Caution
Note
Note
To protect circuits from static discharge, observe anti-static techniques whenever handling
the Agilent E1438 VXI ADC Module.
1. Set up your VXI mainframe. See the installation guide for your mainframe.
2. Select a slot in the VXI mainframe for the E1438 module.
The Agilent E1438D module’s local bus receives ECL-level data from the
module immediately to its left and outputs ECL-level data to the module
immediately to its right. E very module us ing t he local bus is keyed to prevent
two modules from fitting next to each other unless they are compatible. If you
will be using the local bus, select adjacent slots immediately to the left of the
data-receiving module. If the VXI bus is used, maximum data rates will be
reduced but the module can be placed in any available slot.
3. Using a small screwdriver or similar tool, set the logical address configura-
tion switch on the E1438. (See the illust ration on the next page.) Each module
in the system must have a unique logical address. The factory default setting
is 1100 0000 (192).
For optimal phase noise performance in multi-module systems it is recommended that the first
channel be an Agil ent E1438C or D. The Agilent E1438C does n ot suppo rt loca l b us or f i ber opti c
transfers.
Multi-module systems may include multiple Agilent E1438s or Agilent E1439s but not a mixture
of the two types of module s.

Tocleanfiberopticconnectors
To clean fiber optic connectors
The Agilent E1438D has a fiber opti c serial FPDP (front panel data port ). Since the data transmit s
via light, the f iber optic connec tions must be clean. The following procedure describes how to
clean fib er optic connectors.
Caution
Caution
Note
Do not use any type of foam swab to clean optical fiber ends. Foam swabs can leave filmy
deposits on fiber ends.
1. Apply pure isopropyl alcohol to a clean lint-free cotton swab or lens paper.
Cotton swabs can be used as long as no cotton fibers rema in on the fiber end after clea ning.
2. Clean the connector while avoiding the ends of the fiber.
3. Apply isopropyl alcohol to a new clean lint-free cotton swab or lens paper.
4. Clean the fiber end with the swab or lens paper.
Do not scrub during this initial cleani ng because grit can be caught in the swab and become a
gouging element.
5. Immediately dry the fiber end with a clean, dry, lint-free cotton swab or lens paper.
6. Blow across th e co nne ctor end face from a distance of 6 to 8 inches using filtered, dry ,
compr essed air. Aim the compressed air a t a shallow a ngle to the fiber end face.
Nitrogen gas or compressed dust remover can also be used.
Do not shake, tip, or invert compressed air canisters because this releases particles in the
can into the air. Refer to instructions provided on the compressed air canister.
7. As soon as the connector is dry, connect or cover it for later use.
To order multimode LC fiber optic cables, call Stratos Lightwave at (708) 867-9600
(http://www.stratoslightwave.com) or call Fiber Instrument at (800) 500-0347

Store th e mo d ul e in a cl ean, dry, and static fre e envi ro nment.
For other requirements, see storage and transport restriction in “Technical Specif ications”.
To transport the module
Caution
•Package the module using the original factory packaging or packaging identical to the factory packaging.
•If returning the module to Agilent Technologies for service, attach a tag
describing the following:
•Type of service required
•Return address
•Model number
•Full serial number
In any corresponde nce , refer to the module by model number and full serial number.
•Mark the container FRAGIL E to ensure careful handling.
•If necessary to package the module in a conta iner other than origina l pac kaging, observe the
following (use of other packaging is not recommended):
•Wrap the module in heavy paper or anti-static plastic.
•Protect the front panel with cardboard.
•Use a double-wall carton made of at least 200-pound test (32 ECT) material.
•Cushion the modul e to prevent damage. For example , se ve ral la ye rs of pla stic b ubbl e wrap
is usually suffici ent.
Do not use styrene pellets in any shape as packing material for the module. The pellets do
not adequately cushion the module and do not prevent the module from shifting in the
carton. In addition, the pellets create static electricity that can damage electronic
components.

TousetheResource Manager
To use the Resource Manager
The Resource Manager is a program from your hardware interface manufacturer. It looks at the
VXI mainframe to determi ne what module s are in stalle d. You need to run it eve ry ti me you po wer
up. If you get the message: "VIS UCCESS_DEVICE_NPRESENT" then run the Re source
Manager.
Before running the Agilent E1438 software make sure that your hardware is configured correctly
and that the Resource Manager runs successfull y. Before using your measurement system, you
must set up all of its devices, including setting their addresses and local bus locations. No two
devices can have the same address. Usually addres s es 0 and 1 are taken by the Re source Manager
and are not available.
For more information about the Resource Manager, see the documentation with your hardware
interface.
Note
Most Resource Managers will recognize the manufacturer and model number of the
Agilent E1438 but if your interface require s that you enter this information manually, use the
following:
Manufacturer number: 4095 (Hex FFF)
Model number: 622 (Hex 26E)

TousetheVXIplug&play Soft Front Panel (SPF)
To use the VXIplug&play Soft Front Panel (SPF)
In a Windo ws environm ent, the Soft Front Panel is the best place to sta rt to explore the
capabilit ies of the Agilent E1438. The Soft Front Panel is useful for checking your system to
make sure that it is ins talled correctly and that all of its parts are worki ng. You can also use it to
make actual mea surements, since it acc es ses most of the Agilent E1438’s functionality.
Select the shortcut in your program group to start the program. This
assumes you have already installed al l required hardware and drivers (including VISA) and have
run the configurator and Resource Manager required by your hardware interface.
If prompted for the resour ce des criptor, use the default "VXI::192" unless the logical addre ss of
the Agilent E1438 has been cha nged from its default sett ing of 192. If it has been changed, type
the appropriate logical address inst ead of 192, then press OK.
Note
You can also run the Agilent E1438 Front Panel in a simulation mode without an Agilent E1438
module, a hardware interface, or VISA libraries by typing "sim" in place of the resource
descriptor.
The Agilent E1438 Front Panel Help, available from the Soft Front Pa nel Help menu, describes
the capability of the Soft Front Panel and has links to functions tha t control and define many of
the parameters.
