Biggest change is probably the type of material for the table you use which
needs to be proven not to affect the results. If you have wooden tables then
you are going to have a large uncertainty value. There is a bit of work needed
to prove your material choice has no effect and doesn't then ne
Any major differences here? I assume the limits are the same ... maybe small
changes on test set-up, etc ...?

You have to be a bit careful comparing the requirements around old
incandescent lamps to more modern equipment.
The glass envelope filament lamp requirements have a lot of history
attached. You couldn't, for example, pass an Edison or bayonet mains
lampholder using typical modern requirements bec

I just discovered another company that makes similar RF generators - Wind Freak

Hi there,
First, IMHO eval boards are typically end-use apparatus as they are not likely
integrated into other equipment or even into enclosures.
I wanted to chime in on this to mention that such an allowance may be found in
Article 4.3 of the EMC Directive. Although eval boards are not specific

Hi Gert,
It's not a absolute requirement for these board to be sold
as a bare PCB. It has consequences for the prices of course but
that is valid for each device, not for development boards only.
Not agree.
I hardly can imagine not development board sold without enclosure and

You are referring to FCC CFR47 Part 2.803 (c)(2)

Your philosophy is mine but for one thing:
It's not because a product cannot meet requirements as put on the market
that it should be excluded ..
It could for example be sold in an enclosure, so as to meet ESD requirements.
It's not a absolute requirement for these board to be sold
as a bare PCB

Hi experts,
Australia regulatory question:
My question is if it´s or can be allowed to operate some demo
telecommunication equipment in a customer lab before we have the regulatory
approvals for Australia ready?
If such information exists in the regulation, where can I find that information
?
