SM200B – быстродействующий анализатор спектра реального времени с широким динамическим диапазоном, низким уровнем собственных фазовых шумов и функцией мониторинга спектра. Соединение с компьютером пользователя осуществляется по высокоскоростной шине USB3.0 SuperSpeed. Устройство имеет ширину полосы анализа 160 МГц в реальном времени, 40 МГц – в режиме записи данных, диапазон рабочих частот от 100 кГц до 20 ГГц и скорость сканирования 1 ТГц/с при полосе RBW 30 кГц. Оцифровка происходит со скоростью миллиард выборок в секунду. Анализатор спектра SM200B использует опорный генератор OCXO 100 МГц с очень низкими фазовыми шумами. SM200B имеет высокое значение показателя IP3 и низкий отображаемый средний уровень шумов (DANL), позволяющие пользователю исследовать спектр сигнала с достаточной чувствительностью и без проблем с дополнительными интермодуляционными спектральными составляющими. SM200B имеет встроенный приемник системы GPS для простановки временных меток в анализируемых сигналах.
