CNT-90 chastota o'lchagichining maqsadi: CNT-90 universal taymerlari / hisoblagichlari / analizatorlari chastotani, davrni, fazani va ish tsiklini foydalanuvchi tomonidan belgilangan chegaralar doirasida yuqori aniqlikda o'lchash, vaqt va chastotani kalibrlash va tahlil qilish, o'lchov natijalarini statistik qayta ishlash va matematik operatsiyalarni bajarish uchun mo'ljallangan. olingan ma'lumotlar. GPIB / USB interfeysining mavjudligi qurilmani shaxsiy kompyuterga ulashga imkon beradi va TimeView dasturidan foydalanib o'lchov natijalarini ro'yxatdan o'tkazadi, tahlil qiladi va arxivlaydi. Ushbu ketma-ketlikning chastota o'lchagichlari grafik interfeysga va rivojlangan o'lchov boshqaruviga ega.
