Dear Group,
I am interested in a forum for medical auditors. Any leads?
Thanks and Happy Holidays!

Yep! Aarggg!
Missed it when I wrote it.
Even the entry personnel at the search websites keep typing
photon as a key search word when the article never
mentions a photon, but continually references phonons.

Does appear to be an ongoing misprint, mistaking photon in
place of photon. Even in advanced work:
In fibre optics nonlinear effects of Stimulated Brillouin
Scattering (SBS) and Stimulated Raman Scattering (SRS)
arise due to the conversion of a high-energy photon to a
lower energy photon, where

The word used is phonon, rather than photon. A acoustic

If I recall, the video carrier is AM with the signal strength at a peak
during at the blanking and sync pulses and the audio subcarrier is FM. I
believe that is true for all VHF/UHF broadcast channels.
It seems reasonable that an FM carrier would have less deleterious effects
on the EUT, given
This isn't a standards type of question; more of a general electromagnetics
question.

different scattering mechanisms in fiber.The article mentions Stokes
photons and acoustic photons.
Anybody want to take a stab at

I have a manufacturer who is building a one-of-a-kind packaging system. It
is very large (approx. 3 by 40 meters). It will reside only at one location
in Europe (Germany) and will be used only by the manufacturer at their own
assembly plant. It will be shipped from the US in sections and
Powerful AM modulated signals between 54 and 88 MHz are seen in the real
world from television. However, the major modulation components are
(nearly) 60 Hz and 15750 Hz (vertical and horizontal scan rates), not 1
kHz.

Sam,
Bearing in mind that the conducted immunity test applies a common mode signal,
the problem that you are encountering is demodulation of the interference
signal at the input of your EUT. You need to improve the CMRR of your input
circuit such that the common mode signal is attenuated to a
Is the some case of a computer with a integrated Modem.
You have to apply the RTTE at the equipment.
How to apply the Harmonized standards is different.

This reply is from a technical point-of-view. I am not familiar with the
rules and regulations regarding technical construction files and the like,
under which you could no doubt document a deviation from the boilerplate spec.
The spec covers 0.15 - 80 MHz. The default 80% AM 1 kHz sine wave
