SECTION 1
General Information
1.1 INTRODUCTION
This section contains general information
about the Model
7072 Semiconductor
Matrix
Card. The Model
7072 is
designed for flexibility
in switching
semiconductor
test
setups. Two low-current
pathways, and two C-V pathways
in addition
to four general-purpose
pathways allow com-
plete system versatility.
tion. When returning
the matrix card for repair, be sure
to fill out and include the service form at the back of this
manual in order to provide
the repair facility
with the
necessary information.

8 x 12 (eight row by 12 column)
switching
matrix.
l
Two rows (A and B) with low-current
offset for low-
current measurements.
l
Two dedicated rows (G and H) for CV measurements.
l
Three-lug triax connectors for all row and columns allow
guarding of each signal pathway to minimize
the effects
of stray capacitance,
leakage current,
and leakage
resistance.
The
WARNING
