tech,
My apologies, I have no idea how that got into my head. I presume you know it was not intentional.
Goddamn it. I had taken the time to write a reply and I got timed out. Also, this message system has no undo button !
Moving on. Ya larned me some stuff!! Thank you.
It seems we have a little in common. We both like to clear away the bullshit.
It looks to me like you get joy from helping others learn. That has been the focus of my website since 1999 (Front Page!!), although not updated sine we moved to New Hampshire.
That site (
www.historictimekeepers.com) is the reason I got invited to a year in Switz at WOSTEP at the age of 56. I try to give the "kids" some hints about what to avoid and various ways to accomplish the job. I even have some hidden documents that I share only with those who are intently interested. As most might guess, "watchbreakers" are not particularly knowlegeable about their craft, let alone first principles. I even have one document l that describes watch precision in terms of "Q". You might be shocked to know many watchbreakers do not know their craft, let alone first principles.

I do appreciate you taking the time to help me with this. I am not one who feels "entitled" to the knowledge of others. Sharing that knowledge is a gift to the recipient.
OK. I am 70 and not feeling challenged by my craft. I am starting to get hand tremors and know the time I have left is limited. So, SMDs are out.
I decided to create a course of self study in EE. Art of Electronics, USN NEETS (which I was taught in HS before they eliminated circuit analysis), Diligent You Tube and Kahn Academy (mainly for calculus at this point).
Because of this group, I avoided some serious mistakes in building my learning lab. I have built my lab around an Instek GPS 4303, the Discovery, three Fluke 8040a's and HP 3478a that all agree, the Siglent scope for under $1K including my Amazon wall power strips (learned not to screw around after 40 years of evaluating useless tools in watchmaking). I also have a Lambda LK 351-FMOV that has served me well over the years but is now best used for chest presses.
In the process, I have been shocked by how the world has changed. Online compilers for Fortran,Cobol,and Python! When did THAT happen? I remember punch tape, punch cards, and Word Star! Budgeting for computer time. I cannot believe the equipment today compared to 1970 when the Simpson 360 was the"gotta have".
So, I AM serious and appreciate your help.
I think your advice enabled me to get useable information off the Siglent when used as a CT.
But I still have two questions. One is the thickness of the lines in the curves. Is this a resolution issue? I understand this is a beginner's scope.
Why the loss of screen real estate?
I am still confused about Sa/sec/Mpts/KPI. Is there a place I can read up on them? Seems like it might be useful to understand.
Below is screen print (thank you) of the trace that seems to work. I can measure with the cursors. BTW, I was not worried about the relative position of the 0,0 because all measurement is relative. And I was lining up things to interpret the graticule.
Is there a way to improve the resolution short of replacing the scope I just bought?
Any thoughts on the limitations of the Discovery Analog 2? Seems to solve the AWG and digital measurement issues.
Regards,
Dewey
