someone (don't recall who) has a small reverb chamber with some fluorescent
lamps that come on and go

Don¹t understand the post below. The original post starting this thread only
asked for definitions. My initial response cited the fact that MIL-STD-461
only allows mode-tuned, not mode-stirred testing. A later post seemed to
imply that the higher the frequency, the more paddle positions would be

All,
Over the years, I've come across pictures of test chambers with
descriptions such as mode-stirred, mode-turned, and reverberation. They
seem to look similar, with metal walls and rotating metal paddles.
Do these names reference the same basic design, or are they different

One can mode-stir or mode-tune a reverb chamber. Mode-stirring is continuous
the paddle never ceases movement and mode tuning utilizes a stepping
movement, holding each mode for a specific time period to allow assessment
of susceptibility.
Can¹t speak for others, but MIL-STD-461 only allows

Not obvious to me that the original question was asking for a
recommendation; only a definition.
That being said, the below seems to be somewhat at odds with MIL-STD-461
paddle position requirements. Table VIII in that standard requires the
