Configuration

40
If you start the LCA SCPI interface and configure it to run on the USB
device port, you will get the identification string for the LCA instrument
when you send the *IDN? SCPI query.
However, if you run the LCA SCPI interface on the socket port and have
connected your PC via USB with the LCA instrument, the network analyzer
identification string will still be returned.
After a system reboot, the USB device port is always taken by the network
analyzer SCPI interface by default. The LCA SCPI interface has to be
started manually. If you run the LCA SCPI interface on the USB device port
and want to switch to the socket port, you have to stop the LCA SCPI
interface first, then change the configuration to socket port and save it.
This action will restart the network analyzer application automatically, to
reclaim the USB device port for the network analyzer. Now the LCA SCPI
interface can be restarted with the new configuration.
GPIB port
The LCA SCPI interface doesn't support the GPIB port. However you may
control the network analyzer application through SCPI over the GPIB port.
This gives you the possibility to control the instrument independent of LAN
by controlling the LCA application through SCPI over USB and the network
analyzer application through SCPI over GPIB.
Select the communication port for your LCA SCPI interface, either the LAN
socket port 5026 or the USB device port. Run the
Agilent.LCA.SCPI.Config.exe program or click on the LCA SCPI
Configuration shortcut on the network analyzer macro list to select the
preferred port. The LCA SCPI talker/listener runs on the socket port 5026
by default. The port is not selectable to avoid conflicts with the network
analyzer SCPI interface, which runs on port 5025.
For support purposes, you may turn the logging on or off. The logging
stores all program outputs into a file. Note: it may fill up your hard disk if
you run the SCPI interface in logging mode for a long time.
When done with configuration, click the "Save Config" button to store all
settings. After saving the settings, the LCA SCPI module will adopt the
modified configuration when you click on the "Start SCPI" button.
