NEWMAN, Ga., March 16, 2014 — Yokogawa has released the AQ6370D optical spectrum analyzer for communications measurements in the 600- to 1700-nm wavelength range.
Its new functions include data logging, gate sampling, resolution calibration, an advanced marker function and an enhanced autosweep mode.
The data logging function records wavelength division multiplexing analysis results such as optical signal-to-noise ratio; the gate sampling function facilitates the recirculating loop testing of optical transmission systems; the resolution function calibrates the noise-equivalent bandwidth with an external light source; and the autosweep mode range has been extended.
The device is available in standard and high-performance versions. It has a wavelength resolution setting from 0.02 to 2 nm, a wavelength accuracy of ±0.02 nm (C+L band) and a maximum-level sensitivity of −90 dBm. The close-in dynamic range is from 70 (peak ±1 nm, resolution 0.05 nm) to 50 dB for the high-performance model (peak ±0.1 nm, resolution 0.02 nm). Stray-light suppression ratio is 70 dB or more, and sweep time is within 0.2 s for the 100-nm wavelength span.
