Agilent 86038B Photonic Dispersion and Loss Analyzer, Second Edition
The PDLA 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 PDLA 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
PDLA 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 PDLA Application. 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
PDLA application from the PDLA shortcut on the desktop, or
from Start Menu > Programs > Photonic Dispersion and Loss
Analyzer > Photonic Dispersion and Loss Analyzer.
The PDLA 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 PDLA. In order for the PDLA 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 the Agilent GPIB TNT Interface. This is
the correct configuration for the PDLA software to work
properly. DO NOT ENABLE the Agilent GPIB interface in the
Device Manager. Under National Instruments GPIB Interfaces,
