front-ends can be fitted
(any mix) in the Agilent E4831A
Clock and Data Generator Module
or the Agilent E4841A Data
Generator/Analyzer Module.
• Analyzer front-ends only fit into
the Agilent E4841A module. Any
mix of analyzer and generator
front-ends is acceptable, provided
that the same sequence is needed
for the generator and analyzer.
• At least one clock module is essen-
tial; either an Agilent E4805A
Central Clock Module or the
Agilent E4831 Clock & Data
Generator Module. These modules
can drive up to eleven or six
Agilent E4841A modules respec-
tively.
• The sequence of segments and the
segment types (pattern, pause,
PRBS/PRWS) is the same for all
the channels within one module.
For example, if you need to set up
PRBS and control channels, make
sure you run PRBS from one mod-
ule and the control signals from
another module.

in a open VXI environment.
There is a choice of two mainframes.
Both include software, PC, hard disk and floppy drive.
The larger frame can be augmented with one or two expander frames.
