Is An Oscilloscope Practical

OK, Roger all that.

I'd be surprised if you don't really, really enjoy using the 1054Z.

Better start reading up on JDS vs FY waveform generators.

This will be somewhat like the Rigol vs Siglent discussions.  There are some other very long threads on the various FY and JDS generator versions.  For somewhere around or less than $100 one of these is likely to be your most economical solution, but I'm betting you will want a waveform generator shortly after the scope arrives.  The Siglent and Rigol waveform generators are nicer than FY/JDS but I think you can probably save some $ and be happy with the FY or JDS.  On the other hand if you have been trained in the DuPont/Fluke school of buy once cry once then you might want a Siglent waveform generator - they are an excellent value.  And if you don't already have one pretty soon you will have to search the threads for a variable power supply.  Unlike entry level scopes where the battle has largely been settled in the EEV forums, power supply choices are pretty large; many makes and models to choose from.  :)  Enjoy the journey.   :-+

Yes, you are correct in stating I have many types of electrical meters ............… and, while I'm not trying to boast, I've always purchased quality meters such as Fluke, Simpson, Biddle, etc. One reason for this was because DuPont always taught it was best to use and trust only in quality instruments and the other reason is sadly my inclination to feel I always need the best ……………. or at least better than the everyday "norm". This does come at an increased cost for me, but my meters/equipment choices have always served me well.

And you are also correct in stating that I am familiar with Ohm's law, print reading and such. Years ago, I completed a 2 year study in Industrial Electricity and for a while was an electrician with my employer (DuPont). My last 20 years with my employer was actually spent in the Technical organization as a resource for the plant's testing lab. In this position, I not only ensured the instrumentation was on aim, I was also a resource for the electrical shop which maintained the 24 hour support for equipment failures or off-aim conditions. I also worked closely with plant electrical engineers on equipment upgrades and was basically a "wrench" when it was time to tear out the old components and install the new. Therefore, this task, along with my everyday activities gave me ample experience troubleshooting, reading prints, etc. I'm far from an electronics engineer or advanced electronics student, but I do possess strong electrical skills. So yes, I'm familiar with discrete components, but nowhere near being able to design electronic circuitry.

Anyway, I hope that helps clarify some things for you and possibly others. You did hit the nail on the head when you stated:  "...……. you don't want to invest in a scope unless it gets a reasonable amount of use, which is understandable.

Thanks so much!

A quick look on eBay shows several used 1054z scopes ranging from mid $200,'s to $325. This is an Improvement from 6-8 months ago where it would be hard to find one used for sale. Buying a new 1054 then selling it a year later is likely to net you 75% of the purchase price and a quick sale. That's a pretty safe market for testing the waters.
exe:
I have dedicated power supplies, an oscilloscope, a wavegen, a bunch of dmms, a logic analyzer, but most of the time I use analog discovery 2. It's not a high-performance device, but for most purposes it's sufficient. It also save bench real estate and always at hand (read makes me more productive).

Disclaimer: I mostly work with frequencies below 10MHz, often below 1MHz.
Fungus:
Yep, the Analog Discovery 2 is a great little learning device.

Electro Fan:
+1 for Analog Discovery 2
It is a great learning device with a lot of functions

Good Summary of the features/functions, specs, and some user reviews:

By the time you add some accessories (probes, adapters, etc) the price (unless you are a student) is similar to Rigol and Siglent entry scopes.  In return for giving up some bandwidth and sampling you get a lot of tools in one compact device.  The other tradeoff is you get a PC/Mac interface rather than a knob/button interface.

Different horses for different courses but if these tradeoffs trip your trigger it is a wonderfully feature rich learning tool.  If the budget permits a case could possibly be made for an AD2 plus a scope.
