Electric signal acquisition device for e.g. radar field, has digital encoders that perform sampling and analog/digital conversion of received signal to deliver digital data, and control unit that calibrates reference conversion voltages

摘要

The device has digital encoders e.g. analog-to-digital converter, provided for reception channels (V1, V2), respectively, and that perform sampling and analog/digital conversion of a received electric signal to deliver digital data. A processing and control unit (MT) has a test state in which the unit (MT) applies a reference input signal to the encoders and receives a spectral analysis of a converted signal at zero frequency. The unit (MT) has a normal operating state in which the unit calibrates reference conversion voltages and adjusts clock phases of the encoders based on the analysis.
