Hi, I've been reading this group for some while now and there seems to be some good advice given in amongst the bogus posts, spam and flame wars.
Anyway, I have plenty of xp repairing scopes but I just got 2 Tek 2230's in with the same problem, so I'm wondering if its just me or something I missed previously.
On slow timebase setting say 2mS with readout on but not storage, I'm getting interference on the trace, like the alphanumeric data is strobing the trace. On faster timebase speeds no problem. I was wondering if anyone out there has a 2230 they could take a look at and see if this is just a design fault, its odd to get 2 of a kind, in fact I was thinking its me being daft, and went around turning off the flourescents in the workshop in case it was just interference strobing, but no joy. Power rails are all clean. Incoming mains is clean. Nothing else electrically noisy in the workshop.
So if you have a 2230, put it to single trace, (or dual on Alt), around
2mS timebase, readout on, and tell me do you get interference on the trace? Like unsynchronised dark spots running through.Email address is bogus so please reply through the group.
Thanks in advance. JC
