SRS SR530 — Analog lock-in amplifier Dual Phases

• 0.5 Hz to 100 kHz frequency range
  
• Current and voltage inputs
  
• Up to 80 dB dynamic reserv
  
• Tracking band-pass and line filters
  
• Internal reference oscillator
  
• Four ADC inputs, two DAC outputs 
• GPIB and RS-232 interfaces

The SR530 is a analog lock-in amplifiers which can measure AC signals as small as nanovolts in the presence of much larger noise levels.

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, the lock-in come equipped with a variety of features designed to make it simple to use.
