A '''vectorscope''' is a special type of [[oscilloscope]] used in both audio and video applications.<ref>{{cite book |last1=Bairagi |first1=Vinayak |last2=Munot |first2=Mousami V. |title=Research Methodology: A Practical and Scientific Approach |date=30 January 2019 |publisher=CRC Press |isbn=978-1-351-01325-3 |page=210 |url=https://books.google.com/books?id=5tKFDwAAQBAJ&pg=PT210 |language=en}}</ref> Whereas an oscilloscope or [[waveform monitor]] normally displays a plot of signal vs. time, a vectorscope displays an [[Oscilloscope#X-Y mode|X-Y plot]] of two signals, which can reveal details about the relationship between these two signals. Vectorscopes are highly similar in operation to oscilloscopes operated in X-Y mode; however those used in video applications have specialized graticules, and accept standard television or video signals as input ([[demodulation|demodulating]] and [[demultiplex]]ing the two components to be analyzed internally).
