The Advantest U3872 Cross Domain Analyzer is the industry's first metrology tool to offer phase measurement of two high-frequency signals in a single instrument, allowing operators to determine the phase difference. This new functionality enables quick and accurate detection of reception problems caused by inter-circuit interference or radio wave reflection, making the U3872 ideal for applications ranging from electromagnetic interference (EMI) challenges, to broadcasting and communications.
The U3872 series utilizes a new "X math" (pronounced "cross math") function for comparative analysis of input from two channels. This function displays the waveforms of both signals on a single coordinate plain, enabling operators to see the phase difference between the signals at a glance. Furthermore the U3872 can be used as spectrum analyzer.
