Two-Phase Lock-In Amplifier 1 mHz - 102 kHz.

The Stanford Research SR830 is a Lock-In Amplifier and provide high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal. It use digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins.

The SR830 provide uncompromised performance with an operating range of 1 mHz to 102 kHz and 100 dB of drift-free dynamic reserve. IEEE-488 and RS232 interfaces are standard.

Frequency range: 1 mHz to 102 kHz

Dynamic range without pre-filtering: 100 dB
