Group 6–DMA
This group tests the DMA Channel 2 and memory-to-memory DMA
transfers. Table 5-8 gives the test numbers and names of the DMA tests.
Group 7–68881 Coprocessor
This is a test of the numeric coprocessor operation. If the 68881 is not
installed, the GPIB-VXI/C skips this test. Table 5-9 gives the test number
and name of the 68881 Coprocessor test.
