IGURE 1-2: EX72SF (SHOWN WITH A FULL COMPLIMENT OF AGILENT SWITCHES)
The EX72SF is a 2U (3.5”) enclosure that can house up to six Agilent SPDT switches as well as
up to six full-size Agilent multi-pole single throw latching terminated or unterminated switches. It
can be delivered preconfigured from the factory with twelve switches or can be purchased with
less than the full compliment of switches. Additional switches can be added by the customer at
later dates. The EX72SF is totally self contained unit with EX7000-OEM board set and ac power
supply built into the assembly. Also provided on the EX72SF is a 32-channel, general purpose I/O
bus. Access to this bus is through a front panel-mounted 37-pin D-sub connector. Further details
on this bus can be found in
Section 3.
See
Section 3, Basic Operation, for a complete list of Agilent switch modules that can be used
with the EX72SF.
EX7400: LXI Based Custom RF Interface Platform
The EX7400 is built around the same internal components as the EX71HD and EX72SF. It starts
life as a 4U high and 24” deep rack mountable enclosure. It can be purchased in this configuration
allowing a customer to add their own RF and microwave components to the front and rear panels
as well as the removable mezzanine that is located at approximately the mid way point between
the top and bottom covers. It may also be supplied as a custom or special unit which is
preconfigured at the factory with all of the components and inter-connect cabling specified by the
customer.
COMMON FEATURES
Preconfigured units, whether an EX71HD, EX72SF, or the EX7400, are delivered with a complete
Configuration File that contains all the pertinent details about each programmable device mounted
inside. In the case of the EX7400, which may contain internal inter-connect path cabling, the
Configuration File also contains all of the point-to-point signal path information. The information
included in the Configuration File allows the user to establish a complete signal route by
indicating only the end points in a compliant IVI-Switch Connect statement, thus simplifying the
programming task.
The EX7000 series assemblies, referred to here after as EX7000, consists of an LXI Class A
compliant digital controller interface, one or more 72-channel relay driver board, integral ac power
supply, and a selectable assortment of electromechanical microwave switches. More than one
relay driver boards are used in custom applications where the internal number of coils exceeds the
72 coil capacity of one relay driver board. As many as four relay driver boards, one plus three
