It is correct that the DC282 from Agilent/Acqiris is going to be used for the LCLS AMOS and possibly also for the LUSI experiments. Also XTOD has purchased them for the FEE (implemented at LLNL for LCLS)
At present we have it running under Linux but we are porting RTEMS to the cPCI Coherent Technology INTEL processor followed by the RTEMS driver for the Acquiris. We will be running EPICS as on other LCLS contols & DAQ hardware,
My guess it will take another 2-3 months for that since we don't need it any earlier, as usual priorities...
We have two of those waveform samplers at SLAC but will need to order more.

Amedeo (see cc above) will know the details.

Gunther

At LCLS, Dr. Gunther Haller is using an agilent Acqiris scope.
At least this is what I read in one of his presentations.
http://www-glast.slac.stanford.edu/Elec_DAQ/lcls/Reviews/Haller-Lehman-LCLS-Controls-7-07-v5.ppt
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.
