AQ6317B OSA Capture with Prologix GPIB-USB

Runs a single trace on an ANDO OSA connected via Prologix GPIB-USB controller.

OSA_Prologix.m runs and plots a single scan based on current settings of
the ANDO AQ6317B.
Connection is based on the COM (USB Serial Port) identified in the
Prologix GPIB Configurator. See here:
