The AQ6377E offers a number of new features and functions that enhance speed, accuracy, and capability, enabling it to meet a broader spread of laser application demands, including environmental measurement.
A successor model to the AQ6377, the AQ6377E optical spectrum analyser presents users with a number of new functions and specifications.
For example, the AQ6377E offers improved performance of the built-in chopper, which operates automatically according to the measurement sensitivity setting. Specifically, Yokogawa has added the NORMAL/CHOP and MID/CHOP measurement sensitivity settings, which apply the lock-in detection function to the intermediate NORMAL and MID sensitivities of the previous model. This capability reduces the impact of background noise when measuring MWIR light spectra and allows faster and more accurate measurement compared with the previous AQ6377.
The AQ6377E also offers much wider pulsed light measurement capabilities thanks to the addition of a new function, ‘advanced pulsed light measurement mode’. This enhancement provides engineers with improved ability to measure pulsed light with low-repetition frequencies.
In laser evaluation, simultaneous measurement over a wide level range was a clear performance advantage of the previous AQ6377 model. The AQ6377E adds to this with a dynamic measurement range for the simultaneous measurement of a laser’s optical spectrum. This improvement ensures engineers can accurately evaluate the SMSR, an index of laser performance, which is difficult to achieve with an FT-OSA.
The AQ6377E is planned to meet the CE marking requirements by the end of January 2025.
