Second connect test
This connect UTM connects the device to the PGU and the GNDU. In the project navigator,
double-click the second
connect test to open it. Figure 4-49 shows the parameters that connect
the device to the PGU. Not shown is line 1 (OpenAll) that opens the relays closed by the previous
connect test. Line
1 is shown in Figure 4-47 .
For the parameters shown in Figure 4-49 , the device connection pathways to the PGU and GNDU
are shown in Figure 4-50 . Remember that if your physical matrix connections are different, you will
have to change the connection parameters in the UTM to match them.

pgu1-init test
In the project navigator, double-click pgu1-init to open the test. This one parameter test (see
Figure 4-51 ) initializes the PGU. For example, it disables the output, resets errors, and sets
triggering. More information about the initialized state is provided in the description area of the
definition tab. For details about the UTMs for the pulse generator, refer to the
Reference Manual,
Pulse generator test example, Appendix F .
