General Information

1-3

Model 7076 Dual 4

12 Two-Pole Matrix Card

— The

Model 7076 is a general purpose matrix switching card that
consists of two independent 4

12 switching matrices. Each

matrix has two switched circuits (HI and GUARD). The four
row signal paths are connected through jumpers to the gen-
eral purpose analog backplane in the Model 708A. Connec-
tions to the matrix are through standard 25-pin D connectors
for mass termination.

Model 7077 8

12 Isolated Coaxial Matrix Card

— The

Model 7077 has 8 rows by 12 columns of two-pole Form A
switching for general purpose applications. It has BNC con-
nectors.

Model 7172 Low Current Matrix Card

— The Model 7172

is for semiconductor I-V and C-V measurements. It is con-
figured in an 8

12 matrix of two-pole switching with triax

connectors. An on-board electrometer measures offset cur-
rent.

Model 7173-50 4

12 High Frequency Matrix Card

—

This card combines high frequency performance with
excellent DC switching characteristics. It provides 200MHz
bandwidth in a 4

12 matrix configuration. It has BNC

connectors.

Model 7174 8

12 Low Current Matrix Card

— The Mod-

el 7174 is designed for high performance switching of I-V
and C-V signals. It has triax connectors.

Digital I/O cables

Model 7075-MTC Standard Cable

— Standard 3m (10ft)

cable assembly terminated with 25-pin D-sub plugs on both
ends.

CS-400 Cable

— 25-pin D-sub plug that will mate to the re-

ceptacles of the card. Solder-cup connections simplify the
building of custom cables.

CS-401 Cable

— 25-contact D-sub receptacle that will mate

to the cables terminated with a 25-pin D-sub plug.

CS-590 Cable

— Plastic backshell housing for CS-400.

Note: The following two cables are available from 3M Cor-
poration.

8225-7000 (3M) Cable

— 25-pin D-sub plug for customized

ribbon cable assemblies.

3357-9225 (3M)

— Junction shell for 3M 8225-7000 D-sub

plug.

Miscellaneous cables and accessories

Model 7007-1 Shielded IEEE-488 Cables

— The Model

7007-1 connects the Model 708A to the IEEE-488 bus using
shielded cables to reduce electromagnetic interference
(EMI). The Model 7007-1 is 1m (3.3ft) long and has an EMI
shielded IEEE-488 connector at each end. This cable is also
available in a 2m (6.6ft) length (Model 7007-2).

Model 7051-2 BNC to BNC Cables

— The Model 7051-2

makes connections to external trigger and matrix ready on
the Model 708A rear panel. The Model 7051-2 is a 50

Ω

BNC

to BNC cable (RG-58C), which is 0.6m (2ft) long. This cable
is also available in a 1.5m (5ft) length (Model 7051-5).

Model 7078-PEN Programming Light Pen

— The Model

7078-PEN connects to the Model 708A front panel. It is used
to toggle the states of the LEDs that display crosspoints and
digital I/O. A pen holder is included.

Model 8501-1 and 8501-2 Trigger Link Cables

— The

Model 8501-1 and 8501-2 contain an 8-pin male DIN con-
nector. The Model 8501-1 is 1m (3.3ft) in length, and the
Model 8501-2 is 2m (6.6ft) in length. Multiple cables are
used for connecting Model 708A units in a master/slave con-
figuration through the rear panel master/slave connectors.

Note: The following backplane expansion components are
available from 3M Corporation.

Backplane expansion (20-pin cable components)

3365/20 (3M)

— 28 AWG ribbon cable rated at >200VDC.

3461-001 (3M)

— 0.1 inch card-edge connector with a cur-

rent rating of 1A > 200VDC (one connector required for
each Model 708A).

3448-54 (3M)

— Strain relief.

Backplane expansion (50-pin cable components)

3365/50 (3M)

— 28 AWG ribbon cable rated at >200VDC.
