Daniel says there is an update coming soon to improve boot time.

--- Quote from: TK on December 31, 2018, 03:56:39 am ---I think Spear600 is old compared to new CPUs running faster and with more cores and Probably the old Windows CE was a better fit.  That is why I asked about the responsiveness as it seems Linux is heavier and the same reason for it to take 1 min to boot might impact on the performance of the scope app

Linux doesn't have to be heavier. That is nonsense. Also the boot time of a Linux system is defined by the speed of the flash being used. Put a Sata SSD in an embedded Linux system and it wil start in seconds. Besides that the oscilloscope likely does a quick self test during starting.

What I meant is that PROBABLY the specific Linux distro in use is heavier than Windows CE on the SPEAR600 that the Keysight scope uses. 

I know it can be made to boot in 10 seconds like the R&S or the Micsig TO1000 scopes, probably by using some battery backed memory to keep persistent code and data in memory saved for the next boot.  I wonder if R&S scope takes longer to boot after a firmware update or the update process per se stores certain code & data in persistent memory.

But if they decided to go with the 60 seconds boot time, then there must be hardware limitations on the current SPEAR600 + flash + ASIC interface to implement specific techniques like smartphones or tablets.

The R&S are always fast. They don't use linux either.

Hydron:
R&S uses freeRTOS or something similar (it's listed in the open source acknowledgement thing). The boot time is always fast, and i don't think it saves anything between boots to do it. Definitely nice to have it that quick but I think Linux is also a reasonable choice if optimised well - boot times aren't everything.

Hydrawerk:
I still love my Agilent DSOX2002A introduced 8 years ago. Is there a successor coming?
On the other hand, Tektronix still has no successor for that MSO2000B from 2008 or so. And they still produce TDS3000 from 1998! https://uk.tek.com/oscilloscope/tds3000
OK, they changed the floppy drive for an USB port.

Aidanator7000:
it appears they launched it today.
