At LCLS, Dr. Gunther Haller is using an agilent Acqiris scope.
At least this is what I read in one of his presentations.

Not sure about the state of the development of epics on the
scope/digitizer.

In his presentation I read:
Up to 8 GHz waveform sampling, 1 usec record or 1-GHz, 500-usec window
At 120 Hz -> 100 Mbytes/sec
High performance to move or process data 
Waveform is time-stamped via EVR
Respective beam-quality data is attached to each waveform
Agilent Acqiris 8-GHz, 10-Bit DC282 cPCI Digitizer Module

That's exactly what I want ! ;-)

Clearly not a scope in the league I am looking for.
(Bandwidth, sampling rate, memory size, etc. are out of range)
That can also explain why it is so cheap in comparison to the ones I am
looking at. I like Cosylab epics support nevertheless.
