CNT-91 tavsifi: Foydalanuvchi tomonidan belgilangan chegaralar doirasida chastotani, davrni, fazani va ish tsiklini yuqori aniqlikda o'lchash, vaqt va chastotani kalibrlash va tahlil qilish, o'lchov natijalarini statistik qayta ishlash va olingan ma'lumotlar bilan matematik operatsiyalarni bajarish uchun mo'ljallangan. 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.
