Measuring receiver (original) (raw)
In telecommunication, a measuring receiver or measurement receiver is a calibrated laboratory-grade radio receiver designed to measure the characteristics of radio signals. The parameters of such receivers (tuning frequency, receiving bandwidth, gain) can usually be adjusted over a much wider range of values than is the case with other radio receivers. Their circuitry is optimized for stability and to enable calibration and reproducible results. Some measurement receivers also have especially robust input circuits that can survive brief impulses of more than 1000 V, as they can occur during measurements of radio signals on power lines and other conductors.

Основное назначение их — напряжения или мощности слабых сигналов, у многих современных приёмников есть также дополнительные функции, например: анализ спектра сигнала, измерение модуляции, сканирование по диапазону частот с целью выявления каналов, на которых ведется передача или для отслеживания помех. Для определения параметров радиоизлучения в пространстве, измерительный приёмник используется совместно с измерительными антеннами. От измерительных приёмников следует отличать и , которые не измеряют параметры радиосигнала, а принимают измерительную информацию, передаваемую специальными радиостанциями. (ru) |
