2.2.3 RF Connections 
Care must be taken when attaching the RF connections to the PA, to prevent costly damage to 
the equipment. 
 
When fastening the connections, do not cross thread them.  The “N”-type connectors used 
require 90 N-cm or 8 in-lb of torque for proper connection.  
 
2.3 SCPA Operation 
2.3.1 Powering the SCPA 
The PA should be powered by a regulated DC power supply. The PA has a built in reverse 
polarity protection circuit. The PA should be supplied with -48VDC and shall consume less than 
300W in a normal operational state. See PA’s Technical Specification for DC connector pin 
assignment. 
 
2.3.2 Tune Up Procedure 
 
•  Attach RF power meter and load to RF output port of PA 
 
•  Attach RF source to the input port of PA 
 
Before applying DC power to the PA be sure it’s output is connected to the appropriate load and the  
input power level is set to minimum in order to prevent RF overdrive. 
 
 
•  Apply DC power to PA 
 
•  Adjust RF input level to the desired level, making sure that the output power does not 
exceed the maximum rated level for the Osprey SCPA (35W). 
 
2.3.3 Monitoring SCPA 
 
See PA’s Technical Specification for the alarm and control interface description. 
2.4 SCPA Specifications 
The detailed specifications are listed in the PA’s Technical Specification.  In the event of a 
conflict, the product specification takes precedent.
