Tokyo Instruments, Inc
About This Product
■Product overview
The SR830 (2-phase) digital lock-in amplifier is a low-cost, high-performance digital lock-in amplifier that uses DSP technology. The frequency range is 1 mHz to 102 kHz, and DSP technology realizes a dynamic reserve of up to 100 dB, making it possible to measure minute signals buried in noise with an extremely high S/N ratio.
■Features
・Frequency range 1mHz to 102kHz
・Dynamic reserve 100dB
・Auto Gain, Phase, Reserve
・Harmonic detection (2F, 3F, ..., nF)
・Equipped with digital demodulator
・With differential input ・With current input
・GPIB, RS232 interface standard equipment
■Applications
・Minimal signal measurement
・Signal measurement from photodetector (photomultiplier tube, PD, etc.)
・AC signal measurement
