EASY TO USE :The logarithmic power meter adopts AD8317 chip design, which is convenient to use, small in size, high in efficiency, easy to install, stable and reliable, and is used for radio frequency signal power detection..
DETECTABLE :The logarithmic power meter has strict quality control and quality assurance. It can detect the power of the radio frequency signal from -55dBm to 0dBm, and convert the radio frequency signal into a DC voltage output..
DYNAMIC RANGE :The greater the amplitude or power of the radio frequency signal, the higher the output voltage, and the output voltage is proportional to the logarithm of the input signal amplitude, thereby expanding the dynamic range of the detection signal to 55dB..
WIDELY USED :The logarithmic power meter adopts advanced technology and exquisite craftsmanship, and has been improved to improve durability. Logarithmic detector can be widely used in radio frequency signal detection, signal power measurement, and environmental field strength detection..
