38 Keysight N778xB Getting Started Guide
1 Getting Started
Connecting the Instrument to the GPIB Interface
Connecting Tunable Laser Sources
Connect your TLS to the GPIB port of the N778xB/BD .
The polarizationNAVIGATOR™ software can communicate with Keysight
Tunable Laser Sources (TLS) either via the instrument's GPIB port (in that
case the instrument's GPIB port is used as GPIB-Master, see “Using the
N778xB/BD GPIB Interface (Remote GPIB)" on page 39 for details) or via a
GPIB board installed in your PC.
NOTE
National Instruments VISA has to be installed.
Use a standard GPIB cable to connect the N778xB/BD to the PC. On the
PC, VISA has to be installed to provide the GPIB functionality. Usually VISA
comes with your GPIB board, but may not be automatically installed on
your system. Check your GPIB board's driver CD or contact the vendor of
your GPIB interface for more information about VISA.
The default GPIB address is 30. Please refer to “Changing the GPIB
Address" on page 40 on how to change the GPIB address. You can check
the correct installation if you turn on the instrument and wait for some
seconds. Start the National Instruments Automation Explorer on your PC,
right-click the GPIB interface that the N778xB/BD is connected to and scan
for new instruments. The instrument should be detected on address 30.
You have to quit the Polarization Navigator software on the N778xBD to
put the GPIB port into non-controller mode. Only in this mode can you
control the instrument from outside. Otherwise the N778xBD uses the
GPIB port as
controller
port to control other instruments such as tunable
laser sources.
NOTE
When an N778xB instrument is connected to the GPIB bus, the Keysight
Connection Expert will display a warning icon next to it. You can safely
ignore this warning. Clearing this warning from the instrument’s details
view won’t prevent it from re-occurring immediately afterwards
