SE1300 Series Module Lock-In Amplifier

Overview Specifications Ordering Resources

SE1300 series module lock-in amplifier is the latest core technology product, and it is a measuring instrument with high performance and high-cost performance. Based on digital modulation, output filter and high-precision 24-bit digital-to-analog converter (ADC), the new Zynq architecture can accurately and quickly measure the effective signal components submerged in large noise. Moreover, SE1300 series module lock-in amplifiers can simultaneously measure the amplitude and phase information of the input signal and are comparable to the top technologies in the same industry in the world in terms of core parameters such as measurement accuracy, operating frequency range, signal-to-noise ratio, and dynamic reserve. At the same time, functions such as multi-harmonic measurement, oscilloscope, and spectrum analyzer have been newly developed, so that the functions of SE1300 series can meet various scientific research and industrial purposes.
