Re: [Phys-l] Help With Lissajous curves

[Brian Whatcott <betwys1@sbcglobal.net>]

Amplifying Dennis's input: The front panel control can be a sweep 
time/division
selection on the front panel marked ext, which selects a front panel
Ext Input socket(on B&K Scopes) or a back panel socket for the same purpose
(on some Tektronix scopes).

Z (brightness) inputs are often accommodated in a similar way.
