3.0 ImportantPrecautions
Observethefollowingsafetyprecautionstoensureusersafetyandmaximizingtheoperatinglife
ofthepreamplifier.

• Useonlythepoweradaptersuppliedwiththepreamplifier.
• Exercisecautionwhenhandlingthepreamplifierbecauseitissensitiveelectrostatic
discharge.
• Avoidusingthepreamplifierinenvironmentswithexcessiveheatormoisture.

Therearenootheruserserviceablepartsinsidetheunit.Donotremovethemaininstrument
cover.IfthepreamplifierneedsrepairpleasecontactauthorizedCom‐Powerservicecenter.
3.1ExcessiveRFinput
DonotexceedRFinputlevelindicatedonfrontpanel.ExcessiveRFinputmaydamagethe
preamplifier’ssensitiveinputandwillnotbecoveredunderwarranty.
3.2 Saturation
Inadditionpossibledamagetothepreamplifierinput,excessiveRFsignalsmaycausethe
preamplifiertosaturate.Whenapreamplifierreachessaturationpointthegainwillreduce
andcauseanonlinearincreaseinoutputpowerresultinginaccuratemeasurements.PAP‐501
canhandleupto+10dBm(117dBµV)inputsignal.
3.3Calibration
ThefactoryrecommendedcalibrationperiodforthePreamplifieris12months.However,its
performanceshouldbecheckedperiodicallytoensurethepreamplifierisoperatingwithinthe
ratedspecificationgiveninsection2.0ofthismanual.

5.4TroubleshootingCommonproblems

Problem:Gainislowornogain.

A:MakesurethepoweradapterispluggedinandthegreenisLEDislit.

Checkiftheinputandoutputcablesareconnectedsecurely.Wigglebothcablesandverifyifthe
signallevelchangesonthereceiver.Ifthesignalchangesreplacethedefectivecableandcheck
again.Makesurethecablefromthesignalsourceisconnectedtotheinputnottheoutput.

VerifyifthesignalsourceconnectedandRFisturnedon.Ifthesignalsourceisanantennaor
nearfieldprobesmakesuretheyareproperlyconnected.

Injectaknownsignallevelintothepreamplifierandcheckthegain.Forexampleifyouinject50
dBµV,youshouldread~71to73dBµVonthereceiver.Pleasebecautiousnottoexceedthe
inputlimitsgiveninspecificationtableofthismanual.
