q If the resultant trace starts at 1 MHz, HP-IB is functional in the analyzer.
Continue with “Troubleshooting Systems with Multiple Peripherals”,
“Troubleshooting Systems with Controllers”, or the “Step 4. Faulty Group
Isolation” section in this chapter.
q If the resultant trace does not start at 1 MHz, suspect the HP-IB function
of the analyzer: refer to Chapter 6, “Digital Control Troubleshooting.”
Troubleshooting Systems with Multiple Peripherals
Connect any other system peripherals (but not a controller) to the analyzer
one at a time and check their functionality. Any problems observed are in the
peripherals, cables, or are address problems (see above).
Troubleshooting Systems with Controllers
Passing the preceding checks indicates that the analyzer’s peripheral functions
are normal. Therefore, if the analyzer has not been operating properly with an
external controller, check the following:
n The
HP-ID
interface hardware is incorrectly installed or not operational. (See
“HP-II3
Requirements” in the
HP
8753E Network
Anulgzer
User’s Guide.)
n
The programmin
g syntax is incorrect. (Refer to the HP 8753E Network
Aruzlgzer Programmer’s
G&&e.)
If the analyzer appears to be operating unexpectedly but has not completely
failed, go to “Step 4. Faulty Group Isolation.”
