(Isolator, Circulator, Coupler, Attenuator and so on)
Agilent 86038A Optical Dispersion Analyzer, Third Edition
Characteristics
• Very wide wavelength measurement range
• Low dispersion and DGD
• Loss relatively independent of wavelength
Measurement Tips
The broadband nature of these devices allows you to trade off wavelength
resolution for faster measurement speed.
• Set the modulation frequency in manual mode to 2000 MHz.
• In either swept or stepped mode, optimize measurement speed by setting the
wavelength increment just small enough to resolve the wavelength dependen-
cies of the attributes being measured.
• If you use the smoothing function to reduce trace noise, you may need to in-
crease the number of trace points. (for example, reduce the wavelength incre-
ment) to avoid loss of resolution.
