R& S ESR7 EMI Test Receiver yog lub cuab yeej ntsuas ob uas ntsuas lub ntsuas hluav taws xob tsis sib haum thaum ib txhij ua haujlwm raws li lub ntsej muag ua kom pom tseeb, muaj zog teeb liab thiab spectrum analyzer rau cov ntawv thov siv. 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.
