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.
