To'lqinlovchining o'zgaruvchan atletuatorlari doimiy ravishda aylanadi
To'lqinlovchining o'zgaruvchan atletuatorlari
Mikroto'lqinli ohanglarda signallarning kuchi ko'pincha juda yuqori. Agar ortiqcha quvvat to'liq nazorat qilinmasa, u tumandagi energiya komponentlarining maksimal energetikalar doirasidan oshib ketishi va turli xil og'ishlarni keltirib chiqarishi mumkin. Tig'irsevide o'zgaruvchan attudalardan foydalanish signal kuchini kamaytirish va mikroto'lqinli slankalarning normal ishlashini ta'minlashi mumkin.
Doimiy attenatorning ishlash printsipi to'lqinliq to'lqinlardagi elektromagnit to'lqinlarning targ'ibot xususiyatlariga asoslanadi. U asosan to'lqinlarning, egilib mos keladigan qurilmalar va o'zgaruvchan dirijyor bloklaridan iborat. Agar signal to'lqin bilan shug'ullansa, energiyaning bir qismi dirijyor bloki tomonidan so'riladi va bu bilan signal kuchini kamaytiradi
Ishlovchilar blokirovkasi foydalanuvchi tomonidan qo'lda sozlanishi mexanik tuzilish bo'lsa, u aylanadigan qadam bosgan attadir. Qo'lda o'zgaruvchan attranslar elektron aloqa tizimlarida zaruriy ta'minotchilardir.
Ilova:
1. Signal zanjiridagi signal darajasining muvozanatini o'zgartirish signal kuchini pasaytirish orqali to'lqinli attudalarga erishish mumkin.

To'lqinning o'zgaruvchan attenator mikroto'lqinli aloqa va laboratoriya sinovida keng qo'llaniladi. Bu turli xil ehtiyojlarni qondirish uchun signal kuchini o'zgartirish uchun ishlatilishi mumkin. Masalan, laboratoriyada aylanish darajasi sinov uskunalarini sinab ko'rish uchun o'zgarishi kerak bo'lganda moslashuvchan sozlash qobiliyatini ta'minlaydi. Mikroto'lqinli aloqa, uzluksiz o'zgaruvchilar uzluksiz attudalarni uzatish paytida juda kuchli yoki juda zaif emasligini ta'minlash uchun signal kuchini sozlash uchun ishlatilishi mumkin.
O'zgaruvchan attudalarning afzalliklari soddaligi, foydalanish qulayligi va moslashuvchan sozlash. Qo'lda ishlov berish natijasida foydalanuvchilar kerak bo'lganda signallarni aniqlashning miqdorini aniq boshqarishi mumkin. Biroq, avtomatik to'lqinlovchelni attenatorlari bilan taqqoslaganda, qo'lda to'lqinli attenatorlarining torayishi torayib ketishi mumkin va sozlash jarayoni ma'lum vaqt va aniqlikni talab qiladi.
