I go away with the feeling that there are three things in Metrology, HP3458 and LT1001 and $75 resistors.
Nothing else matters or is allowed.
I can excuse your statement, due to fresh member effect
. Proper phrase should be "three things in metrology, Fluke 792A, Fluke 734A and ESI SR104". Truckload of rest M$ gear is expected as default.
Jokes aside on serious note, I don't quite see that much members here to bloat on having 3458A(/8508A/5730A/XXXXA/whatnot else) , like you suggesting to grant the "must have 3458 or you are not worthy" attitude
. It is probably just biased because people here (in metrology section of the EE forum) are biased and sucked into this hobby, so on average more of us have expensive meters, than usual electronics engineers, who don't need such meters for daily work.
If you looking for feedback on low-cost projects, that is fine too, if you don't take too everything that people post too personal. After all it's only this much once can do with low-cost part, that is designed and manufactured to meet it's spec (usually, take that VPG
, but it's bit much to ask for much better. Some go to great length doing sorting/matching/baking/cooking/soaking low cost part, be it resistor or voltage reference chip, but in the end it would be financially, time-wise and project wise CHEAPER just to spend those $5-75-250 on higher spec part that designed as such and not to worry. Now some of high-priced parts have issues and limitations too, so entering into realm of testing those limits and how to live with them is bit another matter, as it may help us to understand how to make things better. It is what some of nuts here about, taking something best commercial market can offer, and
attempting futile attempts trying to go step above.
Remember, lot of us here doing metrology toys and builds at home as a hobby, just for own amusement in free time, and often that extra hour of free time spent on soldering, measuring and documenting (taking photos and making post like this take time too!) is more expensive than even 75$ resistor. So think about return factor, what you are after, it is always a choice somewhere.
So yes, anything posted here will be critiqued and criticized in the effort to improve whatever the desired outcome is.
This! Also we already have General electronics talk, Test equipment, Repair and Projects sections. I see no reason why need to turn Metrology section into mix of these, posting general questions.
Back when I joined EEVBlog forums, all volt-nuts/ohm-nuts/time-nuts just hang out in T&M section and repair section, making all meaty threads that might be of interest for *nuts, but not so for general EE folk sink into abyss quick.
As refining Dave created dedicated subsection so bees are happy and separate from wasps and hornets now. So this supposed to be high-SNR area from the start, and members expected to have some level of understanding of things discussed.
