SR530 is an analog lock-in amplifier that can measure AC signals as small as nanovolts in the presence of much larger noise levels. Both the single phase SR510 and the dual phase SR530 have low-noise voltage and current inputs, high dynamic reserve, two stages of time constants, and an internal oscillator.
0.5 Hz to 100 kHz frequency range
Current and voltage inputs
Up to 80 dB dynamic reserve
Tracking band-pass & line filters
Internal reference oscillator
Four ADC inputs, two DAC outputs
