The U3800 builds on the success of Advantest's U3700 series of spectrum analyzers, launched in October 2008, whose two-channel input option was also an industry first. With this function, enabling two signals to be monitored in tandem, the U3700 was widely embraced by customers. Now, Advantest has launched the U3800 series in response to customer feedback requesting additional functionality, providing the ability to simultaneously measure the phase of two signals for more efficient identification of noise sources.
The U3800 also enables multi-pass analysis, Ａnd greatly simplifies the process of identifying Ａnd suppressing EM radiation noise. The U3800 series utilizes a new "X math" (pronounced "cross math") function for comparative analysis of inputs 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.
The U3800 is available in three configurations with varying frequency ranges Ａnd price points, allowing customers to Ｓelect the product that best meets their needs.
