Request InfoAPEX TechnologiesApex Technologies has launched the AP264XB optical complex spectrum analyzer, which can function as both an optical modulation analyzer and as an optical spectrum analyzer for various testing and measurement applications. The instrument can measure any modulation format and any baud rate cycling signal modulated with a PRBS (pseudo random binary sequence) pattern or a long pattern. Its measurement speed is about 1 Hz. It can separately and simultaneously measure two polarization axes and analyze Pol-Mux modulated formats. As an optical modulation analyzer, it can measure chirp,...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra May 2024 IssueLaser SpectrometerThe TDLS8220 from Yokogawa Corporation of America is an extractive tunable diode laser spectrometer for extractive oxygen measurements where in-situ or probe-type installations are not applicable....Photonics Spectra November 2022 IssueTunable LaserThe T200S tunable laser from EXFO Inc. is a continuously tunable device for cost-optimized testing of transceivers and optical components in high-volume manufacturing.
