I've seen the new 100MHz Keysight scope, it's a nice looking but if kit. Same chipset as the 3000 apparently. Does have serial decoders, but obviously limited to 2 channels, so can't work with with 3 line serial busses.
2GSPS is nice, price good, on a par with 4 channel 50Hz Rigol. Rumour has it only 50ppm but this may change.
Overall I'd be really pleased to win one. Having said that, my current 4 channel 100Mhz Micsig works well, much deeper memory than Keysight.
The real win for Keysight is the speedy interface and good sample rate for the price, good for glitch spotting.
