Sometimes it is desirable to control more than one instrument from the same computer.
To do this you must have additional RS-232 ports available or you must install additional
RS-232 ports.
You have now several options: either you write your own operating software using one
of the available design software implementing as many RS-232 as needed, or, if you
use more than one Power Analyzer, open windows for all Power Analyzers and operate
them in parallel.
