Are there any mandatory regulatory compliance requirements for ITE products
sold in India? Safety or EMC? What about WLAN?
I have heard about S-Mark for Safety, but I am not sure if it is must to have.
It is mostly done under STQC scheme, established by Indian goverment, but
their website is
Thanks!
I greatly appreciate all the helpful hints I got regarding field uniformity.
Thanks to your suggestions and I now have a 3 meter chamber that meets the
10V/m field uniformity requirement.
Thanks again!

Understand both directives have different level limit. In terms of testing
methods, are they identical or different? Your advice is appreciated.
Thanks,

Greetings All,
Thank-you to all who have responded to my query on, TLM: Laplace and discrete
difference equations.
There have been some recommended books that I'll be getting to further my
understanding of TLM.
The following are the books that I have read so far regarding modeling. They
include
Hi Dave:
The voltage drop fluctuations due to load fluctuations
is a function of the source impedance of the supply.
This applies to both the secondary side of the
distribution transformer as well as the supply to the
primary side of the distribution transformer.

Set the time step size small enough to represent your
intended bandwidth of interest.
There is a book that contains the simulation equations
[theoretically derived and empirically modified] for 22 and
24 gauge wires, two sets of wires used in telco
transmission, good to 1% accuracy over the

Howdy All,
I'm trying to get an idea of what sort of voltage fluctuations(AKA

secondary.
I'm not sure what the HV feed is (7200, 4000, or 480VAC). The EUT

We are in the process of designing a number of items of special-to-type test

I would like to understand what is considered normal practice throughout North
