The multi-channel lock-in amplifier features two independent, built-in digital PID controllers. Leveraging the high-speed processing capabilities of an FPGA, the PID sampling rate reaches up to 4 MSa/s. The PID algorithm is straightforward and intuitive; its control parameters are largely independent of one another, making parameter selection relatively simple. The PID controller delivers stable and precise control, adapting effectively to a wide variety of systems and efficiently handling dynamic system changes, thereby making it suitable for a broad range of applications.

In traditional lock-in amplifiers, only the fundamental frequency signal or a specific harmonic component can be measured at any given time. Consequently, for applications requiring the simultaneous measurement of the amplitude and phase of multiple frequency components, traditional lock-in amplifiers are unable to meet the necessary measurement requirements. The digital section of a multi-channel lock-in amplifier integrates FPGA and ARM technologies to achieve greater processing bandwidth and a more flexible digital architecture. It offers a digital processing precision of up to 48 bits and is capable of simultaneously analyzing up to eight input signals at arbitrary frequencies. Its eight demodulators can be freely configured for amplitude and phase, enabling linear combinations.

The oscilloscope features a 4 MSa/s analog input channel with a 3 MHz analog bandwidth, a 5 Vrms input voltage range, and user-configurable AC/DC coupling and 10 MΩ impedance.

The spectrum analyzer allows for the observation of input signals ranging from DC to 2 MHz in the frequency domain. Additionally, it features a resolution bandwidth as low as 1 Hz and a minimum span of 100 Hz.
