Specifically, Yokogawa has added NORMAL/CHOP and MID/CHOP measurement sensitivity settings, which apply the lock-on 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 enables faster and more accurate measurements compared to the previous AQ6377.

The AQ6377E also offers expanded pulsed light measurement capabilities thanks to the addition of a new feature, 'advanced pulsed light measurement mode'. This enhancement provides engineers with improved ability to measure pulsed light at low repetition rates that were previously unattainable with the AQ6377.

In laser evaluation, simultaneous measurement across a wide range of levels was a distinct advantage of the previous AQ6377. The new AQ6377E improves upon this with a dynamic measurement range for simultaneous measurement of a laser's optical spectrum. This enhancement ensures that engineers can accurately evaluate the SMSR, a laser performance index, which is difficult to achieve with an FT-OSA.

The AQ6377E Optical Spectrum Analyzer is expected to meet CE marking requirements by the end of January 2025.
