Ordering Information
7709 6×8 Matrix Module
Accessories Supplied
Two mating IDC connectors
Use with Integra Series mainframes: 2700, 2701, 2750
The Model 7709 plug-in module is a twopole, 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.
CAPABILITIES
DMM CONNECTION:
2-Wire Functions
Row 1, channels 1–8, through channel 50.
4-Wi re Functions
Row 1, channels 1–4 (Source) through channel 50 and
Row 2, channels 13–16 (Sense), through channel 49.
CLOSE CHANNEL: CLOSE command connects channels 1–8 to
DMM. For 4-wire, channels 1–4 are automatically paired with
channels 13–16. ROUTe:MULTiple allows any combination of
rows and columns to be connected at the same time.
