User Interface Reference 5
• : If it is not already running, this starts the LCA server. If it is
already running, it brings the server to the foreground.
• : With the LCA SCPI Configurator you can configure the SCPI
connection interface (socket or USB) and start or stop the
SCPI interface.
The LCA SCPI Interface does not start automatically. To enable control
of the LCA using SCPI commands you have to start the LCA SCPI
interface manually.
To launch the LCA SCPI Configurator, you may either press the "LCA
SCPI Configuration" button in the network analyzer GUI macro list
under "Utilities", or use the shortcut "LCA SCPI Configuration" which
you can find on the desktop or in the program menu.
For information on further function keys, please refer to the documentation
supplied with the network analyzer.
NOTE
After completing the “LCA Measurement Setup” step, the network
analyzer is ready for DUT measurements.
Because the receiver responsivity depends on the optical power, you
should start the DUT measurements with the LCA “Single” or
“Continuous” macros.
These macros perform an optical power measurement prior to each
measurement sweep. This achieves the highest accuracy in EO
measurements.
If you do not need this accuracy, you can also start the DUT
measurements with the network analyzer's trigger functions.
In some cases it can become difficult to abort continuous measurements
by pressing the "Continuous" or "Single" button, since the network
analyzer does not react to the keypad during measurements. In that case,
abort the measurement with the "Abort Measurement" button in the LCA
Server window.
