Which ScopeMeters Will Display a Lissajous Pattern?
Not all Fluke ScopeMeters are capable of displaying a Lissajous pattern, also known as X-Y or A versus B. The 190 Series III, as well as older models such as the 190 Series II, the 19xC and 19xB models and even the 90 series scopes are able to display these patterns. The 120 and 120B models are not able to do this. There is no way to add this capability to the 120 or 120B ScopeMeters.
