ABSTRACT:
A lightwave component analyzer including at least an internal optical receiver and preferably also including an internal optical source which are selectively connectable by switches configurable by means of an instrument controller for calibration and performance of electro-optical, opto-electrical, and optical measurements. Transmission measurements of E/O devices are corrected for source match errors, and transmission measurements of O/E devices are corrected for load match errors, in addition to frequency response and cross-talk error correction. Response and match error correction provides for improved measurements of test devices with an electrical port having an impedance different from that of the measurement system impedance.
