Hi,
A friend of mine gave me a PM3207 scope for free, and this
is the first one I am ever using. He told me some things may
not be working.
I am doing some basic tests, and nothing but noise appears
on the screen. I read a lot of doc about scope thus I dont
think I am missing the the point... so do you have a very
basic test for me to do? For instance, there is a ProbeAdj on
the front of the panel. When I connect my probe on it, I get
nothing (chan is the one selected, I used every time/div and
volt/div I could, results a re the same).
When I try to probe a 5v ttl gate, I get nothing too. When
I probe my ethernet RJ45 socket, I get a waveform, showing
that the probe is not dead.
Any idea?
Cheers,
t.
