Lock-In Amplifier SE2041 DSP (Single-channel)

Lock-In Amplifier SE2041 DSP (Single-channel)

SE2041 Digital Lock-in Amplifier provides an excellent performance within its bandwidth from 1 mHz to 60 MHz.

With the advantage of the latest digital signal processing technology and high-speed 250MSPS 14-bit ADC, SE2041 can easily detect the phase and the magnitude of weak signals overwhelmed by various large noises.

The performance of SE2041 is as good as other lock-in amplifiers all over the world, even better than them in some certain parameters, such as measurement accuracy, SNR, dynamic reserve, which meets the needs of scientific research and industrial application well.

Application of Lock-in Amplifier in Biomedicine

Higher frequency bands and greater sensitivity for measuring the electrical impedance spectroscopy of cellular and subcellular components have been made possible by the advancement of biomedicine. Currently, the most efficient technique for electrical impedance spectroscopy measurement is to build a microfluidic device with a digital lock-in amplifier.

The impedance cytometry technique is suitable for observing the size and velocity of cells in microfluidic channels. It is based on monitoring changes in the dielectric properties of cells as they pass through two electrode pairs in a microfluidic channel. It has a fast response time, no tagging and integrates classification operations.
