Same Rigol Oscilloscope that we have is on sale at Microcenter

If anyone has been looking for an oscilloscope for home, the same 4 channel Rigol oscilloscope we have is $350 on sale at Microcenter, which is $50 off the normal price.


Yes I think they dropped the price all over. Amazon also has it for $349. I wonder for a new model is coming out. Still an excellent oscilloscope. I can help you “improve” it. :stuck_out_tongue_winking_eye:


I got a Siglent 1202x-e.

It’s $379, but 200Mhz – BUT only two channels. although the trigger channel will do clock signals, so SPI is still doable.

I’m much happier with this scope, but I have different needs than a lot of folks. It’s the first DSO I’ve found usable for my analog low noise work. The noise floor is way lower than the rigol, and sampling rate, segmented memory, and a math co-processsor really make a difference. It seems like most hackerspace folks prefer a 4 channel scope these days, but if you need to catch errant transients in the nanosecond range, the new Siglents are the only ones under $1k capable. Since I work with crazy reactive circuitry, EMF and EMI will be making plenty of signals that can’t be triggered or analysed properly at lower bandwidth.

In hobby land, it’s also way better for radio / ham stuff, as it has features that make AM and FM and complex modulation much more visible in an analog scope type way (“digital phospher”). Good choice for audio enthusiasts too just for the lower noise floor and higher wfps. But again, 2 channels.

Honestly, it works a lot like my tek stuff. People who are used to rigol dislike the UI, but it’s more like a tek – more knobs less menus. I’ve been able to do 100Mhz noise work with ferite bead circuits & complex impedance stuff. Just a few years ago I could only do that with my tek analog scope or I would have to shell out $1000+. I’m really impressed, and even the hacked rigol could not do this.

As far as scopes go, it’s important to consider what you’re getting per channel and the speed of aquisition. The Rigol’s compromise (and siglent does the same with entry 4 channel), is that the scope has to split bandwidth and aquisition between all the channels. On a 100Mhz “hacked” scope, If you have 4 channels going, it’s suddenly a 50Mhz scope with 3,000 wfps on each channel.

Anyway, if anyone wants to check it out, I’m happy to show.

That said, if you’re getting a first scope for arduino and arm digital signals, etc, the rigol is a great choice. Plus, everyone has one of those rigols, so community support is good.


I kinda feel like calling it the old-timer’s choice, as it feels familiar coming from tek & HP land.

Math co-processor is sweet. I did dv/dt on a signal the other day without skipping a beat or having to export it to the computer for analysis.

Ha, this reminds me off Ford/Chevy discussions over beers. :grinning:
The problem is that everyone is “right”. It really depends on what you are going to use it for.
I think the Rigol has a huge following and there is lots of support.
I bought the Rigol for home myself, just so I would have the same one from the Hive. (I even got an ebay Rigol function generator like the Hive).

I love me an old analog scope. I have two TEK’s that are awesome. One even has some storage (4K points)! It probably cost $10,000 in 1985.
Kind of like old muscle cars. We have fond memories, but a new sports car would run circles around it.

The important thing is to keep it fun. I’m thinking of doing another introduction to the oscilloscope class, maybe after one of the Tuesday meetings if there is some interest.

Actually, I was thinking about doing this project:

We could build a few at Hive as a class. Could break it into the theory & design, and then do smt double sided assembly another day.

Whata ya think?
