Received Signal Strength Guide
The following tables are offered to assist you in gauging when your terminal alignment is
optimal. This information is to be used ONLY as a guide, as daily conditions at your
installation site can affect the received power levels for your particular link. Still, the
information from this table can prove helpful when aligning your SONAbeam link.
155-E:
‘Typical’ Clear-Air Receive Signal Strength*
SONAbeam 155-E Series Terminals @ Laser Pwr Index = 14
Range (meters) STC display (µwatts) Voltmeter
