The Agilent/Keysight 8703B Lightwave Component Analyzer characterizes optical and electro-optical components with calibrated measurements across optical and electrical domains. It performs optical transfer function tests, reflection performance analysis, modulation bandwidth measurements, and polarization-dependent loss characterization. The instrument supports 1601 trace data points and applies temperature-compensated calibration with error-correction algorithms to minimize systematic errors and ensure measurement repeatability. Measurement sequences can be memorized with calibration steps and paused for connection changes, then saved as instrument states or recalled for automated routines.
