Sometimes the threat of the Hammer is sufficient to make things fit or work appropriately yesterday a firm tappity tap tap got it done The difference in 0.1mm per face on just the Lid and Base even in this soft materiel matters.
Even I cant bring myself to suggest @Brumby (not that far from him) should chase this poor orphan, no probes and already done to death by likely any trash handheld gimmick scope on evilbay is it already over priced at $0.99 eBay auction: #203469404981
The oval knobs are impressive!
All levity aside, it looks similar to the single channel version I have.
Quite a while back I bought it to help troubleshoot my BWD 'scope, which had faulty triggering.
It worked, & I found the fault.
The hard bit then, was getting into the congested "guts" of the BWD to replace a 200 k
resistor that had decided it wanted to be 1.5 M
instead.
Apart from the tiny screen, & the fact it looked like it was meant to be operated by "Cabbage Patch" dolls, the little 'scope was just as capable as the BWD, so that got "chucked in the shed" & left for a later date.
The wee beastie was my main, & only 'scope for some time, till I picked up my Tek 7613 from a hamfest.
The single channel analog Digitech, in my opinion will "run rings around" all the little "pretend" handheld 'scopes you will find, for one reason:-
"Subterranean level" DSOs of that type have the same silly problems that bedevilled early DSOs from more legitimate manufacturers, which are, lack of memory, & catastrophically reduced sample rates at long time/div settings, causing horrific aliasing.
The little analogs may only have a 10MHz "3 dB down point", but it remains the same, whatever the time/div setting.
