Stanford Rechech la SR785 dinamik siyal Analyzer se yon presizyon, de chanel, plen Chin an tap Analyzer ki ofri eta-of-a-atizay pefomans nan yon pri ki nan mwens pase mwatye ki nan analyzers konpetitif. SR785 a se yon enstriman ideyal pou analize tou de sistem mekanik ak elektrik. Pou mezi ki enplike sistem servo, sistem kontwol, acoustique, tes vibration, analiz modal, oswa diagnostics machin, SR785 a gen karakteristik yo ak espesifikasyon yo ka resevwa travay la fe.
Gwoup mezi estanda yo enkli FFT, lod Suivi, octave, bale-sinis, korelasyon, kaptire tan, ak tan/histogram. SR785 a pote pouvwa a nan plizye enstriman nan aplikasyon ou: yon analyzer spectre, rezo analyzer, vibration analyzer, octave analyzer ak osiyoskop.
Yon Achitekti mezi inik pemet analyzer a fonksyone kom yon tipik chanel doub analyzer ak mezi tankou spectre kwa, repons frekans ak koneksyon. Altenativman, SR785 yo ka configuré pou ke chak fonksyon chanel opinyon kom yon analyzer chanel sel ak span pwop li yo, frekans sant, rezolisyon ak moyenne. Sa a pemet ou we yon espek laje-bann ak ansanm rale nan sou detay espek Etwal. Menm Achitekti a avanse bay depo nan tout blok bilding mezi ak mod moyenne. Vekte mwayenn, rms mwayenn, unaveraged, ak pik kenbe vesyon nan tout mezi yo ansanm yo te akeri epi yo ka Paret san yo pa re-pran done.
