SA-2500EX通信基站天饋線測試儀主要用于各種通信基站天饋線系統(tǒng)的測試。包括集群、GSM、PCS/DCS、CDMA、GPRS及尋呼系統(tǒng)等。在天饋線系統(tǒng)安裝、調(diào)測及日常維護(hù)時(shí)，對(duì)其進(jìn)行駐波比（VSWR），回波損耗、電纜損耗、功率及故障定位等測試。
SA-6000EX測試頻率: 25~6000MHz
SA-2500EX測試頻率:780~2500MHz
· 對(duì)初學(xué)者、偶爾使用及常用者均易操作
· 測量精確度及再現(xiàn)性高
· 在線現(xiàn)場測試抑制+13dBm(±10kHz)/+22dBm(±1MHz)的干擾信號(hào)
· 高清晰彩顯
· 快切換速率
· 同屏顯示測量比較圖
· 無限制查詢測試報(bào)告
· 兼容性強(qiáng)
快速識(shí)別細(xì)小的問題，防患于未然：
具有的高定向性及良好的源匹配特性，保證了匹配和故障定位測試的準(zhǔn)確性和重復(fù)性
· 60dB的高動(dòng)態(tài)范圍保證了細(xì)小故障的定位
· 高分辨率的標(biāo)記讀出駐波比數(shù)據(jù)，與昂貴的 實(shí)驗(yàn)室設(shè)備具有相同的精度
· 利用該儀器對(duì)現(xiàn)存的測量數(shù)據(jù)進(jìn)行轉(zhuǎn)換
· 可進(jìn)行電纜插入損耗測量
· 可搭配Bird數(shù)字功率傳感器測量功率
優(yōu)越的抗干擾能力，無限制條件的測試：
較高的干擾信號(hào)電平會(huì)影響其它同類測試儀的使用。該儀器具有較高的抗干擾能力，它能抑制高達(dá)+13dBm(±10kHz)/+22dBm(±1MHz)的干擾信號(hào)，因此可在無須關(guān)閉通信設(shè)備的情況下進(jìn)行現(xiàn)場天饋線分析
· 可顯示正反向功率，電壓駐波比，回波損耗
· 兼容MODEL 5010B功率傳感器
