Hello Geroge
We have tested several products with different PCs.Our result is that the
HP Vectra is the best up to know. Dell has some good product too.

Subject: PC's & Class B..
Hello All,
I will be buying a new PC for EMI/EMC testing. Can anyone suggest a mfgr. /
model that is (truely) Class B compliant?
Thanks,
George

George,
We do Class B rarely, but last April we used a Dell XPS-T450 model CPU with
Dell
828FI monitor to retest a GPIB interface card for Class B CISPR/FCC at 10
meters. The highest radiated emission recorded was 2.6 dB below the limit
at
214.8 MHz vertical mode. The test configuration included an Panasonic P630B
parallel printer, keyboard, mouse, and a serial modem. Conducted margin was
4.9
dB at 183 kHz.
We have the local contract lab run Class B FCC/DOC since we haven't
attempted
yet to seek a NVLAP on our own 10 meter site; more than 99% of our testing
is
Class A.
If you buy a Dell, don't try to pick up a used one more than a few months
old.
Dell had a radiated emission problem with one of their power supplies about
a
year ago.

George,
I think you are going to hear from many folks this morning. The short
course here is to buy it with a stipulation that says if it doesn't pass you
going to bring it back. Many big name vendors have systems that have
problems by the time you see them. Could be because of the shipping and
vibration of the enclosure cover, or the peripherals you are using with it
not being compatible etc, but you might have to go through a few to find
what you need.
I have tried this with HP, IBM, and Compaq and I am very sure that they
run the tests and run them appropriately, but I still have run into
problems, but I would start there.
Another recommendation is that if you don't have the test facilities at
your place you may want to see if your test vendor will store the unit for
you and buy a second system. Shipping this things around is very hard from
and EMC performance perspective.
Gary

George,
I have had great results with a Gateway tower. Mine is only a 200MHz CPU but
the chassis is built like a bomb shelter. Even the EMC labs I deal with were
suitably impressed.

George, I just bought a HP Vectra. The PC is OK, but it's monitor is
marginal.
I understand the bigger the monitor the better the shielding, as they can
charge
more for the monitor.

In my test lab days it seemed the Compaq and Dell PC cases were the tightest
built.

George,
I have had excellent luck with Dell Computers, especially their Dimension
line.

Hi George
I will be testing a DELL dimension within the next two dayes. It looks very
good with may very good EMC solutions, but in My TEM celle the CD-ROM dirve
is critical. If I forget to send you the results of my test on Friday
please contact me.
Best regards,
