Wzmacniacz homodynowy (lock-in) DSP (1 mHz do 102 kHz) – Saluki SE1022
Opis
SE1022 Digital Lock-in Amplifier provides an excellent performance within its bandwidth from 1 mHz to 102 kHz. With the advantage of the latest digital signal processing technology and high-precision 24-bit ADC, SE1022 can easily detect the phase and the magnitude of weak signals overwhelmed by various large noises. The performance of SE1022 is as good as other lock-in amplifiers brands, even better in some certain parameters, such as measurement accuracy, SNR, dynamic reserve. Otherwise, SE1022 integrates some special functions like multiple harmonic measurement and FFT, which meets the needs of scientific research and industrial application well.
* Saluki SE1022 can be comparable to SRS SR830, even better and more stable.

Application of Lock-in Amplifier in TDLAS Technology
TDLAS is a detection technology that can realize the measurement of gas component concentration. The lock-in amplifier is used to achieve the second harmonic detection of the modulated signal.
In this system, the most critical part is to use the lock-in amplifier to realize the two-way detection of the measured gas and the reference gas at the same time, and even need to realize the three-way detection of the measured gas, the reference gas and the laser. The multi-channel harmonic measurement function of SE1022 can solve this problem perfectly.
