AD8362 True RMS level measuring meter circuit is as shown. The AD8362's output voltage is directly sent to the digital voltmeter (DVM). It should be noted that it belongs to the voltage level meter because the DVM reading is proportional to the measured rms voltage’s logarithm. And the meter’s display unit is dBv. During the measurement for high frequency RF input signal, the following measures should be taken: one is to increase the input decoupling capacitor (or RC decoupling network) and the other is to minimize the length of input signal lead, decoupling capacitors lead and ground wire.
