Modules 660 MHz data generator/analyzer module – holds four front-ends, any mix Agilent E4841A
660 MHz clock and data generator module – holds two generator front-ends, any mix.
Clocks up to six Agilent E4841A modules. Agilent E4831A
660 MHz central clock module, which clocks up to eleven Agilent E4841A modules Agilent E4805A
and up to two Agilent E4805s.
Required in all systems that include analyzer front-ends, and for all systems with seven Agilent E4805A
or more Agilent E4841As.
8-line trigger input for TTL signals. When branching on external events Agilent E4805A
(hardware signals) other than VXI-ECL trigger lines or compare errors is required. Opt 002
Deskewprobe, includes Agilent 1144A 880 MHz active probe and a BNC (f) to SMA (m) Agilent E4805A
adapter (part number 1250-1200). Opt 003
Which clock module?
The Agilent E4831A Clock & Data
Generator Module can be an eco-
nomic way of building pulse or
data generators as it includes slots
for two front-ends. Please remem-
ber that the Agilent E4831A can
only be used for generator chan-
nels. For applications needing
many channels, analyzer channels
or more than two looping levels,
use the Agilent E4805A Central
Clock Module.
STEP 3: Decision - VXI integration
or not
If you want to combine the Agilent
81200 modules with other VXI
modules to achieve an "open VXI
system," then go to STEP 4b.
If you want to use the Agilent
81200 as a “proprietary system,”
meaning the Agilent 81200 will not be
combined with other VXI modules in
one system, then go to STEP 4a.
STEP 4a: Selecting the mainframe
If you’ve made the decision to config-
ure a "proprietary system," you are
now in the position to select a main-
frame. Two mainframes are available,
the Agilent E4840A small frame with
three free slots and the Agilent
E4849B mainframe with 10 free
slots. Both mainframes include a
built-in PC running Windows NT
4.0®. The user software is also
installed. All modules and front-ends
ordered with the mainframes come
factory installed.
Generator-only systems.
Generator systems or generator/analyzer systems.
more generator front-ends are needed.
