--- Quote from: beanflying on June 01, 2018, 06:17:35 am ---I managed for over 20 years post Uni without a scope of any sort apart from an occasional drop around to 'borrow' a little time on one. About 3 years ago brought a piece of Hantek USB CRUD which was better than nothing but in hind sight I should have sought out a clunky 20Mhz Analogue of some sort which would have been as accurate and not crashed every other minute  :horse:.

Now owning a Migsig 100Mhz Toy would I go back to using an Analogue one day to day - unlikely. I did buy a fixer upper Philips 20Mhz as a play thing and to hack together a curve tracer circuit to dedicate to it at some stage but not for everyday use and I cant see me ever putting money at a high end Analogue ever.

As to day to day use mine is more like weekly or even every other week  :o I blame the lack of more frequent use to not having owned one for a very large part of my post Uni life and I am used to getting by without one still.

Todays Project just for fun putting the smoke back into my Dad's old Growler so I can use it as a degausser (100W anyone want any data erased?  >:D ) Smoke reinstalled into the new switch 40 year old failed masking tape removed and nail polish added to the partially unwound and rewound coil where it arced out. No CRO was needed in this repair  :-DD

Not because they neglected to break, but because their owners intentionally chose them over a DSO? Can you still buy CROs in meaningful numbers and with relevant specifications? How many does Keysight sell each year?

Good question...

A quick search shows that TEquipment and Arrow both still sell Analog scopes; mostly B&K school-grade gear, though Arrow does have a couple TFT-screen analog models by LeCroy.

I can tell you that our local hackspace has both analog & digital scopes, and the EEs who work and produce commercial product from the space both keep a couple analog scopes apiece on carts in their arsenals, outside the motley collection in the public spaces. But both of them are old-timers like myself, so they're probably not a good representation, even though they are technically still professional EEs.

Of course there are cheap DSOs all over the place; they swarm like mosquitoes in a place like that. ;) And at least half of them still work.  [emoji14]  We have a couple Adafruit wannabes doing their thing there too.  :-+


Tautech, I skimmed over Defpom's video on your 1202X-E; I like it overall.

While it does appear quite responsive, I don't see a lot of difference in the usability of the UI vs my 1054Z. I really only notice responsiveness issues on mine when I'm working with multiple signals and decoding; for the usual daily driver stuff, it's pretty much right there with me. For folks who need the extra BW, your 1202X-E is clearly a better choice in this price range; but I think part of what makes it more responsive is it only has to contend with 2 channels and 10K less memory depth. For most of what I need a DSO for, 4 channels is a minimum and I sometimes still wind up dragging out the Salae clone and my tablet.

So it's nice to have a choice in the bottom bracket, depending on what your primary needs are.


Cheers,

Rapid Electronics in the UK are still selling new CROs, 20MHz 2 ch and 100MHz 2 ch ones, I have one of their 25MHz 2 ch ones myself.

I'm not sure if anyone else is selling any, perhaps I might do a scan on the Web later

We have a lab auction going on of a research company and the only scopes they used are high end CROs so it would seem that they are still in use commercially.

--- Quote from: tautech on May 31, 2018, 11:55:32 pm ---And yet in this day and age there are still some that insist your first scope must be a CRO,  ::) it was for me and I learnt a ship load but a DSO is a more capable tool.

--- End quote ---

The reason it's a better tool to LEARN on is the usually-linear relationship between what you configure, what you're measuring and the results you see on the screen. Once you understand the fundamentals, which the CRO is better at teaching hands-down, then you're ready to wrap your brain around more advanced diagnostic techniques; some of which a DSO is better at, and some the CRO is still better at.

As I've said before... the "one or the other" argument is just plain stupid. Each excels at different things, and decent CROs are cheap and plentiful enough that there's simply no good reason NOT to have both on your bench.

Precisely.

And in response to tautech's point, "And yet in this day and age there are still some that insist you cannot do anything useful with a CRO, and that 100MHz is sufficient with modern logic".

bd139:
Indeed. 100MHz is certainly pushing it with modern logic. It’s only good for me because at best I’m using a 16Mhz or so clock and the result of that is much slower. If you have an Intel Core on the bench, out comes your £100k scope :)

A CRO is perfectly useful. Just a DSO is more useful over a larger problem domain. A CRO is a good learning exercise. I recently sat with an EE student in front of a Rigol DS2000 series unit and it was confusing for him. YMMV but I’d like to see some DSOs on the market with an interface as good as the old 54600’s.

med6753:
All this talk about CRO's being obsolete has got my boys in full revolt.  :rant: They want to kill the Siglent DSO which is currently in hiding.  :scared: Please assure them that they still have a function on the bench. I tried and they won't listen.  :-// I'm afraid if this continues much longer they'll start releasing magic smoke.  |O

Please help!   :phew:
