I work (job, not hobby) with 2.5kpts on a tek and 48k on a picoscope. That's just fine.
Since the pico decode from acquisition memory (i.e. current buffer or all buffer on host computer) i don't have the need to acquire at a slow timebase then zoom in and hope it will be decoded and no data was lost during sampling. Zoom out, reach for new packet, zoom in, repeat (as i have to do on the rigol at home)
Less amount but segmented memory and proper decoding is what i need. Can decoding is a must. A proper user interface is also welcome.
