The six-slot 707B and single-slot 708B Semiconductor Switch Matrix Mainframes extend Keithley’s decadeslong commitment to innovation in switch systems optimized for semiconductor test applications.
These mainframes build upon the strengths of their popular predecessors, the 707/707A and 708/708A, adding new features and capabilities designed to speed and simplify system integration and test development. New control options and interfaces offer system builders even greater flexibility when configuring high performance switching systems for use in both lab and production environments.
Just as important, both new mainframes are compatible with the popular switch cards developed for the 707A and 708A, simplifying and minimizing the cost of switch system migration.

Faster Command-to-Connect
High performance 707B and 708B semiconductor switch
matrix mainframes slash the time from command to
connection, offering significantly faster test sequences
and overall system throughput than Keithley’s earlier
707A and 708A mainframes.
Optimized for Easy Integration with
Existing Test Systems
To minimize migration issues for current users of 707A
and 708A mainframes, the 707B and 708B are designed for
command emulation with 707A and 708A. The 707B and 708B
also support the popular switch matrix cards developed for
the 707A and 708A, so there’s no need to purchase new cards
to take advantage of the new mainframes:
7174A Low Current
Matrix Card:This 8×12
card is designed for
semiconductor research,
development, and
production applications
that demand high quality
switching of I-V and
C-V signals.
Its low leakage and minimal dielectric
absorption ensure that key device measurements can be
performed many times faster than with earlier switching
technologies. Its superior low current performance
makes it ideal for use with both 2635B and 2636B System
SourceMeter®
SMU Instruments for adding high speed I-V
source and measurement capabilities and for accessing
the I-V and C-V measurement capabilities of the 4200-
SCS Parameter Analyzer.

7072 Semiconductor
Matrix Card:This 8×12
switch supports the low
level and high impedance
measurements
encountered in
semiconductor
parametric tests on
wafers and devices.
It provides two low current paths
with just 1 pA maximum offset current for sensitive subpicoamp measurements, and two other paths optimized
for measuring C-V characteristics from DC to 1 MHz.
Four more high quality signal paths with <20 pA offset
current provide for general-purpose signal switching up
to 100 nA or 200 V .

7072-HV High Voltage
Semiconductor
Matrix Card:Like the
7072, the 7072-HV is
designed to handle
low level, high voltage,
and high impedance
signals.
It provides two signal paths capable of switching
1300 V with less than 1pA of offset current, so it’s ideal
for switching the high voltage signals encountered in
breakdown measurements or oxide integrity testing.
Two paths are optimized for C-V measurements from
DC to 1 MHz or for switching low currents with a common
ground. Four additional high quality signal paths
with less than 20 pA offset current provide for signal
switching to 200 V.

Optimized for Easy Integration with
Series 2600B-Based Systems
The 707B and 708B are ideal companion products for
systems that incorporate Series 2600B instrumentation,
such as Keithley’s ACS and S530 integrated test systems.
These mainframes share the same TSP, Lua scripting
language, and TSP-Link interface as the Series 2600B
and support an ultra low current switch matrix (the 7174A)
that complements the 2636B’s low current sensitivity. The
707B/708B offer test system builders a switch matrix that
is fast, scriptable, and works seamlessly with all Series
2600B models.
