The pre-owned Advantest Q8344A employs a Michelson-interferometer Fourier engine to deliver 0.05 nm resolution across a wide 0.35–1.75 µm span, making it ideal for characterising CD/DVD, telecom and fiber-gyro laser diodes without external gratings. A built-in He-Ne laser reference locks wavelength accuracy to ±0.1 nm, while an 80 dB dynamic range and –70 dBm sensitivity capture ASE skirts and side-modes in a single sweep. Long-term stability, auto-peak and 3-D display functions streamline R&D and production, and each unit ships freshly calibrated—providing traceable Advantest precision at a fraction of new-instrument cost.
