Low cost, high performance impedance analyzer

Design based on a digital lock-in amplifier using a Digital Signal Controller and two channel delta-sigma 16-bit ADC

Frequency range between 30 Hz and 10 kHz, with 1 Hz step

Impedance measurements between 100 mOhms and 10 MOhms

Automatic Level Control (ALC) for the signal applied on the device under test

Serial to USB adapter allows measurement from PC graphical interface

2x16 LCD shows relevant measurement information

In stand-alone mode can measure at 100 Hz, 1 kHz and 10 kHz, at 0.1 and 1.0 Vpp amplitude, selectable via buttons

Can perform 10 point frequency sweeps, average measurements and has variable measurement time (only through PC interface).
