WG: [RASMB] AUC Upgrade

[wendel.wohlleben at basf.com]

Hallo Christine,

we had both of our XL-I upgraded in february 2006, exactly in the way you
describe it: PC, CCD, software:

The dark noise of the new CCD and new frame-grabber is somewhat better, but
the pixel size and number is identical, leading to no significant
enhancement in fringe shift accuracy.
The new software is the old software, with only 1 new feature: Data from
cell x is 'sometimes' saved as data from cell (x-1). 'Sometimes' means a
few % of all scans are missorted. The problem is aleatoric, independent of
waiting time between scans and less dramatic on one of the machines. We can
eliminate scans from the analysis, depending on bad residuals in fits, but
what if you run two very similar samples - how do you identify a missorted
scan? What I find incredible is that this bug was known with Beckman before
our placement of order, but they told us only after the upgrade !!! Since 9
months they are unable to fix it.

Now, why did I spend the money for virtually no progress? Simply because my
IT-department no longer tolerates Win95-PCs in the network. If you can
still escape ;-)  don't upgrade, wait for Tom Laue's next-generation-AUC.


Beste Grüße, Wendel

Dear all,

Is there anybody who has already upgraded an OPTIMA XL-I??

We purchased our equipment in 1997. It is still
very well functioning and was not too much used.
Now I intend replacing the PC, software, digital
camera, software,...- the complete set offered by
Beckman.

Is there anything special that I should consider?

Thank you,
Christine
