FEATURES
1.TheRFAS8810isaprogrammable,eight‐channeltestsubsystem,witha
frequencyrangeof0.8to3GHzandanattenuationrangeof0to110dB.
2.TheunitrunsontheWindowsoperatingsystem,andiscontrolledthrough
anRJ45EthernetinterfacebyTCP/IPprotocol.Inordertocontrolthe

userscanwritePCcontrolprogramsinVBScript,undertheRS232serial
communicationprotocol.
3.Theprogrammabletestsubsystemcansimplifytestsetups,suchas
handover,variablehandover,andfadeattenuator.Itsmostcommonuseis
inwirelesscommunicationsignaltests,inthestandard19‐inchrackpackage,
withhighaccuracyandstability.Inadditiontoadjustingtheunitremotely
throughLAN,RS‐232,orUSBinterface,youcanalsoeasilyadjustitinlocal
manualmode.WithalargeLCDdisplay,keyboard,andknob,thesub‐system
