HP-II3 Failures
If you have performed “Step 3. Troubleshooting HP-B3 Systems” in Chapter 4,
“Start Troubleshooting Here,” and you suspect there is an HP-IB problem in the
analyzer, perform the following test. It checks the internal communication path
between the A9 CPU and the Al6 rear panel. It does not check the HP-IB paths
external to the instrument.

• If the analyzer fails the test, the problem is likely to be the Al6 rear panel.
q If the analyzer passes the test, it indicates that the A9 CPU can communicate
with the Al6 rear panel with a 50% confidence level. There is a good chance
that the Al6 rear panel is working. This is because internal bus lines have
been tested between the A9 CPU and A16, and HP-IB signal paths are not
checked external to the analyzer.
