Internal tsom xam ntawm ib tug handheld oscilloscope
Txoj kev ntes
Peak nrhiav pom - txhua ob lub sijhawm kuaj pom tau suav tias yog lub sijhawm kuaj pom qhov siab tshaj plaws, thiab qhov siab tshaj plaws thiab qhov tsawg kawg nkaus yog coj mus kuaj nyob rau lub sijhawm, uas yog siv los ua cov ntsiab lus piv txwv los tsim ib lub waveform. Txoj kev ntes no yog siv los ntes cov zaus thiab qhov tsis sib xws. Glitters nqaim li 10ns tuaj yeem ntes txhua lub sijhawm ntsuas los ntawm 5μs / div txog 5s / div.
Sampling - Sampling ntawm cov ntaub ntawv ntawm lub sijhawm sib npaug.
Qhov nruab nrab - nruab nrab ntawm 2 txog 512 (yeem) cov ntaub ntawv khaws cov ntaub ntawv waveform.
Lub hnab ntawv - Qhov siab tshaj plaws / yam tsawg kawg nkaus tau txais ntawm ib lossis ntau qhov kev ntes.
trigger system
1. Lub ntsiab triggering hom - tsis siv neeg (txhawb 0.5s/div thiab qeeb scrolling hom), ib txwm.
2. Lub hom phiaj
Edge-Conventional theem-tsav triggering. Qhov zoo thiab qhov tsis zoo nqes ntawm txhua qhov channel. Kev xaiv coupling: DC, suab nrov suppression, siab zaus suppression, tsawg zaus suppression.
Sab nraud txhais - txhawb 5MHz TTL qib, xaiv tau 200mV ~ 2V txhais theem;
Video - Koj tuaj yeem xaiv ua rau ntawm thaj chaw lossis kab ntawm cov yeeb yaj kiab, ua rau NTSC, pAL lossis SECAM tshaj tawm cov qauv video;
Lub cev muaj zog trigger: Ua rau ntawm 3- thiab 5- theem pulse width modulation power signals. Txoj haujlwm no tsuas yog siv hauv THS720p.
3. Lub hauv paus chiv keeb: ib qho channel, sab nraud trigger channel, sab nraud trigger channel / 5, mains hwj chim;
4. Cov zaub ua kom pom: tuaj yeem tso saib cov theem ua haujlwm;
5. Cursor system:
Hom: kab rov tav kab, kab ntsug, kab ua ke;
Vernier ntsuas: Δvolts, Δtime, 1 / Δtime (Hz), degrees (theem).
lub sij hawm base system
1. Kab rov tav zoom: Kab rov tav zoom nyob rau hauv los yog tawm ntawm static los yog dynamic waveforms. Koj tuaj yeem siv lub qhov rais xaiv ib cheeb tsam tshwj xeeb kom zoom hauv thiab saib los ntawm kev nthuav lub qhov rais.
2. Sijhawm/qib ntau yam: -5ns~5s/div;
3. Cov ntaub ntawv ntev: 2500 ntsiab lus;
4. Kab rov tav raug: ±0.01%;
5. Lub sij hawm puag stability: 200ppm.
ntsuas qhov system
1. Tsis siv neeg waveform ntsuas - cia li ntsuas 21 tsis: lub sij hawm, zaus, zoo mem tes dav, tsis zoo mem tes dav, zoo overshoot, tsis zoo overshoot, siab tus nqi, qis tus nqi, siab tshaj, yam tsawg kawg nkaus tus nqi, ncov-peak, amplitude, nruab nrab, lub sij hawm nruab nrab , lub hauv paus txhais tau tias square, lub sij hawm hauv paus txhais tau tias square, nce lub sij hawm, lub caij nplooj zeeg lub sij hawm, zoo lub luag hauj lwm voj voog, tsis zoo lub luag hauj lwm voj voog, tawg dav, muaj peev xwm tso saib plaub waveform ntsuas qhov tseem ceeb nyob rau hauv ib tug ua ke.
2. Qhov chaw pib - Ntau qhov chaw pib tuaj yeem teeb tsa raws li feem pua lossis qhov hluav taws xob, piv txwv li, nce ntug ntawm 10% mus rau 90% (los yog 0.1V txog 0.9V)
3. Cov tswv lag luam suav - sib ntxiv, rho tawm, sib npaug, suav cov nqi hluav taws xob U × I;
