# Ando AQ6317B Optical Spectrum Analyzer (Pre-Owned) # Ando AQ6317B Optical Spectrum Analyzer (Pre-Owned) ## Key Features At A Glance - Wavelength accuracy of ±0.02 nm (1520–1580 nm) after calibration with the built-in reference light source - Dynamic range of 70 dB at peak ±0.4 nm and 60 dB at peak ±0.2 nm for 50 GHz-spacing WDM signals - Maximum wavelength resolution of 0.015 nm (1520–1620 nm, 0.01 nm resolution setting) - High sensitivity measuring light down to −90 dBm across 1200–1650 nm - Direct high-power measurement to +20 dBm (100 mW) without an optical attenuator - Polarization dependency suppressed to ±0.05 dB for accurate optical-amplifier gain measurement - GP-IB (2 ports) plus TLS control and trigger interfaces for automated measurement systems - Three independent trace memories with a 9.4-inch color LCD The Ando AQ6317B is a high-accuracy, high-resolution optical spectrum analyzer built for evaluating dense wavelength-division-multiplexing (D-WDM) systems and components. It addresses a wide range of applications including light source evaluation, measurement of loss-wavelength characteristics in optical devices, and waveform analysis of WDM systems. The instrument achieves high wavelength accuracy and wavelength linearity in the C-band and L-band, suiting it to the evaluation of optical devices for WDM. An optical spectrum analyzer resolves an optical signal into its component wavelengths and displays power as a function of wavelength, letting an engineer characterize the spectral content of light sources and optical components. The AQ6317B applies this to specific WDM tasks: optical multiplexer (MUX/DEMUX) evaluation, yielding insertion loss, passband central wavelength, and linearity; and optical fiber amplifier (EDFA) evaluation, where the ASE interpolation method measures gain and noise figure. It also provides analysis for LD, LED, and FBG devices. ValueTronics stocks test and measurement equipment in its own 20,000 sq ft secure warehouse at 1675 Cambridge Drive, Elgin, Illinois. Because we hold inventory ourselves, every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. ## Brand Heritage Ando Electric Co., Ltd. was acquired by Yokogawa Electric Corporation in 2002, and its optical test and measurement product line subsequently continued under the Yokogawa name. ## Product Core & Specifications Specification Value Optical Specifications Applicable fibers SMF, GI (50/125 µm) Measurement wavelength range 600 to 1750 nm Wavelength accuracy ±0.02 nm (1520 to 1580 nm, after calibration with build-in reference light source); ±0.04 nm (1580 to 1620 nm, after calibration with build-in reference light source); ±0.5 nm (600 to 1750 nm) Wavelength linearity ±0.01 nm (1520 to 1580 nm); ±0.02 nm (1580 to 1620 nm) Wavelength repeatability ±0.005 nm (1 min) Wavelength resolution Max. resolution: 0.015 nm or better (1520 to 1620 nm, resolution setting: 0.01 nm); Resolution setting: 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1.0, 2.0 nm Resolution accuracy ±5 % (1300 to 1650 nm, resolution: 0.05 nm or more, resolution correction: ON) Measurement level range \-90 to +20 dBm (1200 to 1650 nm, sensitivity: HIGH3); -80 to +20 dBm (1000 to 1200 nm, sensitivity: HIGH3); -60 to +20 dBm (600 to 1000 nm, sensitivity: HIGH3) Level accuracy ±0.3 dB (1310/1550 nm, input: -30 dBm, sensitivity: HIGH1-3) Level linearity ±0.05 dB (input: +10 to -50 dBm, sensitivity: HIGH1-3) Level flatness ±0.1 dB (1520 to 1580 nm), ±0.2 dB (1580 to 1620 nm) Polarization dependency ±0.05 dB (1550/1600 nm), ±0.05 dB typ.
