AnalogDiscovery2 I-V extention This is an educational instrument for practicing transport measurements.
One can learn basic operations of an I-V converter and a voltage amplifier,
and data acquisition with Analog Discovery 2 and LabVIEW.2 channels (I-V and Diff-Amp selectable) I-V: R_FB = (1k, 10k, 100k, 1M, 10Mohm) and C_FB = (10p, 1n, 100nF). Diff. amplifier: G = (1, 10, 100, 1000) Some test devices (n-FET, p-FET, Hall device) on the board. |
