A30 LISN Control Assembly Troubleshooting
A30 LISN Control Assembly Troubleshooting
Since the A30 LISN Control assembly has only one main function there are only
a few things that will need to be checked to verify that it is functioning
properly.
They are:
1.
Assembly Initialization
2.
Option LSN License Key
3.
Output Data Line Status LEDs
4.
Rear Panel AUX I/O Outputs
Assembly Initialization
Before the A30 LISN Control assembly will function properly it needs to
initialize itself when the instrument is turned on and be recognized by the
instrument software. The first step in verifying that this has happened is to look
at the instrument Hardware Information screen. To view this information press
System
,
Show
,
Hardware
. Once you do this you will see a listing of instrument
hardware assemblies that are installed. The A30 LISN Control assembly should
identify itself on this list as
General Purpose IO Control
. If this assembly does
not identify itself the cause for this will need to be determined before any other
troubleshooting is performed. The most probable causes for this type of a
problem would be:
— An instrument power supply voltage is not operating properly
Solution: Verify all instrument power supply voltages.
See
Chapter 12, “Power Supply & Midplane”
— A30 LISN Control assembly is defective
Solution: Replace the A30 LISN Control assembly
Option LSN License Key
While the instrument will identify the presence of an A30 LISN Control
assembly on the System, Show, Hardware screen without the presence of an
Option LSN license key, the assembly will not have the desired menus or
functionality without it.
To verify the presence of the Option LSN license key press
System
,
Show
,
System
and look for the presence of
N9038A-LSN LISN Hardware Support
. If
there is no entry for this a valid license will need to be obtained and installed.
