8-10 Triggering

External triggering example

For a test system that requires a large number of switching channels, the Model 2701 can
be used with external scanners such as the Keithley Models 7001 and 7002. For example,
10 Model 7011s installed in the Model 7002 can provide up to 400 2-pole channels, as
shown in
Figure 8-6

The Trigger Link connections for this test system are shown in
the Model 2701 is connected to Trigger Link (either IN or OUT) of the Model 7002. Note
that with the default trigger settings on the Model 7002, line #1 is an input and line #2 is
an output. This complements the trigger lines on the Model 2701.
For this example, the Models 2701 and 7002 are configured as follows:
Model 2701
Factory defaults restored (accessed from SHIFT-SETUP)
External triggers (accessed from EX TRIG)
Buffer enabled and set to store 400 readings
