Ten-slot high density switch mainframe
SWITCHING & CONTROL
7002 Switch/Control Mainframe
400-Channel
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 40 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 40 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 con-
text-sensitive, on-line information to help configure the system. This informa-
tion 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 configu-
ration 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.

SWITCHING & CONTROL
7002 Switch/Control Mainframe
400-Channel
System Throughput
300 channel per second scanning. The 7002
can scan through up to 300 channels per second. This scan process can be controlled by the
internal time base of the 7002 or through external triggers. The scan sequence is controlled by
what appears in the scan list. The scan list can
include channels, ranges of channels, and memory locations. This approach gives maximum
flexibility while obtaining maximum throughput.
Built-in Scan Control and Trigger Link. The
built-in scan control eliminates the need for the
computer to control every step of the test procedure. Simply program the 7002 to control the
channel spacing, scan spacing, and number of
scans. Trigger Link gives you access to six independent hardware trigger lines on a single cable.
