Tus Qauv Tshawb Fawb ntawm Stanford (SRS) DS340 yog 15 MHz ua haujlwm thiab kev siv lub tshuab hluav taws xob tsis ncaj ncees raws li Direct Digital Synthesis (DDS). Kev sib xyaw ua ke ntawm cov yam ntxwv, kev ua haujlwm thiab tus nqi qis ua rau SRS DS340 Generator zoo rau ntau yam sim thiab ntsuas cov ntawv thov.
Sine nthwv dej thiab cov voos xwm txheej tuaj yeem tsim nyob ntawm ntau zaus txog 15.1 MHz, thiab cov nplais thiab cov duab peb ceg ntev txog 100 kHz. Zaus daws teeb meem yog 1 µHz rau tag nrho cov haujlwm. SRS DS340 Kev Ua Hluav Taws Xob kuj suav nrog lub tshuab hluav taws xob 10 MHz Gaussian dawb-nrov nrov.
Tag nrho cov haujlwm tuaj yeem raug swept logarithmically lossis linearly hauv ntu-txuas ntxiv kev zam dhau ntawm txhua qhov ntau ntawm qhov ntsuas. Lub nraub qaum-vaj huam sib luag SWEEP tso tawm cov paib qhia qhov pib teeb tsa thaum pib cheb tso cai rau synchronization ntawm cov khoom siv sab nraud. Ob leeg qhov kev ua haujlwm thiab kev sib tw yuav tsum raug xaiv.
Txog 16,300 qhov ntsiab lus txog kev yoj ua qauv tuaj yeem rub tawm rau SRS DS340 Generator' s waveform nco txog ntawm kev xaiv GPIB lossis RS-232 cuam tshuam. PC software yog muab rau kev xam, kho thiab rub teeb tsa ua plaub tsis txaus ntshai. Lub koob yeem nco tau tuaj yeem ua si rov qab ntawm tus nqi nce mus txog 40 Msamples / s.
Ob hom sab hauv thiab sab nraud FSK tso cai rau cov zis tawm kom nrawm nrawm ntawm ob qhov kev coj ua ntej. FSK toggling tuaj yeem ua rau sab hauv (ntawm tus nqi nce txog 50 kHz), lossis tawm sab nraud ntawm lub rooj tsav tsheb tom qab.
Arbitrary Waveform Composer (AWC) software muab pub dawb. AWC yog qhov yooj yim, cov ntawv qhia ua zaub mov raws txoj cai uas tso cai rau koj tsim thiab kho cov ntaub ntawv tsis zoo ntawm lub vijtsam, khaws cia thiab rub tawm mus rau SRS DS340 Generator.
