Digital lock-in amplifier
Maturity plannedTargets FPGA + ASICDifficulty EasyPriority 2
Multi-harmonic digital lock-in with reference NCO, demodulation and selectable low-pass filters for atomic and optical sensing loops.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
