High-performance power measurements by sample-and-hold AC/DC transfer technique
B. Stojanovic, F. Herrmann, M. Stojanovic · IEEE Transactions on Instrumentation and Measurement · 1999
An ac/dc transfer method is shown based on the analog sample-and-hold principle, as well as the implementation of a new device, the TTTS power sensor. This gives possibilities for a simple design of a power measuring system with an accuracy of several tens of ppm within the frequency range of hertz to megahertz.
