Yuav ntsuas suab nrov li cas nrog lub ntsuas hluav taws xob
Hauv app sau ntawv rau spectrum analyzers muaj kev sib tham txog kev kho 2.3dB uas xav tau thaum ntsuas suab nrov kom suav nrog cov txheeb cais sib txawv ntawm sinusoids vs. suab nrov vim lub cav amp, iIF lim, thiab lwm yam uas kuv tsis nco qab lawm.
Puas muaj qhov teeb meem zoo sib xws thaum siv lub ntsuas hluav taws xob nrog tus qauv diode sensor taub hau, zoo li E series. Yog tias muaj, puas muaj daim ntawv ceeb toom app ntawm qhov ntawd lossis nws puas zoo ib yam nrog cov ntsuas ntsuas spectrum.
Koj yuav tsum tau OK ntsuas suab nrov nrog E9300-series sensor.
Kev ntsuas suab nrov muaj ntau yam sib xws nrog cov teeb liab digitally modulated RF (xws li CDMA). Cov sensors tshiab dua li E9300-series tau tsim los ntsuas cov hom teeb liab kom raug, tsis muaj qhov yuav tsum tau kho.
Lub diode ua haujlwm nyob rau hauv cheeb tsam square-lawv yuav tsim cov zis proportional rau qhov nruab nrab lub zog ntev npaum li qhov siab tshaj plaws ntawm cov teeb liab ntsuas tau khaws cia hauv thaj tsam square-txoj cai ntawm lub diode (kwv yees.<-20dBm). This is true for the E9300 since they have a design with high power and low power diode stacks, so they are always using the diodes inside the square law region. The E4412A/E4413A CW sensors do not have this provision, so the operator must use care to keep the peak power <-20dBm if you want to use make this type of measurement.
Lub thermocouple sensor zoo li 8480 lossis N8480-series yuav zoo ib yam rau qhov ntsuas no.
