Details
on the measured signal :
This is a 40Gb/s mode
locked fiber laser measurement. The blue trace represents the 4ps pulse
generated by the mode-locked fiber laser, the red trace represents the
adiabatic chirp
(in GHz) of the mode-locked fiber laser and the yellow trace represents
the indetermined value of chirp (due to the low intensity power).
In this example, we measured a 40GHz mode-locked fiber laser coupled
to a 40Gb/s MZI modulator driven by a 40Gb/s pulse pattern generator.
The signal analyzed was a 16bits pattern.
AP2440A
benefits :
Based on our patented complex spectrum analysis principle, the AP2440A series
are only limited in temporal resolution by their wavelength range. So, temporal
resolution for pulse and chirp measurement is :
-
AP2440A maximum temporal resolution : 150fs
-
AP2441A maximum temporal resolution : 95fs
-
AP2443A maximum temporal resolution : 75fs
This makes
the AP2440A series, the ideal instrument for short pulse and chirp
measurement (transient and/or adiabatic chirp).
