Here's the issue.
Bought Keysight DSO-X 3000T series with appbndl enabled ca. 2 years ago. Wanted a quality instrument of all things.
In the spirits of the proverb "feel the pain when you pay for it or feel the pain every time using it" kind of thing.
Maybe 3 months into use, bam-hazam, scope hard-freezez during boot and wont just progress further.
Of course, this happens during such time where the scope is needed the most.
Issue was intermittent, so it took time before I finally sent it to Keysight for repairs.
The scope was repaired, calibrated and sent back. okay.
Now I have new issue. the thing won't trigger. Waveforms just run across the screen like crazy. Channel wont matter. trigger settings wont matter.
It looks like it needs significant warm-up time (15..20 minutes). Then, after this warmup or whatever, it starts triggering gradually over ca. 10s period. more and more until triggering becomes stable and issue goes away for another week or more.
Again intermittent. Possibly related to temperature (yeah,yeah, cold joint or smth, but that's for repairs section)
Naturally, I will send it back to Keyshight (oops) again but given the issue is intermittent, who knows what keysight will or wont do...
So, I'm pretty much fed up with that.
As the saying goes, First time, shame on you. The second time, shame on me ;(
Are Tek scopes any better than that?
Thinking of a ~350MHz 4channel 4000series 3 domains scope. Shariar has given thumbs up and that looks like good stuff.
Has anyone had similar quality issues with Tek scopes?
Should I expect any better from Tek?
