A Detector Log Video Amplifier (DLVA) is a specialized electronic device used in radar receivers, electronic warfare, and signal intelligence applications. It consists of a detector and a logarithmic video amplifier. The detector converts incoming RF signals into DC voltage, while the logarithmic video amplifier compresses a wide dynamic range of input power levels into a narrower range of output voltages. This compression simplifies the analysis of signals with large amplitude variations. The primary purpose of a DLVA is to provide a consistent output proportional to the logarithm of the input signal power, aiding in the visualization and analysis of RF signals.
