Abstract
A measuring device for measuring signal strength of an RF signal received by an antenna includes a measurement unit, a processing unit and a display unit. The measurement unit includes a band-pass filter for filtering an antenna signal received from the antenna, an amplifier for amplifying the filtered signal according to a gain value, and an RF log detector for outputting a voltage signal according to power level of the amplified signal based on a logarithmic slope. The processing unit obtains a strength signal according to the voltage signal, the gain value and the logarithmic slope. The display unit displays an indication of the signal strength of the RF signal according to the strength signal.
