No, it does not do that. The specs say up to 6kHz but to be honest, at first glance I can’t interpret the numbers very well, have dive into that some time. And build up the lightsensor-handscope circuit (as described in Terry Oregon’s thread) to check it against.
I did check the spectra it produces with a helium lamp though, perhaps nice to see, the peaks are dead-on the nanometer (which I think is the most important parameter for the numbers it calculates to be correct), but the wavelength resolution is not as high as I would like to see (of course).
Pic from the internet with peak wavelengths:
The heliumlamp that I measured behind a slit and photographed through a diffraction grating (my phone camera appears to not pick up light over 670nm):
The spectrum produced by the Mavolux Base:
