3.4.3 Two-mainframe system
Figure 3-13 and Figure 3-14 show a system using three
matrix cards in two Model 7001 mainframes to conÞg-
ure a 4 × 30 test matrix. This system is similar to the
Two-card System (see previous paragraph), except that
a third matrix card (installed in a second mainframe) is
added.
Figure 3-13 shows the connection scheme for the multi-
pin connector cards. External circuit connections to the
Model 7001 #1 mainframe are identical to the ones
used for the Two-card System. The third matrix card
(installed in Model 7001 #2 mainframe) shows how a
custom-built cable can be used to make connections to
external circuitry. A suitable round cable can be termi-
nated with a 96-pin female DIN connector (Model
7011-KIT-R) that will mate to the Model 7012-C matrix
card assembly. The unterminated end of the cable is
connected directly to instrumentation and DUT. Notice
that the row connections for the third matrix card are
made at the instruments.
Figure 3-14 shows connections for the screw terminal
connector card. Single conductor connections are made
directly from the screw terminals of the connector card
to instrumentation and DUT
3.5 Model 7012 installation and re-
moval
This paragraph explains how to install and remove the
Model 7012 matrix card assembly from the Model 7001
mainframe.
WARNING
Installation or removal of the Model
7012 is to be performed by qualiÞed
service personnel. Failure to recog-
nize and observe standard safety pre-
cautions could result in personal
injury or death.
NOTE
If using the screw terminal connector
card, make sure your external circuit-
ry is wired to the card (as explained in
paragraph 3.3.1) before installing the
card assembly in the Model 7001
mainframe.
CAUTION
To prevent contamination to the ma-
trix card that could degrade perfor-
mance, only handle the card
assembly by the edges and shields.
