The Amrel IA integral impedance analyser is designed to work with the company's line of e-Load electronic loads, eliminating the need for a frequency response analyser, saving the customer more than $20,000 in additional test equipment. Designed to meet Amrel's e-Load customer's additional testing requirements, it serves as further indication of Amrel's ongoing commitment to its customers. Amrel's low-cost IA is unparalleled in features, flexibility and functionality.
The impedance analyser is designed to simplify applications in impedance measurement, electrochemistry (EIS) and fuel cell and battery testing/research.
For hassle-free AC modulation applications, the IA outputs an AC signal superimposed onto DC bias signal - to achieve operating currents up to 5000A DC.
User-friendly features include auto-gain control for accurate small signal measurement down to the micro-ohm range, saturation protection to prevent signal overload, auto-zero calibration for increased accuracy and auto-amplitude feature for ac modulation.
Precise control is available through configurable sampling intervals to balance between throughput and resolution, four display modes and operating current display, frequency and amplitude sweep displayed in Bode and Nyquist plots and V/I waveforms critical to EIS, and selectable gain control.
Full functionality is available through VFD display/full-functional keypad and via GPIB/USB/Ethernet/RS232 remotely using Amrel's application program.
The IA offers a frequency and amplitude range with accuracy of 0.1%, and distortion less than 0.1% to provide precise signal generation.
Impedance analysis applications can be realised through a frequency sweep of 0.1 to 20kHz and an amplitude sweep of up to 1V RMS and 5V DC bias, capturing critical test data down to the micro-ohm range displayed on a log/linear scale.
Only 1U high in size, Amrel's Impedance analyser packs a powerful and effective AC + DC sine generator.
