4.12 DUT test system using two switch-
ing mainframes
The following example explains how to configure and oper-
ate a DUT test system using two switching mainframes
(7001s) and a DMM (2001 or 2002).
Assume there are four 10-channel multiplexer switching
cards (Model 7156 General Purpose Mux Cards) installed in
the switching mainframes (two cards in each mainframe) for

a total of forty 2-pole channels. This test system (shown in
Figure 4-30) will scan and measure the forty 2-pole channels
twice (two scans). The Trigger Link connections for this test
system are shown in Figure 4-31. For this example, the
DMM and switching mainframes (7001s) are configured as
described in the following paragraphs.
