Available Configurations

The SR830 DSP Lock-In Amplifier provides high performance at a reasonable cost. The SR830 simultaneously displays the magnitude and phase of a signal. The instrument utilizes digital signal processing (DSP) to replace the demodulators, output filters, and amplifiers found in conventional lock-ins. The SR830 provides uncompromised performance with an operating range of 1 mHz to 102 kHz and 100 dB of drift-free dynamic reserve.


Features:

  • 1 MHz to 102.4 kHz frequency range
  • >100 dB dynamic reserve
  • 5 ppm/°C stability
  • 0.01 degree phase resolution
  • Time constants from 10 µs to 30 ks (up to 24 dB/oct roll off)
  • Auto-gain, -phase, -reserve and -offset
  • Synthesized reference source
  • GPIB and RS-232 interfaces
  • Interfaces: IEEE-488.2 and RS-232 interfaces standard. All instrument functions can be controlled and read through IEEE-488.2 or RS-232 interfaces.
  • Power: 40 W, 100/120/220/240 VAC, 50/60 Hz
  • Dimensions: 17" Å~ 5.25" Å~ 19.5" (WHD)
  • Weight: 23 lbs.
