Improvement of the digital signal processing module

Metrological characteristics of the APC 216 digital signal processing module, part of the A17 spectrum analyzer, have been significantly improved. Now the dynamic range is 130 (!) DB at a sampling frequency of 25 Hz and 106 dB at a sampling frequency of 25 kHz.

A program has been written that can be used as part of a multifunctional control system for shaker stands and will allow to fully automate laboratory tests when measuring metrological characteristics and verifying the vibration settings, various parts, and mechanisms for vibration effects of various origins. A new program – a generator with feedback – automatically ensures the maintenance of a given load on the shaker in the required frequency range.
