This week i had opportunity to play with Tektronix 4000 series.
I was left disappointed may be because i saw Aglinet 7000 scope before it or just the sales man couldn't sale it for me.
it has great performance ,low noise,big screen there no comparison with my rigol, but for $13k you get basic model without special triggers
You have to pay $1.5k for every type of trigger and communication decoding.
the software felt fery simple not far from rigol without any special tests like Eye test .
when i moved from my old analog scope to rigol ds1052 i felt like i got new swiss knife you could test and debug everything with it, there no such feeling when moving from $400 scope to $13k Tek
I am embedded engineer and maybe i don't see the great performance that analog engineer would see in this scope.
My suggestion is to sell this scope and buy scope from less "NAME" company but that gives more advanced features like trigerring on and decoding serial busses.
