GPIB-VXI User Manual
The DIP Switch and Trigger test interactively tests the operation of the onboard DIP switches
and trigger circuitry.
The DMA Test
The DMA test performs tests on DMA Channel 2 to ensure that DMA memory-to-memory
transfers are functional.
The 68881 Coprocessor Test
The 68881 Coprocessor test tests the numeric coprocessor operation. If the 68881 is not
installed, the GPIB-VXI skips this test.
Diagnostics Mode Selection
Three hierarchical levels of menus control execution of the diagnostic tests. The highest-level
menu is the Diagnostics Mode menu, which you can use to select whether to execute a test group
or step group, and the mode in which to run them. The Diagnostics Mode menu is shown in
Figure 5-1 and described in Table 5-2.
