Hi Fernando,<br>
<br>
As you know, I was investigating the feasibility to use National
Instruments' PXI system for our solenoid diagnosis. After a couple
of weeks evaluation and hands-on test of the hardware, I'd like to
proceed with the procurement. But before that, I would like to have
you review the system to see whether it meets the electrical
requirements for Hall-D.<br>
Here is the list of the hardware we'd like to order:<br>
Chassis: NI PXIe-1078
<a class="moz-txt-link-freetext" href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/209253">http://sine.ni.com/nips/cds/view/p/lang/en/nid/209253</a><br>
Controller: NI PXIe-8101
<a class="moz-txt-link-freetext" href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/207527">http://sine.ni.com/nips/cds/view/p/lang/en/nid/207527</a><br>
DAQ Module: NI PXIe-4300

Terminal Block: NI TB-4300

Terminal Block: NI TB-4300B
<a class="moz-txt-link-freetext" href="http://sine.ni.com/nips/cds/view/p/lang/en/nid/208294">http://sine.ni.com/nips/cds/view/p/lang/en/nid/208294</a><br>
<br>
Thanks,<br>

Elliott,

Mark gave me a folder with specifications for a number of modules
used in controls. He is collecting additional information and into
a a single location which will be easily accessible in the future.
This will also include all the cables used under controls.
<br>
<br>
I reviewed the specs on these modules with regards to EMC, both
conducted and radiated noise. Unfortunately, none of these modules
meets the requirements for Hall D. This is a serious issue and
needs to be properly addressed due to the sensitivity of the
detector readout electronics.
<br>
<br>
Best regards,
<br>
Fernando

Hi all,
<br>
<br>
Please submit to me all the specs related to electrical and
electronics and to all the systems that you are procuring or
have already procured. I am particularly interested in the EMI
specs covering radiated and conductive noise. These include all
the the AB controls, solenoid controls, supplies, etc. Please
also include the cable specs.
<br>
<br>
I need to review and approve everything related to electrical
and electronics and please include me on any approvals,
specs/procurements.
<br>
<br>
Thanks for your help,
<br>
Fernando
<br>
