The Stanford Research Systems SR865A Lock-in Amplifier is the latest in a line of innovative amplifiers. With strong analog performance, sophisticated new digital signal processing features, a thoroughly modern, intuitive user interface, and a wide range of computer connectivity options, the Stanford Research Systems SR865A is the ideal choice for any synchronous detection application. The instrument comes with a toroidal transformer that eliminates switch-mode noise. This amplifier is iOS compatible, connecting your cell phone to the data the system provides.

The Stanford Research Systems SR865A offers both state-of-the-art voltage and current input amplifiers. The voltage input is a switchable single-ended/ differential JFET-pair amplifier with 2.5 nV/√Hz of noise at 1 kHz and under 10 nV/√Hz of noise at 10 Hz. The voltage input has a 10 MΩ input impedance and can be AC or DC coupled. Input connector shields can be connected to the instrument ground through a user-selectable 10Ω (Ground) or 10 kΩ (Float) resistor.
