Overview
The high-performance OE1022 DSP Lock-In Amplifie provides a cost-effective solution for the customers. Based on the digital demodulation, output filter and high-precision stabilized 24-bit ADC, it is ideal to detect the weak signals, which are overwhelmed by greatly larger noise components. And the OE1022 could measure the magnitude and phase of a signal simultaneously, which is necessary for some scientific experiments. This versatile instrument uses Field Programmable Gate Array (FPGA) to recover the fast changing signal more precisely. The OE1021 offers satisfactory performance over an operating frequency of 1 mHz to 100 kHz.
