Description
са от амплитуды входного (короткого) импульса , т. е. лииейпа амплитудна характеристика , что существенно в р де измерений . При этом пропорциональна передача формы входного сигнала и его фронтов не происходит. Это, возможно, вл етс недостатком расширител , но в большом классе измерений не играет роли (например, при измерени х пиковых значений мощности импульсных лазеров). Здесь важно измерить амплитуду импульсов и ее изменение, в то врем как длительность импульсов известна заранее. Так как измер ть короткие импульсы затруднительно (особенно с малой амплитудой ), то естественно применить расширитель длительности, который линейно передает амплитуду, существенно упроща весь измерительный тракт. Здесь также не играет роли и некотора задержка расширенного импульса относительно входного, в то врем как существенным вл етс низкий порог чувствительности и большой динамический диапазон по входному сигналу. Длительность фронтов расщиренного импульса должна быть такой, чтобы обеспечить отсчет амплитуды.It depends on the amplitude of the input (short) pulse, i.e., whether the pulse is amplitude characteristic, which is significant in a number of measurements. In this case, the transmission of the input signal form is proportional and its fronts do not occur. This may be a disadvantage of the expander, but does not play a role in a large class of measurements (for example, when measuring the peak power values of pulsed lasers). Here it is important to measure the amplitude of the pulses and its change, while the duration of the pulses is known in advance. Since it is difficult to measure short pulses (especially with a small amplitude), it is natural to use a duration expander that linearly transmits amplitude, greatly simplifying the entire measurement path. Here, the delay of the extended pulse relative to the input is also irrelevant, while the low sensitivity threshold and the large dynamic range of the input signal are significant. The duration of the fronts of the expanded pulse must be such as to provide an amplitude count.
