Abstract
A signal strength meter indicates signal level directly in dBmV. The signal under test is attenuated to a level which centers a meter indicator, and the attenuator movement is translated into numerical direct reading information of signal level. Push button switches select a channel for testing, and each switch incorporates gain compensation for the frequency of the signal to be tested. Within each channel the operator can select between audio and video carrier frequency.
