How does Agilent do 80 GSa/s?

(1/3) > >>

IF:
Hi,

I cannot wrap mind around the new line of Agilent scopes, the 90000  X-Series. How did they manage to get 80 GSa/s of real time sampling?
Is this a similar trick with multiple AD converters, Rigol used in their scopes?

Cheers!

High end real-time scopes use both interleaving (either in time or frequency domain) and really fast ADC's with a proprietary semiconductor process (no overclocking standard AD parts at these speeds). Some of the past high-end Agilent scopes had 80 interleavers per channel, not sure about the current ones.

They use  a custom Indium Phospide front-end IC : Datasheet with cool pic of chip
The price tag on this scope is well into 6 figures - even the probes are $20K each!
I notice the various models only differ by bandwidth - I wonder if the ASIC includes a bandwidth limiter like the Rigol scope :)

Probably, in the datasheet, they say that the bandwitch is fully upgradable...
"Buy the performance
you need today
knowing you have the
headroom you need
for tomorrow with
bandwidth upgradability
to 32 GHz"

At those prices, they must be manufactured to order and there's no way our Dave will get to "Take it Aparrt!" in his garage!!! ;D
