Yeah, I guess there is the "whole new platform" and then there is the "mid life kicker" upgrade. Now Im not talking a whole new analog front end etc. Im talking the digital & ui pieces.
Im leaning heavily towards the Siglent 1104-XE. Yes its ~$150 more, but it has a better display, deeper memory, quicker ui response times (presumably faster cpu, dual core), the FFT seems actually usable and the bode plot is sort of bonus (but a half baked wip).
But those are all things I could see easily in a mid life kicker from Rigol. But I guess you could just say, hey, that is the Rigol 2000, 4000 or 5000 series... If they did it at the same or near price point they have today, they would eat away the siglent low end business.
Alas, perhaps the MSO5000 series is the better way to go as it has way more features and capabilities and I could avoid buying a $350 signal generator.
Hmm...
