4.1.4 Inspection
Before applying primary power, check the power amplifier chassis for foreign matter.
Remove any foreign material from the chassis. Be sure that the front air louvers and fan
assembly are unobstructed; the fan should turn freely and operate when power is applied to
the PA. Check to be sure connectors on the back panel are securely fastened. Also check
other rack wiring and cables for secure termination.
4.1.5 Power Requirement
The power amplifier requires a 28 volt dc supply to operate as specified. Total supply
current varies depending on transmitter model, other racked equipment, and RF output.
One GL-T8541 PA (with exciter) requires approximately 644 watts of dc power when
operating at rated RF output. See section two for more information.
4.1.6 PA Module External Connectors
The metering board is mounted on the outside of the rear panel of the PA module. Metering
board interconnection to the PA module is accomplished through a D-sub 25 connector. RF
input to the PA is through a rear access N-type connector. RF output is through a rear access
N-type connector. Refer to Figure 4-1, for external PA cabling information.
