6×8 Matrix Module
accessories supplied
Two mating IDC connectors
The Model 7709 plug-in module is a two-
pole, 6×8 matrix module . It can connect any
combination of six differential channels of
instrumentation to any combination of eight
differential device-under-test channels . The
instrumentation can be AC and DC sources,
internal or external meters, oscilloscopes, etc .
This matrix configuration allows wide flexibility
for complex test systems .
Minimum signal level 10mV, 10µA .
