Based on my experiences with HDMI I've found the high speed TMDS interface used
on DVI (and HDMI) can be very difficult to control indeed.
Cable backshell shielding is critical to low radiated emissions. 360º
continuous shielding between cable shield and connector shell is required.
Finding a g
Here is a specification sheet for the Empire Devices AT-60. I can't state
whether it would have similar ratings to the AT-58, but it may provide some
guidance.

I may have posed my question unclearly.
What is the power handling capability of an Empire Devices AT-58 6 dB
attenuator, properly inserted in a circuit?
The balance of the discussion was just there to pique any old memories.

Perhaps. To help isolation It has several sections. Only the output end has
lower power parts

While the schematic may be a pi or T network, internally it may be a
series of pi or T networks, each section of which dissipates a given
amount of wattage. This means the input pi/T might attenuate say only a
few tenths of a dB, while the last pi/T also dissipates about the same
amount of powe
Make that "older-timers."
Just purchased an Empire Devices AT-58 6 dB attenuator. It's big - looks
like it ought to handle 100 Watts, but there is no indication of the power
handling capability.
Input and output are marked, and only the input side is supposed to face the
high power source, so the
Hi Nic:
"Opposite polarity" is a term I first came across in UL standards.
As you have, I understood "polarity" applied to D.C.
UL applied the term to A.C., meaning the opposite (or return)
pole of the supply.
Here's a definition of "polarity" from the net:
polarity (p??'lær?t?)

Line to neutral for mains-connected Class I equipment. Line to line for
3-phase equipment.
There are additional requirments for Class II equipment.
In Texas, opposite polarity represents the different sections serving beer
and wine.

Edition 3 of IEC 61010-1 added the following line to Section 9.6.1;
"A minimum of BASIC INSULATION is required between MAINS-connected parts of
opposite polarity
on the supply side of the overcurrent protection device."
Does anyone know what "opposite polarity" is supposed to mean in this contex
