The HF2IS is the instrument of choice for dynamic and static impedance spectroscopy. Two differential measurement units with a wide frequency range and 4 dual-phase demodulators are matched with the precision of a 128-bit DSP engine. This opens the way to multi-frequency measurements with high sensitivity and precise static impedance characterization combined in one fully-digital benchtop instrument.
This product was discontinued; users interested in similar functionalities may wish to look at the MFIA 500 kHz / 5 MHz Impedance Analyzer and at the HF2LI Lock-in Amplifier.
