Tshajview

Moku: Lab software version 3.0 yog qhov hloov tshiab loj uas coj cov firmware tshiab, cov neeg siv cuam tshuam, thiab APIs rau Moku:Lab hardware. Qhov hloov tshiab coj Moku:Lab nyob rau hauv txoj kab nrog Moku: Fro thiab Moku: Mus, ua kom yooj yim los qhia cov ntawv hla txhua Moku platforms. Qhov hloov tshiab qhib lub tswv tsev ntawm cov yam ntxwv tshiab rau ntau yam cuab yeej uas twb muaj lawm. nws kuj ntxiv ob yam tshiab: Muti-instrument Hom thiab Moku Cloud Compile. Muaj qee qhov kev coj cwj pwm txawv txawv raws li tau teev tseg hauv Tshooj Backward compatibility.

Qhov kev hloov tshiab no tseem cuam tshuam rau APl architecture, thiab yog li ntawd cov pob API tshiab yuav tsis rov qab sib xws nrog cov ntawv APl uas twb muaj lawm. APlusers yuav tsum tau muab lawv cov ntawv xa mus rau Moku APl pob tshiab yog tias lawv hloov kho lawv Moku:Lab rau version 3.C. API cov neeg siv nrog kev tsim kho software tseem ceeb yuav tsum ua tib zoo xav txog qib ntawm kev siv zog uas yuav tsum tau ua rau chaw nres nkoj lawv cov coce uas twb muaj lawm. Moku: Lab 1.9 tsis pom zoo rau kev xa tawm tshiab thiab txhua tus neeg siv khoom raug txhawb kom hloov kho. Thaum kawg, Moku:Lab version 1.9 yuav poob kev txhawb nqa, raws li peb Txoj Cai Lij Choj Kawg. Yog tias muaj teeb meem tshwm sim tom qab hloov kho dua tshiab, cov neeg siv yuav muaj kev xaiv kom txo qis rau software version 19.

Phau ntawv qhia kev tsiv teb tsaws no qhia txog advantages ntawm kev hloov kho thiab muaj peev xwm teeb meem ntawm kev hloov kho rau Moku:Lab version 3.0. Nws kuj qhia txog cov txheej txheem los txhim kho lub LabVIEW APl thiab yuav ua li cas downgrade koj Moku:Lab yog tias tsim nyog.

Version 3.0 tshiab nta

Cov yam ntxwv tshiab
Software version 3.0 coj Multi-Instrument Mode thiab Moku Cloud Compile rau Moku:Lab thawj zaug, nrog rau ntau qhov kev ua tau zoo thiab kev siv tau hloov kho thoob plaws lub suite ntawm cov cuab yeej.

Multi-instrument hom
Muli-instrument Hom ntawm Moku:Lab tso cai rau cov neeg siv los xa ob lub cuab yeej ib txhij los tsim qhov chaw kuaj kev cai. Txhua lub cuab yeej muaj kev nkag mus rau cov analog inputs thiab outputs, nrog rau kev sib txuas ntawm cov ntsuas ntsuas. Kev sib cuam tshuam ntawm cov cuab yeej txhawb kev kub ceev, qis-latency, kev sib txuas lus digital hauv lub sijhawm txog li 2 Gb / s, yog li cov cuab yeej tuaj yeem khiav ntawm nws tus kheej lossis txuas nrog tsim cov teeb liab ua cov kav dej. Cov neeg siv tuaj yeem hloov pauv Cov Cuab Yeej hauv thiab tawm yam tsis muaj kev cuam tshuam rau lwm qhov uas nyob ib sab. Cov neeg siv qib siab tseem tuaj yeem siv lawv tus kheej cov kev cai algorithms hauv Multi-instrument hom siv Moku Cloud Compile.

Moku Huab Compile
Moku Cloud Compile tso cai rau koj siv cov kev cai digital teeb liab ua (DSP) ncaj qha mus rau Moku:Lab FPGA hauv Multi-instrument Hom. Sau code siv a web browser thiab sau nws hauv huab; tom qab ntawd siv Moku Cloud Compile los xa cov bitstreamto ib lossis ntau lub hom phiaj Moku.

Tsis-rov qab-tshaj hloov pauv

Data scaling in LIA
Hauv version 1.9, peb tau siv cov ntaub ntawv scaling xws li kev sib faib ob 0.1V DC cov teeb liab ua rau 0.02 V DC tso zis. Nyob rau hauv version 3.0, peb hloov qhov no xws li qhov tshwm sim yog 0.01V DC, uas yog ntau nyob rau hauv txoj kab nrog cov neeg muas zaub 'intuitive xav.

Waveform Generator tso zis yuav tsum tau ua kom siv los ua qhov kev hloov pauv / ua rau
Hauv version 1.9, ib qho sib txawv channel's waveform tuaj yeem siv los ua qhov kev hloov kho lossis qhov tshwm sim hauv Waveform Generator, txawm tias cov channel tso tawm tau raug kaw. Qhov no tau raug tshem tawm hauv version 3.0. Cov neeg siv uas xav ua qhov kev hloov pauv tsis tas yuav tsum tau tshem tawm cov khoom tawm ntawm lawv lub cuab yeej yuav tsum tau kho lawv cov kev ua haujlwm.

Moku LabVIEW API

Moku LabVIEW API pob yog npaj los muab LabVIEW tsim tawm cov peev txheej uas xav tau los tswj cov khoom siv Moku thiab, thaum kawg, muaj peev xwm los koom nrog cov kev tswj hwm no rau hauv cov ntawv thov loj dua.

New Moku LabVIEW API pob muab cov hauv qab no:

Moku API hloov

New Moku LabVIEW APl architecture txaus sib txawv los ntawm nws cov thawj coj thiab yog li ntawd tsis rov qab sib haum nrog API scripts uas twb muaj lawm. Cov nram qab no simplified Oscilloscope example qhia qhov sib txawv ntawm cov cuab yeej cuab tam thiab cov pob API tshiab thiab ua haujlwm raws li daim ntawv qhia kev rau kev xa cov lej uas twb muaj lawm.

Oscilloscope example
Daim duab 2: Oscilloscope APl kev sib piv

Ua raws cov kauj ruam

1. Pib Client kev sib kho thiab upload Oscilloscope bitstream rau Moku
2. Teem lub sij hawm puag thiab teeb tsa sab laug- thiab sab xis-sab tes rau lub sijhawm axis
3. Tsim waveform, configure, thiab tsim ib tug sinewave ntawm channel 1
4. Tau txais cov ntaub ntawv, tau txais ib lub thav duab ntawm cov ntaub ntawv los ntawm Oscilloscope.
5. CENITENES
6. Xaus Client session

Cov kab ke piav saum toj no yog ib qho yooj yim example los qhia txog qhov sib txawv ntawm cov cuab yeej cuab tam thiab cov pob khoom APl tshiab. Ib cag ntawm kev pib cov neeg siv khoom sib tham, upload cov cuab yeej bitstream rau Moku, thiab xaus rau cov neeg siv khoom sib tham, tus neeg siv kawg tuaj yeem siv ntau txoj haujlwm hauv ntau yam kom tau raws li qhov xav tau ntawm lawv daim ntawv thov.

Qhov txawv
Ntawm no, peb saib qhov sib txawv ntawm ob APIs rau txhua kauj ruam hauv cov kab ke.

1. Pib Maku-Client kev sib kho thiab upload Oscilloscope bitstream rau Moku
   APl tshiab tau faib cov neeg siv khoom sib txuas thiab xa cov cuab yeej bitstream rau hauv cov haujlwm sib cais, 1A thiab 1B. Tag nrho cov ntawv sau pib nrog cov haujlwm 2 no.
   
2. Teem caij puag
   Cov cuab yeej ua haujlwm hauv APl tshiab tam sim no yog ib qho haujlwm. Yav dhau los, qhov no yog 2-kauj ruam txheej txheem hauv API legacy. Thawj qhov ua haujlwm hloov cov kev nkag tsis tau rau JSON txoj hlua thiab lub vib nas this ua haujlwm xa cov lus txib mus rau Moku. Tsis tas li ntawd, kev ua haujlwm tsis zoo hauv cov cuab yeej cuab tam APlwere muaj nyob hauv pawg. Feem ntau ntawm kev ua haujlwm tsis muaj nyob hauv APl tshiab yog kev tswj hwm tus kheej.
