Broadband Component - Agilent Technologies 86038B User Manual

Broadband Component

(Isolator, Circulator, Coupler, Attenuator and so on)
Agilent 86038B Photonic Dispersion and Loss Analyzer, Second Edition
Characteristics
• Wide wavelength measurement range
• Usually low CD and PMD, but especially PMD may need to be
verified
• Loss may be high, but 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 dependencies of the attributes
being measured.
• If you use the smoothing function to reduce trace noise, you
may need to increase the number of trace points. (for
example, reduce the wavelength increment) to avoid loss of
resolution.
