Thanks for the great advice. Might be getting a good discount on the 2004A and 2014A model so thinking about which one as a starter. 30mhz bandwidth doesn't seems a big difference. I don't do stuff that require high bandwidth at the moment but never know when i will need them. Started with a single channel portable scope and realised that i need more channels for my digital+analogue signal tuning/phasing.
I suppose if 4 channel is insufficient at least i still have the option of adding digital channel later to free the analogue channels up.
One thing i never heard mention much is the start up timing of the scope, some pre-production scope seems to take 12mins to boot up and was suppose to reduce to 4mins, isn't that long compare to other scopes?
