new killer scope in town - a true game changer from R&S - RTB2002 & RTB2004

I've been with R&S for over 15 years and it's always been that way: even service manuals don't necessarily have detailed, component level schematics (the RTB2000 service manual does not - I have it in front of me).

Oh, we know -- I spent part of the day yesterday meeting with our oscilloscope product management team in Munich : )
But frankly, there's a lot more to a scope than the number of ADC bits.
(Munich HQ was still open and operating despite record snowfall in Munich last wekeend :))
Robaroni:
I'll tell you what, I just bought the Rigol 12 bit DHO924s as a back up for eight hundred bucks. It's packed with everything down to bode plots and is extremely well made. I can see things in the waveforms I can't see on my RTB. Okay so it doesn't have a 10" display but I love the form factor and it's a ball to play with. I even tried decoding and the probes don't look any worse then the RTB's which two have died in the five years I've owned it, I've had Tek scopes for years without losing probe signals or functions. Now the horizontal coarse/fine died and I can't even buy a board for it, if in fact it is the board and not some FPGA on the main board. Unfortunately I can't find out because your tech dept. doesn't even have basic schematics that trouble shoot down to board level. It's always been that way? Maybe you shouldn't have told me that, I think end users should have the right to repair with schematics and access to parts, it's not a good omen that your tech dept. doesn't even have schematics.
You have the schematic? Great, so it's not the switch on the horizontal rotary encoder, what does that switch feed? Is it on the FRONTCONTROLLER FC-2A40 (Part #: 5810.2111.40) board? Maybe you can tell me what pin so I can check continuity. Thanks!
So they referred me to your service dept. and it might as well have been a robot, I get it you want me to send my scope in for repair, what's that going to cost? I lost the connection and she never called back or emailed me with costs. I get it again, we're small potatoes.
They worked in a snow storm because they know they're in trouble and have to find solutions, they got upstaged again by China. Maybe they should invite me to their board meeting, I'll be happy to tell them how the bear went through the buckwheat.
So tell me why I shouldn't get a bigger Rigol for my next scope? That's rhetorical..... are you sure you want to have this conversation?

Maybe they don't even exist. :-X ;D
Robaroni:
The 924 has a lower noise floor, check Dave's video.
Look, this is the future, chip designers make heroes out of everyone, we can expect better and better quality instruments.
goaty:
Can we get the RTB2k service manual please ? I tried unsuccessfully logging into gloris.
I can send serial number of device with foto if that´s needed.
Thanks, Thomas
