Figure 2-20. Single Card System Example
2.7.2 Multiple Card System
Figure 2-21
shows a system using four matrix cards. Again,
instrumentation is connected to matrix card rows via the
quick-disconnect terminal blocks. However, these connec-
tions could have been made using a Model 707&MTC cable
if desired. DUTs are connected to columns using two
Model 70%Mx: cables cut in half.
2.7.3 Multiple Mainframe System
Figure 2-22 shows a system using eight matrix cards, re-
quiring two Model 7TJ7s daisy-chained together. In this con-
figuration all instrumentation and DUTs are connected to
matrix card columns using four Model 707SMlC cables
cut in half. A single Model 707%MTC cable is used to con-
nect the TOWS of the master mainframe to the rows of the
slave mainframe. Note that if path resistance is a critical
factor, use a cable that is as short as possible. A Model
7U7SMK cable can be shortened or a custom cable can
be built using two Model 7U7tXlT connector kits.
