Multi channel FRA (Frequency Response Analyzer, Impedance Test) (M-FRA)

Multi channel FRAIntroduction to the instrument:
The frequency response analyzer with strong transmission force not only adopts the single sine wave correlation technology of *, but also uses a 26 bit frequency synthesizer with * resolution. Only ultra fine frequency scanning resolution can obtain precise impedance characteristics. At the same time, while meeting high-precision measurement requirements, 1455/1451 also adopts a multi wave FFT impedance analysis mode suitable for fast testing to meet different testing requirements.
The 1455/1451 series adopts a template design, which allows impedance modules to be added to multi-channel systems at any time according to needs. Each FRA module has an independent Ethernet communication interface, ensuring convenient and fast data transmission.

Multi channel FRAThe main characteristics are:
Single sine correlation technology: impedance frequency, 10 Hz~1MHz (1455)/100KHz (1451);
Multi sine wave FFT analysis technology: applicable to the entire frequency range, especially suitable for low-frequency testing;
High impedance accuracy and stability: 0.1%, 0.1 °
• Automatic integration technology: Based on the test results, optimize the testing time (integration noise reduction) to suppress the influence of noise and interference signals, achieving the ideal state of noise free and high-speed measurement;
Simultaneous measurement of anode/cathode impedance: Typically, battery and fuel cell testing systems can use auxiliary inputs for DC measurement, while the auxiliary channel (option) of the high load cell test system can perform simultaneous impedance testing on the entire battery system and its components. This technology is suitable for detailed and in-depth research on electrode materials, or for detecting the quality of individual cells in a fuel cell stack.
High power impedance testing: The voltage and current range of each channel in 1470 E is 10V/4A. If higher power battery packs or fuel cell stacks need to be measured, the Cell Test system provides parallel testing technology for DC and AC channels. The parallel DC multi-channel provides high DC load (up to 28 amperes), while the other channel does not have a high DC battery and only applies a small amplitude AC signal, achieving high sensitivity and high-quality impedance testing for high-power systems.
If it is necessary to increase the voltage testing range, a power amplifier with strong transmission force (1290) can be selected
