Troubleshooting GPIB Communications Problems
4. Ensure that the GPIB setting in the PNA software is set to talker /
listener
5. Ensure that NI GPIB driver is enabled, Agilent GPIB driver is disabled.
Agilent 86038A Optical Dispersion Analyzer, Third Edition
The ODA is based on Agilent's performance network analyzer platform.
The two instruments use GPIB in different ways. In the PNA software, the
GPIB on the instrument can be set as a talker / listener, so that the
instrument can be controlled remotely over GPIB. The PNA software can
also be set to control other instruments remotely over GPIB.
The ODA uses the GPIB as a controller, to communicate with the tunable
laser source and multi-wavelength meter. If the GPIB settings have been
changed in the PNA software, the ODA will no longer be able to
communicate with the other instruments.
To check the GPIB setting in the PNA software, first exit out of the ODA
Application (File > Exit > "agilentoda" > Yes). Then, launch the PNA
software from C:\Program Files\Agilent\Network Analyzer\835x.exe.
When the PNA software loads, go to System > Configure > SICL/GPIB ...
From the SICL/GPIB setup panel, ensure that under GPIB, the talker /
listener radio button is selected, and the address is set to 16. Close the
panel, and exit the PNA software. Open the ODA application from the ODA
shortcut on the desktop, or from Start Menu > Programs > Agilent Optical
Dispersion Analyzer > Agilent 86038A.
The ODA is based on Agilent's performance network analyzer platform.
The two instruments use GPIB in different ways. Both Agilent GPIB TNT
Interface and National Instruments GPIB Interface are present on the
ODA. In order for the ODA to communicate with the tunable laser source
and multi-wavelength meter, both of these device drivers must be present.
In the device manager, (Start > Settings > Control Panel > System >
Hardware > Device Manager), you will see a listing for GPIB Devices,
under which the Agilent GPIB TNT Interface is listed. There will also be a
listing for National Instruments GPIB Interfaces. When the GPIB Devices
listing is expanded, a red X will appear in front of Agilent GPIB TNT
Interface. This is the correct configuration for the ODA software to work
properly. DO NOT ENABLE the Agilent GPIB interface in the Device
Manager. Under National Instruments GPIB Interfaces, the AT-GPIB/TNT
interface will be enabled. This again is the correct configuration for the
ODA software to work properly. If the device settings have been changed,
please restore them to the condition described above for the system GPIB
to function properly.
