David,
thanks for the great information! This is the theory we're subscribing to. The
arc mechanism takes place at the negative electrode. I just tested a mercury
wetted coaxial relay, from 0 to 500 volts and it exhibits a 10 volt drop
across the arc. It is not polarity sensitive, which
It depends on which ETS/EN standard is applicable for the Radio some of them
have the antenna parameters specified as part of the spectrum parameters.

Amund,
Another antenna may alter the Radio and EMC behaviour of your radio
transmitter. So you must check if the complete system with the other antenna
is still compliant with the applicable harmonised EMC and radio standards.

Dear Dave,
You are working on a difficult issue.
Every HV relay will breakdown before the contacts touch. The reason is
as follows:
When the contacts come closer the surface field strength
Increases. The field strength will increase so much, such
that the field emission current reaches
Hi,
We have speaker products that can be connected to PC or
walkman/Hi-Fi/DVD/CD/VCD player.
The speaker is just an amplifier which take analog input via stereo jack..
It may be a multichannel speaker system.
For this speaker products, what is the EN standard to comply?
EN55022/24 or
I'm designing some ESD test equipment for in-house use and need some
suggestions on relays. I am experimenting with a 5 kV COTO vacuum relay and
notice that I get some runt pulses. It appears that the contacts arc before
they touch and then the arc extinguishes after 50 ns and then reignites.
Safety Engineer:
As a Safety Engineer at National Instruments (NI) in Austin, Texas, you will
be responsible for ensuring our products are designed and tested to verify
compliance with foreign and domestic safety requirements. This is an entry
level product safety testing and engineering
Could anyone provide lessons learned/commentary on the use of any recent
model McIntosh amplifiers for either MIL-STD-461 CS101 or DO-160 Section 18
testing? I currently am using a legacy Solar 6552-1A but am looking for an
amplifier with higher power output capabilities.
Thanks in advance,

David,
Thank you for the additional clarification. It took something like this to
get the production of light aircraft back into gear in the US several years
ago. A 30 year old plane would be flown into a mountain due to pilot error
and the heirs of the pilot would sue the manufacturer because
