The HPLIA series mini dual-channel lock-in amplifiers are designed with the industry-popular configuration of FPGA + ARM. In 2022, we have launched an upgraded version, HPLIA Plus, which supports an external reference signal input. A screen on top of the module displays the real-time status and data. The new features will help you achieve more flexible modulation and demodulation!
Customer cases:
2. A Prototype of High-Precision Carbon Isotopic Ratio Sensing System for CO₂ Dissolved in Water
Highlights!
1. External synchronization: The new HPLIA Plus supports external sync mode! The user can choose to synchronize the external input reference signal and use Input1 to demodulate the weak signal. The selection between internal and external synchronization modes is convenient for users to select modulation signals based on different experimental requirements flexibly.
2. A simple and economical multi-channel demodulation: In external synchronization mode, one of the modulation channels DDS outputs a sine wave phase-locked with the user reference signal, which can be used to synchronize other HPLIA Plus modules. This configuration makes multi-channel phase-locked demodulation possible by connecting several HPLIA Plus lock-in amplifiers in series.
Brand new UI: HPLIA PLUS supports both the PC display and the high-resolution touch screen on the module
