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.
