New scope

I have high end scope, but also a cheap low end

Picoscope 2204A costs 119 USD.

Also has FFT and a, lot of bus decoding features

If you need more bandwidth or channels the price increases...

Cheers

Ha! I Have a Trio CS1562A 10 MHz dual channel analog scope, and is all I ever needed at home. Fix your analog scope if you can!

There are cheap digital ones, USB PC is not practical. All depends on what you do. What counts most is understanding of what you do,

Well I designed and build scope-pic:

But if I needed a new scope I would go for a stand-alone, not a PC based one. Isolation for a start.

There are cheap Rigols some you could even modify in software to get more bandwidth IIRC Do not remember a model number right now, oh,

Does not J. Larkin have one?

The Analog Discovery 2 is very good. I have one I uses with an old Asus notebook PC running Linux, it makes a very portable and capable package.

I have a low end Hantek scope that works well except if trying to use the X and Y input function to use the Lisenjous 'circles'. I do have an old Techtronics scope for that .

Plus you get the added functions of an on screen digital volt meter and frequency counter. The 200 MHz scope is around $ 300 .

I would not fool with the hassel of the computer based scope things.

I like a scope with a screen and knobs. The Rigols are great. We haven't had trouble with one yet, out of a dozen at least.

Sharp color traces, infinite storage, cursors, time and voltage precision, signal averaging, all are wonderful compared to an old analog scope. And you can lift one with one hand.

So far, none of our digital scopes have needed repair. Analog scopes break a lot.

Not sure that goes, my Trio is from 1979 or so and only needed fixing after I accidently sparked to a channel from a TV booster tube. Was on all day for TV repair in my shop, is on here now every now and then:

Maybe, but they're all still young so it's not a fair comparison against say a Tek or a Philips or even a Hameg, many of which are still going strong 40+ years on. I can't see anything made in China lasting a fraction of that.

Any analogue scope made after about 1970 you should be able to lift with one hand! (and you can't have "infinite storage" either). --

Most of our old analog scopes died. I have a collection of big old Teks, few of which still work. Telequipments, Kikusuis, Philips, HPs weren't very reliable compared to modern digitals. There isn't actually much inside a 50 MHz scope now.

Failure rate on Rigols so far has been zero. I did see one at another site (Lily Drone, rip) with a smashed screen.

That quote is absurd. People like to own stuff. I bet that Schwab guy owns a lot of things in 2030.

The advantage is being able to store/process/recall the data and not just "see" it.

If you go that route, consider making a dedicated "appliance" instead of trying to remember how to run the "scope application" on a PC that already has dozens of other uses.

This costs only 200€£$ LABLOOT LB1202 Digital Storage Oscilloscope, 2 Channels 220Mhz Bandwidth 7''

Most do. We have one Tek scope with full isolation of all 4 channels and trigger, individually. You can clip the probe ground onto one side of the AC line, or the source of a mosfet 60 volts off ground.

Hello Sylvia, I was considering one of these just "for fun"

Otherwise my old Hitachi 35MHz is still fine (just bulky). Space is precious in modern city living...

Cheers, RS

Further examination shows that it's actually the corresponding transistor in the other half of the X-drive circuit. Which makes a warped kind of sense, so I will try replacing it.
