of aperture. e.g. <150µm in 20mm radius
<2 x 10-3
of aperture, in 0 to 5MHz bandwidth. e.g.
<100µm in 20mm radius. Below
-40dBm it increases by
20dB/decade. Decreases with square root
of bandwidth.
e.g.<15µm above -40dBm in 100kHz
in 20mm radius. |

Near zero. May be eliminated with the use
of the beam

±3%. Worst case when beam is 6dB off
center.
