Using the 86122C Introduction The Keysight 86120D and 86122C Multi-Wavelength Meters measure the wavelength and optical power of laser light in the 1270–1650 nm wavelength range (700-1700 nm for 86120D). Because the instruments simultaneously measure multiple laser lines, you can characterize dense-wavelength-division-multiplexed (DWDM) systems and the multiple lines of Fabry-Perot lasers.
86120D and 86122C, use the new parameter EXT1 (CALC1:TRAN:FREQ:POIN EXT1). • Elevation: There is no need to enter an elevation for the 86120D and 86122C because they have an internal weather station. The command SENS:CORR:ELEV remains for backward compatibility, but has no effect on the 86120D and 86122C.
• Peak threshold: The 86120C peak threshold could only be set to a relative value. The 86120D and 86122C peak threshold can be set to a relative or absolute value. The command CALC2:PTHR:MOD allows you to select between an absolute or relative peak threshold, and CALC2:PTHR:ABS allows you to set the absolute value.
