The HF2LI is an advanced digital lock-in amplifier with an extended signal frequency range of 50 MHz. With its 2 physical input channels, it replaces 2 traditional lock-in amplifiers for measurement setups. The 128-bit digital signal processing delivers superior precision thus boosting both the noise performance and the dynamic reserve. With these unprecedented capabilities, the HF2LI brings lock-in amplification to a new level and enables new applications in a frequency range that was previously tied to analog instrumentation.
