Paunotenga nesu, haungongowana zvigadzirwa zvepamusoro zvinovandudza mararamiro ako, asi uchagamuchirawo chipo chakasarudzika chemahara nechero odha yaunoisa. Wagadzirira kuongorora kuunganidzwa kwedu uye kuwana zvipo zvako zvakakwana? Tarisa sarudzo yedu yezvinhu zvedhipatimendi repamusoro, isa odha yako, uye tarisira kunakidzwa kwechipo chako chemahara kusvika pamwe nekutenga kwako.

Mutemo Wekutumira

Tichashanda nesimba kutumira zvinhu kwauri mushure mekugamuchira maodha ako uye kuve nechokwadi chekuti zvinosvika zvakachengeteka. Ruzivo rwekutumira rwuchapihwa muemail yako yekusimbisa.Kazhinji, maodha anogadziriswa mukati memazuva maviri.Pasi pemamiriro ezvinhu akakosha, zvinononoka seinotevera: Paunoisa odha neMugovera, Svondo kana mazororo, zvinononoka kwemazuva maviri.Kazhinji, zvinoda mazuva mashanu kusvika manomwe ekushanda (Muvhuro kusvika Chishanu) pasina kukanganiswa nekunonoka kwendege kana zvimwe zvinhu zvemamiriro ekunze.Sezvo basa redu rekutumira riri pasi rose, nguva dzekutumira dzinoenderana nenzvimbo yako saka zvingatora nguva shoma uye ndapota mirira nemoyo murefu kana iwe uri mumatunhu ari kure kana nyika.

1. Kudzoserwa & Kuchinjaniswa Mutemo

Tinogamuchira chete zvinhu zvakatengwa kubva roymall.com. Kana iwe ukatenga kubva kune vedu vekutengesa kana vamwe vatengesi, haugone kuzvidzosera kwatiri. Zvinhu zvekupedzisira kutengeswa kana zvipo zvemahara hazvigamuchirwe kudzoserwa.Kuti ukwanise kudzosa, chinhu chako chinofanira kunge chisina kushandiswa uye chiri mumamiriro akafanana neawachigamuchira. Chinofanirawo kunge chiri mupakeji yepakutanga.Mushure mekugamuchira mirairo yekudzosa kubva kwatiri, ndapota pakeja zvinhu zvako zvakadzoserwa uye donhedza pasuru yako kuposvo yemuno kana imwe courier.Tichagadzirisa chinhu chako chakadzoserwa kana kuchinjaniswa mukati memazuva matatu kusvika mashanu ekushanda mushure mekunge tagamuchira. Mari yacho ichagadziriswa uye yozopihwa otomatiki kune yako yekutanga nzira yekubhadhara.Hapana kudzoserwa kana kuchinjaniswa kunogona kugamuchirwa kana chigadzirwa chakagadzirwa netsika, kusanganisira saizi yakagadziridzwa, ruvara rwakagadziridzwa, kana kudhinda kwakagadziridzwa.Unoda rumwe rubatsiro, ndapota taura nesu. service@roymall.com kana Whatsapp: +8619359849471

2.Mutemo Wekudzoserwa Mari

Features:

- With DC dimming method, 4" full-view LCD screen can be seen more clearly for outdoor uses, and more comfortable for indoor uses.

- Optimized Electric Bridge: Making full use of the harmonics of Si5351, it can use the 5th harmonic to measure up to 1.5GHz.

- When fundamental wave is used, the output level of CH0 is increased to 0dBm, making reflection measurement more accurate.

- Solved the abnormality of NanoVNA-H when operating at around 6MHz before.

- Redesigned power management circuit reduces power noise, USB power interference, and charging current.

- Improved PCB layout.

- Reserved UART interface for DIY expansion.

- Lightweight ABS shell keeps the device well protected.

-Computer software supports control and real-time display. And it support for exporting snp files for various radio design and simulation software.

- As a measuring device, accuracy is of great importance. Simple calibration parts are included in the package. We have calibrated the product"s dual ports before delivery. When your measurement conditions change (for example, switching from a narrower calibration bandwidth to a wider measurement bandwidth with an extension cable measurement), you need to re-calibrate. After calibration, it is saved as setting 0, which can be used directly at the next boot, or it can be saved to the other 4 saved items through recall when needed.

Parameters:

1. ABS Shell: 75mm x 133mm x 18mm (excluding protrusions)
