#93: RS232 and SPI bus waveforms, bus decodes and RF activity on the Moteino using Tek MDO4000

Just having a little more fun on the bench with the Moteino (see previous video on this Arduino close with RFM12B wireless transceiver), and the Tektronix MDO4000 Mixed Domain Oscilloscope. Here, we view the analog waveforms for two different low-speed serial busses (RS-232 and SPI), decode those busses, and look at the RF spectrum characteristics, and FSK modulation characteristics vs. time - all using a single capture on the scope.

OMG, the best SCOPE PORN I've seen in a while. Thanks for another great video. I wish i had that scope for debugging and repairs.

I agree tek should give you the latest and greatest. I've not seen the use for so many channels and functions in use, so clearly explained, with practical uses before. Come on tek, Agilent, and all, send this guy some crazy scopes so we can see them actually put to use and see what they are good for!

1 second to get me drooling all over my t-shirt. Your only hope to beat this record is to achieve some sort of Pavlov-effect.

hey awesome video, gives u the thrill to study these things..

[jfernandmy]

My goodness! Such a beautiful scope! Im in love with it?

Great demo of that 30k $ scope:) Tek realy should give you one for keeps, they gave 3 of them at E14 roadtest for a lot less practical and interesting reviews...
Anyway:) here is a idea for beginners videos series: Evaluation of inductor Q factor using osciloscope nad function gen

Great video, as always! That is a bad-ass scope you've got there. I'll have to pick one up the next time I have $20k burning a hole in my pocket. :(

*drool* that is one shexy scope.. what do you do that you have a $30k dso (and is that at home too??)

Hi,
Great video, I have one question is there a software that can decode capture from the scope, as I don’t have serial decode function in my scope?
Thanks

MDO4104-6 50 kHz - 6 GHz $29, 200
Ouch! Looks amazing, though.

Okay, let me add some corrections here...On the spectrum analyzer what you are calling a signal is just noise and the two peaks shifted a million hertz or so is the signal (wiki Frequency Shift Key). The yellow bar is still integrating over several 1's and 0's so you're seeing the sum of those on the scope.
