WY2288 is an intelligent digital RF millivolt meter/low-power meter that can measure the effective value and corresponding power value of sine voltage with frequencies ranging from 200Hz to 1500MHz. It adopts the principle of detection amplification and has the characteristics of wide frequency response, low standing wave coefficient, high sensitivity, and high measurement accuracy. As a digital instrument based on CPU control, it realizes automatic range control and remote control function. It is an essential instrument for ultra-high frequency voltage and power testing and measurement in laboratory and workshop production.
