IMPORTANT
•
Connections to the transmit and receive IF ports should be made using a good quality
coaxial cable. For example, RG58 or RG59 for BNC IF connectors and LMR200,
LMR240 or equivilant for the L-band SMA IF ports.
•
All 'D' type connectors attached to the rear panel must have back-shells that provide
continuous metallic shielding. Cable with a continuous outer shield (either foil or braid, or
both) must be used, and the shield must be bonded to the back-shell.
•
The equipment must be operated with its cover on at all times. If it becomes necessary to
remove the cover, the user should ensure that the cover is correctly re-fitted before
normal operation commences.
