Built-inEIStest

Built in AC impedance spectroscopy test, instrument with built-in direct digital signal synthesis（DDS）The sine wave excited by the circuit is an AC impedance signal. cooperate, coordinate, collaborateEIS300The subharmonic sampling technology of the software package can enable the AC impedance frequency range of the instrument to reach5MHz-10MHzDue toReference 620Provide flexible and wide current range, which can accurately measure impedance values from10^L12Ω to10The study of any electrochemical system, especially high impedance systems, can address challenges such as corrosion, coatings, and sensors.

Excellent low-noise design

Selected electronic components and meticulous circuit design, as well as intelligent filtering and circuit protection technologyReference 620low noise<10MV rmsWhen testing current, voltage, and auxiliary input signals, circuit combinations were cleverly introduced to reduce noise levels. High speed sampling and equalization techniques were used to smooth the test and obtain curves with high noise levels. During high-speed sampling, the host used60kHz（16.6Ms/point）Speed sampling, square the number of sampling points to reduce measurement noise.
