Functional module with built-in lock-in function that detects signals buried in noise and extremely weak signals. By combining a phase detector and a voltage-controlled phase shifter, a highly accurate 1- or 2-phase phase detector circuit can be configured.
| Phase detector series | A detection module that eliminates the effects of noise and converts a signal synchronized with an external reference signal into a DC signal. |
| Voltage phase controller series | Phase shifter module for phase detector reference signal |
| vector detector board | A unit board that combines a phase detector and a voltage phase controller to measure amplitude and phase using quadrature phase detection. |
