WitrynaThe SR510 and SR530 are analog lock-in amplifiers which 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. In addition, … Witrynaa Phase Meter a Spectrum Analyzer a Noise Measurement Unit …..and much more. It is this versatility, available in a single compact unit, which makes the lock-in amplifier … fieldstone architecture \u0026 engineering
