2.7.3 Wide Matrix Expansion
Figure Z-17. Table 2-8 summarizes the wide (eight rows)
matrix possibilities for a single Model 707 mainframe.
By installing the cohmn jumpers of the Model 7076, the
card becomes configured a.5 an 8 x 12 matrix (see para-
graph 2.42). Assuming that the backplane jumpers of the
Model 707 and 7076s are installed, each 8 x 12 matrix card
installed in the mainframe extends the matrix by 12 col-
1111~1s. For example, three Model 7076s konfigured as 8 x
12 matrices) installed in the Model 707will result in an 8 x
36 malxix. An example of an 8 x 36 matrix is shown in
With the column jumpers installed, column 1 is con-
netted to column l', column 2 is connected to column 2
and so on. Thus, when connecting DUT or instmmenta-
tion to the columns of the matrix, it is recommended that
only one column's receptacle be used.
