  1. The signal generator of sweep frequency is based on dds device ad9954, the signal measuring circuit is based on gain and phase detector ad8302, the real - time control and deal circuit is based on tms320vc5409, and the periphery interface circuit is based on at89s52. the system can generate sweep frequency signal with the frequency range from 100khz to 150mhz, and with the power range from - 45dbm to + 18dbm. it can measure the gain and phase of the network, display the measure data by liquid crystal displayed and print it by the printer

    該測試儀以dds晶元ad9954為核心構成掃頻信號源電路，以增益相位檢測器ad8302為核心構成檢測電路，以dsp晶元tms320vc5409為核心構成控制與運算電路，以及以at89s52為核心構成外圍介面電路。該測試儀能產生頻率范圍達100k ~ 100mhz ，功率范圍為- 45dbm ~ + 18dbm的掃頻信號，能對被測網路的頻率特性進行測量，並留有豐富的外圍介面，可以將測量數據繪圖通過lcd顯示或者由印表機列印輸出。
