Does anyone know how to do this? I have a bunch of ideas written
down at the <a
href="https://www.hamwan.org/t/tiki-index.php?page=Radio+Analysis&structure=HamWAN">Radio
Analysis</a> page, but honestly it feels like stabs in the dark.
I don't have any true noise generators with adjustable bandwidth
(donate! :)), so my simulated wideband interference signal consists
of a bunch of peaks instead (FM'ing a carrier with a sine wave).
Any tips or help appreciated.<br>
<br>
Also seeking 1W+ 20dB+ 6GHz+ attenuators, and splitters/combiners
(with good isolation) that can work @ 6GHz+. I'd like to simulate a
full cell site (3 PtMP sectors + some PtP links) within a totally
confined coaxial system, and inject arbitrary noise into it. Given
the cost of these microwave attenuators + splitters, it might be
easier to set it up with real antennas instead. But that has
problems of environmental noise and multipath / echoes.<br>

Linked from the Radio Analysis page is the <a
href="https://www.hamwan.org/t/tiki-index.php?page=RouterBoard+Metal+5SHPn&structure=HamWAN">RouterBoard
Metal 5SHPn</a> page. It has the result of 1 performance test so
far, dealing with amplifier clipping leading to increased sideband
energy. This is of great importance in designing sectorized
systems. When these unexpected sideband emissions leak into
adjacent antennas, you can shoot yourself in the foot. So I'm
trying to characterize the tolerance of the radios to nearby or
in-band interference. Doing this in TDMA/OFDM space is not trivial.<br>
