“Step 4. Faulty Group Isolation” on page 4-10.
• If the result is not a copy of the analyzer display, suspect the GPIB function of the
analyzer. Refer to Chapter 6 , “Digital Control Troubleshooting.”
If Using an External Disk Drive
1. Select the external disk drive. Press .
2. Verify that the address is set correctly. Press
.
3. Ensure that the disk drive is set up correctly:
• Power is on.
• An initialized disk in the correct drive.
• Correct disk unit number and volume number (press to access the softkeys
that display the numbers; default is 0 for both).
• With hard disk (Winchester) drives, make sure the configuration switch is properly
set (see drive manual).
4. Press . Then press
.
• If the resultant trace starts at 1 MHz, GPIB is functional in the analyzer. Proceed to
“Troubleshooting Systems with Multiple Peripherals” on page 4-9, “Troubleshooting
Systems with Controllers” on page 4-9, or “Step 4. Faulty Group Isolation” on
page 4-10.
• If the resultant trace does not start at 1 MHz, suspect the GPIB 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:
• The GPIB interface hardware is incorrectly installed or not operational.
• The programming syntax is incorrect. (Refer to your analyzer’s programmer's guide.)
If the analyzer appears to be operating unexpectedly but has not completely failed, go to
“Step 4. Faulty Group Isolation” on page 4-10.
