Haha yeah true but you would have thought they could have gone to 6M with no issues on a 6000 count meter. Now it’s in my garage to test my mains and car battery
I have a 101, cheapish, CAT III 600V, and does MΩI’m just mad at it cause it made me change out good components
Very true and I do trust my Fluke, I know it's built with safety factor and not only will be protect me but it will survive and keep ticking.This encapsulates what you are paying for, and it's not just labeling, it's trustworthy:

There are some regulations, but the problem is 100% on enforcement. Five, six years ago it was already difficult to track with so many models and re-branded meters, and about two years ago the problem was only compounded by so many newcomers. Add to that the sheer amount of direct offers from China's outlets and you have something very difficult to enforce.What I don't understand is that there is no law to prohibit manufacturers from making false claims of CATIII/CATIV and NEMA ratings. It just shouldn't be allowed!
My little toy just saved the day... last week I had a customer call me with an emergency who's located in the region of Sonora (which is about a 2 hr flight from where I live) and as an afterthought, I packed the little midget along with my MM, device programmer, soldering station, and some other standard tools and spare parts.While you guys have been bickering and measuring scopes that sell for under five hundred bucks, I ordered an amazing $20 dlls ultra-miniature digital scope boasting an impressive (at least on paper) 1 MHz bandwidth and a beautiful 1.75" (diagonal) screen ...
Anyway, the thing's so small that it fits right in your pocket, and it's perfect for quick on-the-field machinery diagnostics such as encoder readings and RS232/485 monitoring ... it's a rather pretty (and useful) toy, and I don't care who hears me saying it ...
For example: ChA - Transmitter clock, ChB - Transmitter data, ChC - Receiver clock, ChD - Receiver data
... Kinda see if they all "match" and debug problems?
Despite that there are even more differences, the SDS1202X-E has real 500uV/div sensitivity, 1 Mpts FFT and free decoding capability.I don't remember the last time I read a whole thread (not just the first page and last two pages)!
Since I am not travelling to work anymore, I got a bit more spare cash and decided to get me an oscilloscope.
I did a lot of research and found, independently, that the two most popular serious-entry-level scopes are the sds1202x-e and ds1054z. While trying to find a comparison of these, I saw this thread and got hooked.
Of course, the modern problem of choice kicks in
If a person has choice - they are confused, frustrated, hesitant and scared to make the wrong choice
Even though we seem to have two options that are somewhat above the rest, now it's a bit of a ping pong on which to choose.
But I also think there's a real consideration here, as these two aren't 1:1 comparable. One of them has 4 channels, the other has more bandwidth...
Another recent model to throw into the mix is the 100 MHz 4ch SDS1104X-E or SDS1204X-E which sounds like 4ch big brothers to SDS1202X-E but are even more advanced with Bode plot capability (with external signal stimulus) and WiFi, AWG and 16ch MSO options, all of which make them a DSO you can grow into as skill grows or as need arises.I am mostly interested in studying waves. The math involved is so cool... I don't like digital system as much.
Therefore, my kinda thinking is that with the Siglent sds1202x-e, I'll be able to see phenomena in waves in more detail.
Do I understand correctly that the main profit of having more channels is that one can track a bigger system of waves?
For example: ChA - Transmitter clock, ChB - Transmitter data, ChC - Receiver clock, ChD - Receiver data

This sounds more like a digital systems problem that I might not be interested in, for now...
You'll better hurry... a good shed is never complete without a decent scope in it...Glad you found this post interesting, it never fails to amaze me how many times this post has been resurrected. I hate to report I still don't have one yet. Its far on the back burner behind three remodels. A beer brewing fridge and probably a shed.
Enjoy yours though and its great to see some one positively charged about electronics. LoL
I'm living vicariously for now on your excitement.
That's what I did, got a nice analog scope, and a nice early DSO. The only thing's I don't like about them, the DSO weigh's a ton, and the lack of parts, but I guess that's the same for new ones too, but at least with the old ones you can find the schematic's.If you are starting out- you can buy a good used top brand analog scope like Tektronix on Ebay, use it for a year and re-sell it for what you paid.
A Tektronix 2236 can be found for $300.00
Nice! My part of the CV check is buying a SDS1202X-E so I don't have to haul my other scopes around the house for projectsI'm getting the SDS1104X-E very very soon. That's going to rock. I'll still keep my analog scope, but I should release my DSO, back to ebay from where it came.
Consider the SDS2202X-E and although it has the same BW it's got a few features the 1202X-E hasn't. Unfortunately it's a chunk dearer too.Nice! My part of the CV check is buying a SDS1202X-E so I don't have to haul my other scopes around the house for projects
I've got access to much higher end stuff. This scope is a outdoor work shed resident and is in my CV check budget negotiated with tough a tough cookie called the wife.Consider the SDS2202X-E and although it has the same BW it's got a few features the 1202X-E hasn't.
