*1: Waveform data of previous models (AQ-6315, AQ6317, and AQ6319 Series),
whose formats are .WV*/.TXT, can be used. The displayable wavelength range is 600-1700 nm, which is the measurable wavelength range of Optical Spectrum Analyzer AQ6370 and AQ6370B/C/D.

Analysis identical to AQ6370 Series can be performed on a PC. *2Major Analysis Functions of AQ6370 Viewer
*2 When reading the waveforms of an analyzer other than the AQ6370, the accuracy of analysis results and readings cannot be guaranteed with regard to power analysis, LED analysis, WDM analysis, EDFA-NF analysis, and conversion of the unit to dBm/nm (dBm is represented by the vertical axis.)
