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, terminated or unterminated, latching switches
(see Table 3-2 for available switch modules). As with the EX71HD, it can be delivered
preconfigured with any combination of switches with the capability of populating empty slots on-
site as required. The EX72SF is a self-contained unit that uses the EX7000 and an 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.
EX72CC: LXI Based Custom RF Interface Platform
The EX72CC is a 2U(3.5”) enclosure that can house up to six SPDT switches as well as up to six
full size(2.25” square) multi-pole, terminated or unterminated 12V switches. Contact the VTI sales
team for the full list of possible switch choices. As with the EX71HD and the EX72SF, it can be
delivered preconfigured. The EX72CC is a self-contained unit that uses the EX7000 and an AC
power supply built into the assembly. Also provided on the EX72CC is a 32-channel, general
purpose I/O bus.
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, EX72CC, or the EX7400, are delivered with
a complete device configuration file (DCF) 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 DCF also contains all of the point-to-point signal path information.
The information included in the DCF 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.
All EX7000s consists of an LXI Class A compliant digital controller interface, one or more
72-channel relay driver boards, an integrated ac power supply, and a selectable assortment of
electromechanical microwave switches. More than one relay driver board is used in custom
applications where the internal number of coils exceed the 72 coil capacity of a single relay driver
board. As many as four total relay driver boards can be used in large designs. Extremely large
designs, that require five to eight relay driver boards, can be accommodated with special hardware
and software updates. Please consult the factory for details.
