HF2IS Impedance Spectroscope

Request Information

The HF2IS is the solution you require for dynamic and static impedance spectroscopy. Two differential measurement units with a wide frequency range and 4 dual-phase demodulators, are matched with the unprecedented precision of a 128-bit DSP engine. This permits to perform multi-frequency measurements with very high sensitivity and precise static impedance characterization combined in one fully-digital benchtop instrument. These capabilities satisfy the highest impedance measurement requirements of leading research laboratories.

HF2IS Available Options

HF2IS-MF Multi-frequency

The HF2IS-MF multi-frequency option impressively extends the capabilities of your HF2 Impedance Spectroscope, by adding 4 additional demodulators and a wide range of configuration options. This greatly improves the flexibility of the instrument and as a result greatly enlarges the research horizon of scientists. The aim of this capability is to replace a great number of instruments with only one. Zurich Instruments is the only hardware vendor who has mastered this feature.

HF2IS-RT Real-time

The HF2IS-RT option consists of a programming environment that enables the user to implement customized software on a powerful embedded Microblaze® processor inside the HF2IS. Plenty of resources to support complex algorithms are provided. This is for instance required by RT (real-time) applications needing fast reaction based of input signal changes. The processor runs free of interrupts and the timing behaviour of the software is inherently robust and reproducible.

HF2TA Current Amplifier

The HF2TA current amplifier converts 2 input currents into voltage output in a wide frequency range up to 50 MHz. This device is an active probe which can be conveniently placed close to the measurement setup. It supports most applications where a current must be converted to a voltage. The dedicated design of the HF2TA ensures stability and a smooth operation over the entire frequency range.
