The compact, half-rack design of the Model 7001 conserves precious
rack space without sacrificing capability or ease of use. Its interactive
front panel provides maximum functionality. This design makes it
quick and easy to develop, verify, debug, monitor, and control an
application. The Model 7001 also provides built-in scan control,
accommodates the industry’s broadest range of signals, and won't
degrade signal integrity. If an application outgrows the Model 7001, it's
simple to move it to the Model 7002 because both systems are
software-compatible and share the same family of switch/control cards.

Features:

• Automatic card configuration. Just insert a card in a slot and the
Model 7001 does the rest.

• Built-in scan control eliminates the need for computer control,
providing higher production throughput.

• The Trigger Link function makes it easy to trigger multiple
instruments within a test system without computer interaction,
increasing speed and production throughput.

• Channel-status display and full control keypad shows the status
of each channel simultaneously, making it easy to monitor or
configure a test system, modify programs, and verify proper
operation during debugging.

• Digital I/O available on the rear panel and on many
switch/control cards.

• GPIB bus ensures reliable, high speed communications.

Specifications:

• Supports up to 80 channels or matrix crosspoints
per mainframe.

• Includes two card slots.

• Holds 100 discrete channel patterns in non-volatile memory.

• Scans 165 channels/second.

The two slots in the Model 7001 mainframe
support a family of more than 40
switch/control cards for routing the industry’s
widest range of electrical and optical signals
for production test and sensitive
measurement applications. These cards make
it easy to assemble a switch configuration that
will ensure signal integrity, minimize errors,
and prevent degradation due to offset voltage,
isolation resistance, and leakage current.
