Hi all,
Working on aligning another instrument last night, my scope - which I typically find extremely reliable for all the readings it's able to perform (from voltage/level to time-based and everything in between) - has been giving me some confusing readings. I could use some community "sanity checks" on my thinking here, please.?
Per enclosed scope screenshot (coming up), the rising segment of this triangular wave (which triggers a VCOs period) is in my book (per graticules indication) 120ms. And yet, the scope sees that as a 32.35ms risetime wave. The scope reading was rather fluctuating, but at no point coming even close to the 120ms I'd expect. Please note the period reading seems to be correct.?
Given the information presented on the image, when I was doing this last night, I decided to ignore the "risetime" reading and execute the adjustment I was required (120ms sweep time) as the image shows it.?
What could be going on here?.... Am I looking at this wrong? Or shall I start worrying that my scope is beginning to exhibit some sort of illness?
Thank you.?
Radu.?
