Peter,
I have used the EMTest CWS500 system, as well as the Teseq (schaffner) NSG2070
system. They each have their limitations, specifically, niether can be
controlled by an external computer, other than initiating a test or
calibration. In other words, an external computer can't adjust the output
level of the signal generator, read the input level during a calibration, or
read the induced current level during a test. You pretty much are stuck with
the canned internal routines to run calibrations and tests.
Actually, it may be possible to control the NSG2070 by an external computer,
but Teseq will not release the GPIB commands to do so. Believe me, I tried!
All I was able to get were the commands to initiate the internal routines. I
suggest that if you buy an all-in-one system, check to make sure an external
computer can *completely* control the system. I would seriously look at the AR
product, it appears to be modular and each component can be used independently.

Where I presently work, we have the CWS500 but only use the internal
amplifier. We use an external signal generator and spectrum analyzer instead
of the built-in components.
Hope this helps.

Hello group,
I am looking to purchase a single box solution for the above standard
(Conducted immunity) to do some ITE products. Can someone recommend me a
manufacturer? You can do that off line if you do not wish to copy the group.
thanks
Peter
