RE: My shiny new scope is broken :(

["Paul Gale" <groups@xxxxxxx>]

Don't think so - Ch2 works OK but not Ch1 - possibly a fault on Ch1. I
was wrong in that the 0V ref doesn't follow a 50Hz cycle - more curved
downward slope to around -1V and then returns eventually to 0V.

Sorry to hear that - silly question - but no chance the earth lead has
become disconnected is there ? That causes this effect.

After finishing playing with my nice new PC scope last night at
midnight, I came back to it this morning to find the recorded signals
on
channel A wandering all over the place (0V looks like it's superimposed
on a 50Hz cycle). Channel B is fine though. Pico are going to take it
back to repair it.



:-(
