The SR810 (single phase) and SR830 (dual phase) DSP lock-in amplifiers from Stanford Research Systems have a frequency range of 1 mHz to 102.4 kHz, and provide 100 dB of dynamic reserve without pre-filtering. Output time constants range from 10 µs to 30 ks, with 6, 12, 18 or 24 dB/oct rolloff. A low distortion (-80 dBc) synthesized reference source is standard, as are GPIB and RS-232 computer interfaces.
