Also got more noise, see picture with only 1 channel, and then enable channel 2,
the difference is clear, on 1 nS the sample rate is to low for two channels.
The performance is worse on 1 nS then on 2 nS.

There is no 200 MHz bandwidth limit available on the new firmware, correct.? Maybe that would eliminate this noise when the higher badwidth is not needed.

I'm still using cyberbet's fimware at 300 Mhz but with 200 MHz bandwidth limit available. No CAN but I have no use for it right now. Still undecided if I should update to the newest firmware....

IMO the improvements in the latest FW are way more valuable than the ~50MHz of extra BW you may be getting with that old FW version.

Strongly agree.
I just want to add, it is not only the BW, and noise, a base time of 1ns is quite useful.

i dont agree, the 1 nSec, has only 2 samples ( one channel) or 1 samples ( two channel)
so be carefull what you measure... can be not so usefool

2 samples per div (1 channel) or 1 sample per div (2 channels).

Well, IMO, a 1ns time base with 2 samples per div and a blind time of 99.94% is just moderately useful.
