D.E.V.I.C.E. is an encyclopedia of terms used by manufacturers of test and measurement equipment. T&M Atlantic created this service to better explain the functionality of instruments it offers, and to highlight the latest developments in the world of measurement equipment. We are using such tools as animation to bring words and pictures to life and to create not just an understanding but also an appreciation for technology that goes into the design of every instrument.

X-Y mode is a specialized two-channel mode of oscilloscopes when the signal of channel 1 is used for the deviation along the horizontal axis (X) and the signal of channel 2 – along the vertical axis (Y).
