ABSTRACT:
A lightwave component analyzer comprising at least an internal optical receiver and preferably also comprising an internal optical source which are selectively connectable by switches configurable by means of an internal or an external instrument controller for calibration and performance of electro-optical, opto-electrical, and optical measurements. The switches are arranged in a switch matrix. The configurable switch matrix is connected by the instrument controller in response to selection of a measurement by a user to facilitate calibration of, and test measurements of devices under test with, the lightwave component analyzer.
