YB-CD333 series products are set up by power measure at same trade; it is the special design for Data TV transport with high function and convenience taking. With the epoch of Data TV coming, there’s a new subject request for businessman, how to measure and analysis QAM, QPSK waves right and dependable? Now we can deal with those questions such as any wave power and amplitude efficiency and cheap by the measure technique of real power. The core of Data TV transport is channel power, S/N, C/N etc.  Traditional instruments are set up through measure wave simulate electro circuit, and perfect by the way of “figure replace measure”, so, not only the way of measure but also precision are all can’t perform the request of target measure. YB-CD333 series had considerate fully and practices in order to perform the request of simulate TV to Data TV. YB-CD333 series products are endow with a new errand to satisfy modern measure by the using of power testing technical, and at the same time it decrease the dependence about expensive and complex of simulate circuit. So, YB-CD333 series products have the best system on the function and price.
