Influence of Stirrer Vibration During Stepwise Operation of a Reverberation Chamber

Reverberation chambers (RCs) are proposed as repeatable test environments. Often, the mode stirrers inside a RC are operated stepwise, whereby the essential measurements are performed under quasi-static conditions. However, mechanical mode stirrers usually vibrate when arriving on a new position. The influence of this mechanical vibration on the repeatability is analyzed in this paper and the results open up opportunities for future enhancement of mode stirrers movement.
