    Project Description<\/h4>\n

    \u00dalohou bolo\/je zostroji\u0165 spo\u013eahliv\u00fd mera\u010d elektromagnetick\u00e9ho po\u013ea, schopn\u00fd odol\u00e1va\u0165 intenzit\u00e1m r\u00e1dovo 100 V\/m pri\u010dom mern\u00e1 intenzita po\u013ea je vo frekven\u010dnom p\u00e1sme 80 – 800 MHz s intenzitou 10 – 60 V\/m. Prv\u00e1 verzia meracieho pr\u00edstroja Pixla 1<\/strong> je auton\u00f3mna – schopn\u00e1 na vlastn\u00fd zdroj samostatne mera\u0165 a zaznamen\u00e1va\u0165 \u00fadaje cca 10 hod\u00edn, pri\u010dom zaznamen\u00e1va svoju polohu z \u00fadajov GPS a je \u010diasto\u010dne riadite\u013en\u00e1 pomocou WiFi. Pr\u00edstroj je v tienenej skrinke skon\u0161truovanej tak, aby do vn\u00fatra nevnikali ak\u00e9ko\u013evek cudzie sign\u00e1ly. Je mo\u017en\u00e9 mera\u0165 a uklada\u0165 tri frekvencie z\u00e1rove\u0148.<\/p>\n

    Pr\u00edstroj bude pou\u017eit\u00fd na merania smerov\u00fdch charakterist\u00edk ant\u00e9nnych syst\u00e9mov v\u00fdkonu 10- 100 kW pri predbe\u017enej kontrole alebo pri v\u00fdmene \u017eiari\u010dov.<\/p>\n<\/div>\n<\/div>\n

    The Challenge in the design<\/h4>\n

    Prev\u00e1dzka a odolnos\u0165 Pixle 1<\/strong> bola overovan\u00e1 v laborat\u00f3riu Elektromagnetickej kompatibility FEI STU. Zariadenie sa nach\u00e1dzalo v poli 50V\/m , pri\u010dom frekvencia po\u013ea sa prela\u010fovala od 80 MHz po 1 GHz. Zariadenie bolo nastaven\u00e9 tak, aby sa prij\u00edmal a zaznamen\u00e1val sign\u00e1l len s frekvenciou 96 MHz. Tento sign\u00e1l sa podarilo zachyti\u0165 s t\u00fdm, \u017ee nedo\u0161lo k zv\u00fd\u0161eniu pozadia nemeran\u00e9ho sign\u00e1lu (m\u00f4\u017eeme hovori\u0165 o ru\u0161en\u00ed). Pixla 1<\/strong> reagovala na zmeny amplit\u00fady line\u00e1rne so zmenou inciden\u010dn\u00e9ho sign\u00e1lu – elektromagnetick\u00e9ho po\u013ea. Nedo\u0161lo k prieniku elektromagnetick\u00e9ho po\u013ea do vn\u00fatra zariadenia \/ vn\u00fatra krytu in\u00fdmi cestami ne\u017e chcen\u00fdmi.<\/p>\n<\/div>\n

    Pri zapnut\u00ed frekven\u010dnej modul\u00e1cie na frekvencii 96 MHz\u00a0 bol zaznamenan\u00fd sign\u00e1l \/ d\u00e1ta stabiln\u00fd. Napriek zvy\u0161ovaniu frekven\u010dn\u00e9ho zdvihu frekven\u010dnej modul\u00e1cie sa zaznamen\u00e1van\u00e9 d\u00e1ta, pri kon\u0161tantnej \u00farovni ve\u013ekosti elektromagnetick\u00e9ho po\u013ea nemenili. Op\u00e4\u0165 nedoch\u00e1dzalo k zv\u00fd\u0161eniu pozadia meran\u00e9ho sign\u00e1lu, alebo zahlteniu \/ satur\u00e1cii pr\u00edstroja.<\/p>\n<\/div>\n<\/div>\n<\/div>\n
