MANAGEMENT
5.1 Overview
ThischapterdescribestheprotocolandmessagecommandandquerysetforcompleteremotemonitorandcontroloftheHPODSSPA.It
alsosummarizeskeyoperationalparametersandsomeoftheirmostcommonly‐usedremotecommandsandqueries.
5.2 Key Operational Parameters
SeeSect.5.5RemoteCommandsandQueriesfordetailedinformation abouttheremotecommandsandqueriesmentioned
inthissection.
5.2.1 RF Input Level
TheindividualamplifiermaximumgainandpowerratingdeterminestheRFinputlevelrequiredtoreachthefullratedoutputpowerof
theHPOD.

Forexample:IfthetestdataofanSSPAratedfor250W(54dBm)indicatedagainof75dB,thenasignalof54dBm–75dB=‐21dBm
wouldapproximatelygivethera tedoutputpower.

Increasinginputpower beyondthislevel resultsinanoutputsignal withincreasinglyhigher levelsof distortion.Of course,if the SSPA
attenuationcontrolisutilized,ahigher‐levelinputsignallevelcanbeaccommo dated.
