Yes I agree the Siglent is more modern I should have taken that as a marker, the scope is only for general purpose use and I'm only interested in 2 channels. I do have a beast of a HP1744A... a scope I don't wanna be moving too often, preferably not at all!!!! These modern 'doofers' makes it feel outdated.
The reason for the 200Mhz version is for the 3db points, I'll never measure at this frequency but OK for signal tracing say a 144Mhz signal. The reason for eying the Rigol was that there was a write up on the 100Mhz DS2102 I think the model was and it showed a 144Mhz signal way past it's dB point.... and as the prices came down my bandwidth went up.
I was reading where many a scope have been 'bricked' by attempted updates, I really just wanna buy and use it as it is knowing the only stopper is the firmware.
I would have thought Rigol would have updated their models by now, wonder if it is in the pipeline as they seem to be giving various offers on them, maybe they know it's time to.
