REAL TIME FREQUENCY AND DISSIPATION MONITORING

The measurement process involves assessing frequency, phase, and monitoring dissipation, founded on the analysis of the quartz’s Lorentzian resonance curve. The software commands the DDS synthesizer to passively excite the quartz crystal near its resonance frequencies, while concurrently obtaining amplitude raw data from the gain/phase comparator. This setup facilitates the real-time capture of the resonance curve, thereby enabling instantaneous monitoring of both frequency and dissipation.

The Teensy development board is fully compatible with Arduino programming language and environement. Take advantage of the simplicity of coding and the endless resources shared by the community for programming your scientific device. Based on FreqCount library developed by Paul Stoffregen the computing capability of the 180 MHz Cortex-M4F microcontroller allows frequencies up to 65 MHz to be measured.
