Test Descriptions
3.8 ONLINE DATA TEST
This test section verifies the correct operation of the ABI to HP-IB logic (which consists of four HP-IB
transceivers and two inverters). It is assumed at this point that the PIC and the ABI have been completely
tested offline, so that all that remains to test is that the PIC can correctly communicate with other HP-IB
devices over the standard HP-IB.
A second PIC is required to perform this test section. The second PIC is assumed to
be
functioning
correctly, although some diagnostics are performed on it to avoid catastrophic failures. The two PICs are
connected together via HP-IB cables with no other HP-IB devices connected. Since some of the HP-IB
lines can only be asserted by the system controller, it is necessary for the PICDIAG to alternate the System
Controller function between the two PICs. This test is broken down into three groups so that failures can
be easily pinpointed.
Step 45. HP-IB Data and Control Test - At this point the PIC, the ABI, and all of the HP-IB drivers
have been tested. This test verifies that the HP-IB drivers work at high speed and tests the
pattern sensitivity of HP-IB interface lines. Additionally, it performs a general data and
control test similar to the DMA exerciser program.
