Providing high-quality performance at a reasonable cost, the SR810 Lock-In Amplifier displays magnitude while the SR830 Lock-In Amplifier simultaneously displays phase and magnitude signal..以合理的成本提供品的性在放大器SR830定显示器sr810大小相放大器同时显示相位和幅值的信号。Both of these instruments use signal processing which can replace output filters as well as demodulators and amplifiers which may be found in more conventional locks ins.两种仪器使用的信号处理可以代替出滤波器以及器和放大器可在更传统的INS发现。
