What is Reddit's opinion of Rigol DS1054Z Digital Oscilloscopes - Bandwidth: 50 MHz, Channels: 4 Serial Decode Included?

From 3.5 billion Reddit comments

Don't know much about fire alarm except how to install, but back when I was getting into electrical engineering Rigol was a reputable brand for students/hobbyists and worked great. Small enough to be "portable".

The 5k fluke is most likely their power quality meter and is amazing for power analysis. I've only been trained on it and haven't had the pleasure to really dive into it, but if your company is going to buy it and/or you plan on using it often grab it. Otherwise a nice quality digital should do you well. The more expensive ones are for higher resolution for electronics.

Get this one

Then look up the the have to get the added features. It's a serviceable scope, and I even use one at work pretty often. The probes that come with it kind of suck though.

You don't actually need that high of a sample rate, since it's just audio you're dealing with the highest you'll be scoping will be ~20kHz. But should you ever do anything else you'll want a higher rate. Here's what I would recommend: Rigol DS054Z

Edit: I bought the Tenma one for the same price and it is nowhere near as good as that Rigol. Seriously for the value, if you want to spend less than $500 that's the one to go with.

Not that they are totally worthless, but most people say a used <$100 scope is better.

The other option is save your money for something like this for $400: https://www.amazon.com/gp/product/B012938E76/

There are firmware mods that take it to 100MHz and open up all kinds of features, like serial decode.

I have this one and I'm happy with it. I have another cheaper one which is good and useful, but the Rigol has much finer control than that one.

I would suggest not getting a software 'scope, no matter what you do, because it may rely upon an audio interface, and I haven't yet seen an audio interface that has DC-coupled inputs. (You need DC-coupled if you are going to analyze signals under 10-40Hz or so, because an AC-coupled interface will not represent them correctly.)

Firmware hack ftw. 100mhz oscope for 350$. https://www.amazon.com/Rigol-DS1054Z-Digital-Oscilloscopes-Bandwidth/dp/B012938E76/ref=sr_1_3?dchild=1&amp;keywords=rigol+ds1054z&amp;qid=1597796927&amp;sr=8-3

It may be too expensive, but this is what I'd do if I was going into robotics and needed a "forever" scope: https://www.amazon.com/Rigol-DS1054Z-Digital-Oscilloscopes-Bandwidth/dp/B012938E76/ref=sr_1_3?dchild=1&amp;keywords=rigol&amp;qid=1599762141&amp;sr=8-3

And then I would watch this video:

No, don't buy a them scope until they've been through a few courses and have a better idea of the direction things are taking. Especially in a time of COVID-19 when who knows what's going to happen next. Even if this weren't the case, students recently enrolled are known to change from one major to another and suddenly, the oscilloscope is gathering dust. If, however, you're bound and determined, then $350-ish gets something decent, 4-channels, 50MHz https://www.amazon.com/Rigol-DS1054Z-Digital-Oscilloscopes-Bandwidth/dp/B012938E76/ref=zg_bs_393269011_5?_encoding=UTF8&amp;psc=1&amp;refRID=QZPWW1JWTX5SZC2RWJZK

Yeah, back in the 90s, a basic 20-40MHz scope was good enough for audio, for your tracking pulses/feedback from your CDs/DVDs, most of your digital pulse trains, whatever.

&#x200B;

Had one friend who used an old tube scope for most of his troubleshooting, but he was a next level luddite. The scope also had an external sync provision, so that kept it going far past its 1950s prime.

&#x200B;

Modern times, you can save your empty beer cans and get yourself a $400 Rigol 50MHz that should do just about anything.

&#x200B;

If you just need raw speed for digital troubleshooting, there's this thing. https://www.amazon.com/Siglent-Technologies-SDS1202X-Oscilloscope-Channels/dp/B06XZML6RD/

&#x200B;

Ultimately, the "math is hard" crowd is gonna have to find out just how many gigasamples they need in burst mode, and how much speed they need in sustained trigger more.

And lets face it, I've had newbie industrial automation engineers who just about had a stroke trying to figure that one out. lol!

Mine was $350. https://www.amazon.com/gp/product/B012938E76/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&amp;psc=1

Would something like this be usable?

Special after judicious application of riglol 'upgrades'.

Rigol DS1054Z

Hah yeah, it's a Rigol DS1054Z, about the least expensive new scope you can buy.

I've found a few pages that talk about this type of DTR-only reset circuit for the ESP8266, but it's based on the Arduino schematic.

edit: also SJ2 is a solder jumper with a cuttable trace in case I need to disable the auto-reset.

just so yall know the Rigol DS 1054Z can be hacked to be a 100MHz scope (normally 50MHz) and have extra triggers
