Comparison: AQ6317B vs Similar Models

• 
  

  Versus AQ6317 (non-B):
  The AQ6317B improves wavelength accuracy (±0.02 nm in C-band vs ~±0.05 nm in older versions), adds faster sweep times, and expands analysis functions such as optical filter testing and multi-channel noise figure evaluation.

  
  
• 
  

  Versus AQ6370C/D:
  Yokogawa AQ6370 series analyzers are newer successors with enhanced resolution (down to 0.02 nm standard, ±0.01 nm accuracy in models) and higher dynamic range in some configurations. However, the AQ6317B remains a reliable and cost-effective solution with strong performance across the 600–1750 nm range.
