openQCM Q-1 Shield for Teensy 4.0 - Evaluation Board
This device is provided as a custom-built R&D kit and is not CE marked, nor certified for EMC or FCC compliance. It is intended exclusively for research use by qualified personnel in controlled laboratory environments. See [details] for further information.
openQCM Q-1 shield is a powerful Quartz Crystal Micrbalance (QCM-D) evaluation board based on network analyzer, designed for more advanced applications using Quartz Crystal Microbalance Technology (e.g. dissipation measurements).
The openQCM Q-1 electronics is mainly based on a scalar network analyzer, which is able to passively interrogate the device under test in a wide range of frequencies and analyze the transmitted signal in terms of gain and phase.
The shield uses an AD9851 DDS/DAC Synthesizer clocked at 120 MHz, which is able to generate a sine wave signal between DC and 50 MHz. The signal passing through the quartz crystal sensors is analyzed by AD8302 RF/IF Gain and Phase Detector which is able to simultaneously analyze both the gain loss and the phase delay.
NOTE: Teensy shield is shipped with all components mounted. Teensy board not included.
