Lub Rohde& Schwarz SMA 100 B RF thiab microwave teeb liab lub tshuab hluav taws xob muab cov paib tso tawm qhov tseem ceeb tshaj plaws thaum tswj kev ua haujlwm siab tshaj plaws, ua kom deb tshaj qhov sib tw. Rau LO hloov chaw nyob rau hauv cov ntawv thov radar, SMA 100 B tuaj yeem tsim cov teeb tsa microwave nrog qhov tsis tshua muaj qhov ze-nyob rau SSB theem suab nrov, ua rau lub tshuab radar txhawm rau paub txog cov khoom qeeb heev. Txog kev sim cov analog-rau-digital hloov (ADC), Rohde& Schwarz SMA 100 B ua cov cim taw qhia nrog lub suab qis dav dav. Tib lub teeb tsa hluav taws xob muaj peev xwm muab tau lub teeb tsa hluav taws xob ntshiab ua rau lub zog ADC. Thib ob, qhov tso tawm ywj siab tuaj yeem muab cov cim taw qhia rau ADC kuaj nrog qis dua dav dav theem suab nrov.
Nrog Rohde& Schwarz SMA 100 B, nws tsis tas yuav xaiv ntawm teeb liab purity thiab qib siab tso zis hluav taws xob. Nws yog tib lub teeb liab hluav taws xob uas tuaj yeem muab cov teeb liab nrog ultra siab tso zis hluav taws xob ua ke nrog cov tsis tshua muaj teeb meem tsis tshua muaj teeb meem ua kom raug mob, teeb tsa cov qauv tshiab rau highend cov teeb liab ua hluav taws xob. Txawm tias ntawm lub zog tso zis ntau dhau los, kev sib raug zoo raug tsim los ntawm ntau dua ntawm 70 dBc dhau ntawm ntau qhov ntau, qhov muaj txiaj ntsig zoo thaum ntsuas lub suab' SMA 100 B kuj tseem muaj qhov tshwj xeeb 1 GHz siv tawm. Lub 1 GHz muab qhia zoo dua qib ntsuas phoo txuas ntawm ntau SMA 100 B tshaj qhov ntawm 10 MHz siv. Qhov 1 GHz tso tawm kuj tseem muaj cov teeb liab zoo nkauj.
Cov Lus Qhia rau Qhov Uas Suav:
● Zoo heev SSB theem suab nrov hauv lub hauv paus tsev: - 119 dBc (ntaus ntawv.) Rau 10 GHz ntawm kev ntsuas ntawm 20 kHz
● Zoo tshaj SSB theem suab nrov nrog kev xaiv: - 132 dBc (typ.) Rau 10 GHz ntawm kev kho ntawm 10 kHz
● Qes qis tshaj-nyob hauv SSB theem suab nrov: - 83 dBc (ntaus ntawv.); f= 10 GHz, offset= 10 Hz
● Lub suab nrov tsis muaj suab nrov: - 162 dBc (meas.) Ntawm 10 GHz thiab kev faib tawm ntawm 30 MHz
Saib Cov Ntaub Ntawv rau tag nrho cov kev qhia tshwj xeeb
Cim npe nrov: siv cov cim hluav taws xob ua tawm rohde&schwarz sma 100 b, tuam ntxhab, yuav, nqi qis, hauv Tshuag
