Yokogawa AQ6370B 600-1700nm Optical Spectrum Analyzer

The Yokogawa AQ6370B Optical Spectrum Analyzer sets a benchmark in optical test instrumentation. Engineered to deliver high-precision spectral analysis, it features a wide measurement range of 600 nm to 1700 nm and boasts an exceptional wavelength resolution down to 0.02 nm.

Complementing this, the instrument supports a measurement level range from –90 dBm up to +20 dBm, enabling both very low-level and high-power optical signal inspection.

The AQ6370B also offers outstanding dynamic range performance — for example, 62 dB or more in a ±0.4 nm region at 0.05 nm resolution.

In terms of usability and throughput, the system delivers fast measurement speeds (on the order of 1 second or less over a 100 nm span) and supports modern interfaces including USB for storage, GPIB/RS-232/Ethernet remote control, making integration into automated test setups straightforward.

Whether your application is DWDM channel analysis, component validation, EDFA gain profiling, or semiconductor laser characterization, the AQ6370B provides the precision, speed and reliability you need. With its robust benchtop design and Yokogawa/Ando legacy, you’re investing in a test instrument built for demanding optical measurement tasks.
