The Model 7002 Switch System is a 10-slot mainframe
that supports up to
400 2-pole multiplexer
channels or 400 matrix crosspoints. The front panel
includes a unique interactive
display of channel
status for quick programming.
Scanning speeds of up to 165 channels per second are possible with
the high density switch cards. The wide selection of more than 30 different
switch cards makes the 7002 one of the most flexible switching
mainframes
available.
Reduce the Size and Cost
of Your Switching Application.
Up to 400 channels of 2-pole switching. A single Model 7002 mainframe
can accommodate up to ten 40-channel cards. That’s 400 channels in a
single full-rack package that is only 178mm high (7 in). This level of density provides some important
advantages. First, it reduces the amount of switching hardware required for a given application.
Second, it provides high flexibility. The high density cards can be used with the special signal cards
to cover all your signal needs for a large application with one mainframe.
Switch a wide range of signals. The 7002 is fully compatible with all 7001 switch cards. From this
broad selection of more than 30 cards, you can assemble a switch configuration that will ensure signal
integrity and minimize errors. These cards allow the 7002 to switch DC signals from femtoamps
to amps, nanovolts to kilovolts, as well as RF and optical signals.
Analog backplane. The analog backplane used by the high density cards adds configuration
flexibility
and eliminates intercard wiring. For example,
the outputs of a multiplexer
card can be connected
to the row inputs of a matrix card. Or, the outputs of ten multiplexer
cards can be connected
to form
one large 1×400 multiplexer.
Intercard wiring is eliminated by using the analog
backplane to form
these configurations.
Faster Test Development
Unique channel status display. The interactive front panel display helps shorten the time required
to configure the 7002 and develop test software. The display indicates the open/close status of each
channel in the mainframe.
This information is very useful when programming the 7002 and developing
application
software. Knowing the channel status also helps to verify proper operation during the
debug phase.
Light pen programming. An optional light pen provides point and click programming
from the
front panel. By selecting the desired channels or range of channels, the scan list can be built, matrix
patterns created, channels opened or closed, and patterns stored in memory. The 7002’s non-volatile
memory stores up to 500 complete
switch patterns.
Automatic card configuration. When the high density cards are installed,
the 7002 automatically
configures each slot independently for the proper
card. The front panel channel status display adjusts to show each card’s
capacity and configuration.
Front panel Info key. At the touch of a button, the operator receives context-
sensitive, on-line information to help configure the system. This information
is displayed on a 52-character alphanumeric display for clear and
readable messages. There is no need to refer constantly to the operator’s
manual. All information messages, operating instructions, and prompts are
available in English, German, and French. Just select the desired language
in the configuration
menu.
Programmable channel closure restrictions. The 7002 allows specific
channels to be locked out from closure. This restriction can be conditional
based on the open/close state of other channels or crosspoints. This capability
is useful to prevent certain signals from being accidentally connected
to high power circuits, for example.
