Zvasara zviri pedyo ne high-impedance input, coupling kubva ku converter kana hardware profile isiriyo inzira dzekuongorora. Chikonzero chaicho chinofanira kusimbiswa necircuit yakaburitswa uye controlled test setup.

Zvishandiso zvese zvinoona mwaranzi zvinobatwa nemaoko zvinoda maPCB ane simba guru here?

Kwete. Dhizaini yeGM-tube inowanzo kuve nechinodiwa che high-voltage bias, asi magadzirirwo e semiconductor uye scintillation detector anosiyana. Mudziyo wekunzwa wakasarudzwa unosarudza kana voltage yakakwira ichidiwa uye kuti ndeipi imwe low-noise circuitry kana module interface inodiwa.

Chii chinofanira kukumbirwa kuti Highleap itaure zvakasiyana?

Tsvaga chero mamodule ekuona akatumirwa, zvishandiso zvekuedza zvinoshanda, kucheneswa kana kubata kwenyanzvi, kuiswa kwemamodule mushure mekuunganidza, uye kuyera kana kubvumidza kunze kwePCB/PCBA yakajairika. Musiyano iwoyo unoita kuti makotesheni nemabasa ekugamuchira zvive pachena.

Zvinodiwa pakugadzira, kuunganidza uye kuyedza PCB zvinosimbiswa zvichienderana nedhizaini yakaburitswa, mirairo yemupi wezvikamu uye chero zvinodiwa zvekufanirwa kwekugadzirwa kwechigadzirwa chekupedzisira.
