The inexpensive design in the implementation of the logarithmic probe is based on a small number of components, mostly discrete. It complements the design of the AVT5580 generator-wobulator (EP2-3 / 2017). The logarithmic probe allows measurements in the range from low frequencies (acoustic) to RF. (about 40 MHz).
