>If they only knew about Partnered Output Coils! The Cost! WOW! The dismantling when it comes time to retire is phenomenal! I am at a loss to believe why so much money would be spent on such things, then the cabling into the Grid! The alternative (for them) would be to dismantle... Everything. Back to the topic, is a 'pocket' oscilloscope (e.g. https://m.aliexpress.com/item/32974331378.html?src=google&_randl_currency=GBP&_randl_shipto=GB&src=google&albch=shopping&acnt=494-037-6276&isdl=y&slnk=&plac=&mtctp=&albbt=Google_7_shopping&aff_platform=google&aff_short_key=UneMJZVf&gclsrc=aw.ds&&albagn=888888&albcp=1622677378&albag=57224001810&trgt=743612850714&crea=en32974331378&netw=u&device=m&gclid=EAIaIQobChMIpv2ruNyQ6AIVhsjeCh3CiAKzEAkYDyABEgIMp_D_BwE worth bothering with, or are there other ways of visualising waveforms while I save for a full size one?

I am not able to make recommendations on Hardware, if you see it want it and think it will do the job, then I have to say, best to make your own mind up as you alone can make the decision on if it will do what you want it to do.
Hi Andrew, for a while (few years) me and Cd_Sharp used pocket oscilloscopes DSO203 made by SainSmart.
I just checked and seems sainsmart.com don't have these models in their offer anymore (they have more expensive variations now) but I see some similar devices with lower prices on AliExpress: https://www.aliexpress.com/wholesale?catId=0&initiative_id=SB_20200310132413&SearchText=dso203
These devices did their job well so I would recommend them. Let me emphasize, they can't replace a full-sized oscilloscope but just for getting an idea on what's going on in a device using high-frequency pulses they do the job well.
Just a opinion from a owner of DSO203, maybe there are other options which I'm not aware of.
An owner's opinion is worth more than specs and stats I don't fully understand yet - thank you for that. What I have figured out, is that the cheap unit I linked to earlier, is cheap for a reason.
You do want to take heed of the limited input voltages of these units. I burnt one in less than a month. Went back to the "real" thing in stead. Just my 2c worth.
Hello, As I haven't used others than my two ctr scopes, I can't say much about the capability and quality of these devices, but generally speaking, the scope is the eye of the EE. Without it you are working blind, and Thai very limited. So if you can afford a pocket scope only, it will be very helpful anyway,taking care not overloading the inputs of course. Vidura.
I strongly advice against any mini/pocket/hand-held oscilloscope. From my own and other's experience they are just toys, they do not have the required triggering, precision, Sa/s, isolation between channels and so on..
Better save money for some time and buy a true oscilloscope which is much more expensive. You will find out in time there are features that are vital for your experiments.
Thanks for the input guys, you've confirmed what I suspected - that a bottom-rung DSO is mostly useless to me, unless I buy one in kit form to practice on...
Having spent a bunch of time researching oscilloscopes, about the only thing I've determined with certainty is that there is no perfect oscilloscope. Price, Bandwidth (samples/sec), Speed (mhz), Resolution (bit depth), Channels, Features (XY, FFT, Available Measurements) - The better one or two of these are the worse everything else is.
I would focus more on Features and Quality of the firmware if I had to choose the most important of these. A 4 channel scope is also really handy. Speed and Bandwidth might be worth giving up as they are more important when working with higher frequencies.
If you think the same way I do, you might like something like this: GW Instek GDS 1054
When spending this sort of money, it is important to educate yourself on what you need, spending 20G's on a scope and not using 50% of the features is pointless.
I recommend especially when starting off, purchase something you yourself is comfortable with, and think can learn without too much trouble. Everyone here will be more than willing to help with Scope best Practices, but there is a learning curve.
Cost is the biggest issue with any piece of equipment.
Stay within your budget, get what you are comfortable with and make sure that hard to find balance is met.

Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago go by instinct or reason. It has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antheus, who drives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians, and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic? If static, our hopes are in vain; if kinetic - and this we know it is for certain - then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.
