DS¥lock-in amplifiers

Sept. 1, 1995

The Model 7260 and 7220 lock-in amplifiers use digital-signal-processing (DSP) techniques to improve gain, accuracy, and output stability. The amplifiers provide operation over more than eight decades of frequency range and offer both current and voltage signal inputs. Both models can be controlled via an RS-232 port or an IEEE interface. The Model 7220 can be supplied with a blank front panel to OEMs or users who plan to control it exclusively by computer.
