Running test sequences
NOTE For detailed information about test and sequence execution, refer to the Reference
Manual, Run execution of individual tests and test sequences, page 6-162 .
The ivswitch project uses the same ITMs that are used in the default project. The primary
difference between the two projects is that the ivswitch project uses connect UTMs to control the
switch matrix. As shown in
Figure 4-13 , there is a connect UTM at the beginning of each device
test sequence.
A test sequence for a device is executed by selecting the device plan, and then clicking the green
Run button .
When a device plan is started, the connect test closes the appropriate matrix crosspoints to
connect the instruments to the appropriate device.
All devices may be tested by selecting the Subsite Plan and clicking the green Run button .
Figure 4-14 through Figure 4-18 show the signal paths that are automatically selected for the five
devices.
