I finally did it, pulled the trigger on a Rigol DS1104Z-S Plus 100 MHz Digital Oscilloscope!   Boy oh boy, this thing has practically infinite capabilities!  It's not only a 4-trace 'scope, it's also a two channel signal generator with arbitrary waveform generation capability!  If that's not enough, it's also a 16 channel digital logic analyzer as well!

Still trying to learn my way around it, sure has more features than my previous bench 'scope!  I still have to get the 16-channel logic analyzer cable to complete the package, that's coming soon.

We started buying Rigols for work a few years ago. Prices, especially at the end of the year model changes, can be pretty incredible. I picked up a 100MHZ straight digital scope, not mixed signal, with function generator a few years ago. They offer a Windows app for them as well for integrating data to spreadsheets or further analysis.

Nice!  Those Rigols are pretty sweet from what I’ve read about them.  

I picked up a mid to late 90s 500MHz Tek with the FFT/Math package for a song about a year ago. It had the CRT and color shutter replaced by an aftermarket LCD package already. I paid less for the whole scope than what the LCD kit costs. And it had already been recapped!

I thought about the 200mhz model, but I don't really do anything that approaches 100mhz that I need to 'scope.  I have to say, compared to my previous dual-trace ATTEN 'scope, this one has rampant feature runaway!

20 years ago you would have paid twice as much for just the scope, about that for a good waveform generator, and twice that for the logic analyzer.

It looks like an all-around good deal.

Yep, I've wanted a 4-channel scope for years, but the availability of the logic analyzer and function generator included finally pushed me over the edge.  I suspect I'll have difficulty using all the features.  One of the neat things I spotted for this one was serial data decoding, that will come in very useful for some projects I'm doing.

If they've added a flux capacitor, that's the one last feature and I'm in the 'can no longer resist' category!

It's on the back, not visible in this picture.

Please educate us on the applications of your new oscilloscope to O-gauge train equipment.

Uhh... I don't think I have time to bring you up to an electrical engineering degree.   I design electronics for model train applications.


Back at my old job we had a sweet Tektronix mixed signal scope, that I would sneak some home electronics projects in at lunch and test, but new job and no more scope. Been casually looking around for a scope for home electronics projects, especially focused on home-brew electronics projects to hook up to my JMRI / CMRI conventional 3-rail layout. Keep us informed on the uses of your new toy.
