Matakan tallafi na lantarki (ESM): Yana aiki a matsayin gaba ga masu karɓar gargaɗin radar (RWR), yana aunawa da sauri, ganowa, da kuma gano ƙarfin siginar radar masu adawa don wayar da kan jama'a game da barazana da kuma samar da hotuna a yanayi.
Intelligence na lantarki (ELINT): Yana nazarin halayen bugun jini daidai (faɗin bugun jini, mita maimaituwa, iko) na siginar radar da ba a sani ba don rarrabe sigina da haɓaka bayanan sa hannu.
2. Tsarin sa ido da kula da bakan
Yana sa ido kan ayyukan sigina a faɗin faɗin mita a ainihin lokaci, yana auna matakan ƙarfin siginar tsangwama ba bisa ƙa'ida ba ko sigina masu abokantaka daidai. Ana amfani da shi don ganin yanayin yanayi, wurin tushen tsangwama, da duba bin ƙa'idodin bakan.
3. Kayan aikin gwaji da aunawa masu inganci
Ana iya amfani da shi azaman muhimmin tsarin gano wutar lantarki a cikin masu nazarin hanyar sadarwa ta vector (VNA), masu nazarin bakan, ko kayan aikin gwaji na musamman, wanda ke faɗaɗa ƙarfin auna kewayon wutar lantarki na kayan aiki, musamman ƙwarewa a auna ƙarfin bugun jini.
4. Tsarin Radar
Ana amfani da shi don sa ido kan sarrafa riba ta atomatik (AGC) a cikin tashoshin karɓar radar, sa ido kan fitowar wutar lantarki ta mai watsawa, ko yin aiki a matsayin sashin iyakancewa da gano wuta a gaban masu karɓar dijital (DRx) don kare abubuwan da ke da mahimmanci na gaba.
5. Sashen Bincike da Ƙwarewa a Sadarwa da Dakunan Gwaji
Ana amfani da shi don sa ido kan wutar lantarki da daidaita ta hanyar sadarwa a cikin tsarin sadarwa na intanet (misali, sadarwar tauraron dan adam, R&D na 5G/mmWave). A cikin dakin gwaje-gwaje, kayan aiki ne mai inganci don nazarin halayen siginar bugun jini da gwaje-gwajen share wutar lantarki.

Qualwave Inc. tana samar da na'urorin auna bidiyo na Detector Log waɗanda ke haɗa faffadan bandwidth, babban ji, saurin amsawa, da kuma kyakkyawan layi, tare da mitoci masu tsayi har zuwa 40GHz.
Wannan rubutun yana gabatar da na'urar ƙara bidiyo ta na'urar gano bayanai (Detector Log Video Amplifier) ​​wacce ke da ƙarfin mita na 0.5~10GHz.
