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 mode-tuning.

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 animals? Which ones are used for which type of RF immunity test?
