PSM4320 chastotali quvvat o'lchagichining maqsadi: Tektronix PSM4000 seriyali quvvat o'lchagichlari kuchli va ulardan foydalanish oson. Ular o'rtacha quvvat (CW) o'lchovlarini ta'minlaydi va impulsli chastotali va mikroto'lqinli signallar bilan ishlashda qo'shimcha ravishda impuls va eng yuqori quvvatni o'lchaydilar.
