2.7 TYPICAL CONNECTION SCHEMES
The information in this paragraph provides some typical
connection schemes for single card, multiple card and
multiple mainframe system configurations. All of the
following examples show Model 7078~MTC cables cut in
half. Keep in mind however, that in systeiw where path
resistance is critical, cables should be kept as short as
possible.
2.7.1 Single Card System
Figure 2-20 shows how external connections for a single
card system might by made. Instrumentation is connected
to matrix card Tows. Using standard instrument cables that
are unterminated at one end make it convenient to make
connections at the quick-disconnect terminal blocks of the
matrix card. Instrumention uses only four rows allowing
the rest of the rows to be used by DUTs. A Model 7UZWfK
cable cut in half, is then used to connect DUTs to matrix
card columns and the remaining rows.
