Standford Research SR810锁相放大器和SR830锁相放大器以合理的成本提供高性能。 SR830同时显示信号的幅度和相位,而SR810只显示幅度。两种仪器都使用数字信号处理(DSP)来代替传统锁相中发现的解调器,输出滤波器和放大器。The SR810 Lock-In Amplifier and SR830 Lock-In Amplifier provide high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal, while the SR810 displays magnitude only. Both instruments use digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins. 1 mHz至102.4 kHz频率范围 100 dB动态保留5ppm /℃的稳定性0.01度相位分辨率从10μs到30 ks的时间常数(高达24 dB / oct滚降)自动增益,相位,-reserve和-offset合成参考源GPIB和RS-232接口1 mHz to 102.4 kHz range100 dB dynamic reserve5 ppm/°C stability0.01 degree phase resolutionTime constants from 10 μs to 30 ks (up to 24 dB/oct rolloff)Auto-gain, -phase, -reserve and -offsetReference sourceGPIB and RS-232 interfaces
