Dual multiplexer application
This application demonstrates how to use the Model 7700 as a dual multiplexer to bias and
measure 10 DUT. An external source powers DUT, while the DMM of the Model 2700
measures the output of the DUT. To prevent overloading of the external source, each DUT
is powered (and measured) separately.
Figure 2-9 shows the connections for this application. The external source is connected to
the Sense terminals of the switching module, and DUT is connected to channels 1 through
10. Channels 11 through 20 are used to connect external power to each DUT.
