R& S ESR26 EMI Kev Ntsuas Hluav Taws Xob yog lub ntsuas kub uas ntsuas ntsuas lub tshuab hluav taws xob thaum lub sijhawm ib txhij ua haujlwm tam li muaj lub ntsej muag, cov teeb liab muaj zog thiab tsom xam cov tsom rau cov kev siv (lab). Kev ceev ceev-hluav taws-ceev ntsuas tshwm sim los ntawm ntsuas' s siv ntawm FFT-sijhawm sijhawm sau thiab txheeb xyuas cov ncauj lus kom ntxaws thiab keeb kwm kev cuam tshuam kev ua ub no tau ua tiav los ntawm kev ntsuas sijhawm tiag tiag uas siv ntau cov khoom siv txheeb xyuas. Qhov no muaj zog thiab compact, dual ntsuas yog cov neeg siv tus phooj ywg nrog nws cov ntawv qhia ncaj ncaj, kom paub meej touchscreen interface.
