Looking for a copy of RTCA/DO-160. Original release date 28 February 1975.
Doesn¹t show on RTCA website as an available document. DO-160A wasn¹t
released until 1980, and RTCA/DO-138, the predecessor to RTCA/DO-160, was
released in 1968.
Would like to have a copy of this ³missing link.²
Thank
The picture of the AT-60 shows no heatsinking. The AT-58 has a large
heatsink. The description of the AT-75 doesn't have a picture, so there is
no way to establish similarity.
Considering applying half-rated power to an attenuator or load of known
specification, measuring temperature rise on
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
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
Perhaps. To help isolation It has several sections. Only the output end has
lower power parts

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.

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.
