The project was proposed by a group of students from University of Ljubljana.
Original proposal is located HERE. Below is the copy/paste of the proposal:
The expected specifications of our instrument are the following:
- 100Hz to 500kHz continous frequency range
0.5% basic measurement accuracy
the device will be able to measure 10 impedance parameters
4terminal Kelvin connections
automatic parametric frequency sweep
default or custom test signals:
default - AC voltage, programmable from 20mV to 0.5V
custom - transient voltage signal with max amplitude: +- 0.5V, can be imported or included as a transfer function
DC bias voltage 0.5V
test frequency accuracy +- 0.02Hz
manual calibration for short/open connections
graphical interface includes results shown in plots and tables
can calculate the average of up to 100 measurements
manual/automatic and smart data acquisition functions
