Abstract:This paper conducts an in-depthanalysisof the phenomenonofabnormal fluctuations inthe telemetry signalofa specificmodelreceiverundervibrationalstressconditionsanddiscussescorresponding treatment measures.The telemetrylevel, asoneofthekeyparametersofthereceiver,hasitsstabilitydirectlylinkedtothreceiver'seliabilityandaccuracy.Tis paper outlinestebasicprinciplesofthereceiveranditsimportance,describesthespecificmanifestationsofabnormalfuctuations, analyzesvariouscauses ofthe fluctuations,performs fault localizationand mechanismanalysis,andreveals the fundamental causeof abnormalfuctuations.Itproposes alow-cost treatment methodofreinforcing thelocaloscilatorunit withsilverpaste adhesive,verifiesthefeasibilityoftismethod,anddemonstratesthatthistreatmentmethodcanbeappliedinthedesignof similar low-phase noise electronic products.
