Bird Technologies 8000 Series - Manual (Page 10)

Power and
Utility
Requirements
These loads are passive devices that are self contained and
do not require any external source of power or utility to
function other than the RF input power.
Environmental
Requirements
These loads should be operated in a dust and vibration-free
environment. The ambient temperature range should re-
main between -40°C and +45°C (-40°F and +113°F) for
proper operation. Allow at least six inches of clearance
around the units to permit an unimpeded access of convec-
tion air currents for adequate heat dissipation.
Items
Furnished
Series 8000 Loads are normally equipped with a
Quick-Change “QC” connector for convenient and easy inter-
change with other AN type “QC” connectors. Model 8431 has
a Small Quick-Change “SQC” connector which is not inter-
changeable with “QC” types. Consult the Specification
Sheet, Page 3, for the connector type normally supplied with
each load.
Items Required
The only other item required is a mating connector on the
coaxial transmission line to which the load will be con-
nected.
Tools and Test
Equipment
Only a screwdriver will be necessary for changing the “QC”
connectors. None of these loads are subject to any further
disassembly. An ohmmeter or resistance bridge with an ac-
curacy of one percent or better at 50 ohms is useful for
checking the resistance value of the RF section assembly.
