Isn't it better to understand that this is the way DSOs work.
Fixing it would require making all those low-end DSOs more expensive. You say you wouldn't mind if it all went slower in the name of accuracy but secretly you would. You'd be in here complaining about speed, and how your old 1990s Tek was faster.
Fungus, I'm starting to get seriously worried... You are a fungus, not a mushroom. Who keeps you in the dark and feeds ...? Rise up, break from the chains. You can do it, fight for your freedom
You remind me of beautiful russian women who are ok with drunk husbands beating them. It's not ok! There
is a better life out there
Don't suffer just because of having knobs!
Current Pico 2204A, costing just 109€ works just like my old 2205MSO and would wipe the floor with Z on low freq - because despite it has tiny 8kS memory, it actually uses all of it, not some 1.2kS interpolated down to a 300S(!!!) garbage!
What if we compare to actual counterpart 2408B, 100MHz, 4ch, 128MS. It's 128,000,000S vs 300S that scope can actually use for calculations...
But I know one other scope that you have to use just like Z - take measurements with cursors and scroll screen back and forth.
It's.... Velleman HPS140
Now about fixing part. Did adding "memory" source option to FFT make Z more expensive? Did you receive 39600$ bill?
Or what is cost of "<" adding sign before measurement value?
Also there's this option:
RUN mode - do as before, just display < or <= before readings or disable entirely.
STOP mode - switch to signal analysis based on actual sample memory.
No hit on realtime performance & valid data with single button press.
And not only measurements, it would make decoding work!So it's all about choices and not treating your customers like a mushrooms... Not so much about cost...
Yes there would be some programming involved but they already managed FFT so it's a broken in path...
And do not worry for me so much. I bought this box for very specific task at VHF freq.
According to
Screen sampling rate = 1 / (Timebase / 25) formula there is small window of timebases where Z can be used as more-less normal instrument: 5,10,20ns. So I'm very well covered with old Picos doing precision stuff below 25MHz and Z-box at VHF.
... but due to my pro line of work I feel that making society aware of s*it programming and it's implications is important so why not to have little cockfight now and then...
