Виртуальный осциллограф «РадиоМастер»
![Виртуальный осциллограф "РадиоМастер"](https://www.radioradar.net/storage/files/preview_images/osc.webp "Виртуальный осциллограф "РадиоМастер"")
Виртуальный осциллограф «РадиоМастер» позволяет исследовать переменные напряженияв звуковом диапазоне частот : от 30..50 Гц до 10..20 Кгц по двум каналам с амплитудой от нескольких милливольт до десятков вольт. Перед реальным осциллографом такой прибор имеет преимущества: он позволяет легко определять амплитуду сигналов, запоминать осциллограммы в графических файлах. Недостатком прибора является невозможность увидеть и измерить постоянную составляющую сигналов.
На панели прибора располагаются органы управления, типичные для реальных осциллографов, а также специальные средства настройки и кнопки для работы в режиме запоминания осциллограмм. Все элементы панели снабжены всплывающими комментариями, и Вылегко с ними разберетесь. В скобках комментариев указаны клавиши, дублирующие экранные органы управления.
Характеристики осциллографа в значительной степени зависят отпараметров звуковой карты Вашего компьютера. Так со старыми типамикарт, у которых частота дискретизации не более 44,1 кГц, частотный диапазон прибораограничен сверху. Используя имеющийся на панели переключательчастоты дискретизации, опробуйте свою звуковую карту, и остановитесьна наивысшем возможном значении. Уже при 96 кГц можно увереннорассматривать сигналы до 20 кГц.
Разрядность АЦП установлена равной 16, что обеспечивает достаточно высокую точность.
Диапазон измеряемых осциллографом напряжений определятся резистивнымиделителями, смонтированными на кабеле (см. схему в помощи программы — «?»). При R1 =0 всенапряжение поступает на вход АЦП звуковой карты, следовательноможно без искажений рассматривать сигналы амплитудой не более 500..600мВ. При использовании резисторов указанных на схеме номиналовполучается диапазон напряжений до 25 В, что обычно достаточно в любительской практике.
Если ваша звуковая карта не имеет линейного входа, используйте вход микрофона, но при этом будет потерян один канал осциллографирования. Не забудьте указать выбранный вход звуковой карты в установках Windows. Соответствующий регулятор громкости установите в положение максимума, регулятор баланса в нейтральное положение.
Программа опробована под Win98 и WinXP.

It is a really easy to use oscilloscope that can be used to analyze signal waveform.
Other Oscilloscope Software
Above are the oscilloscope software that worked with signals from sound card via 3.5mm jack or USB mic. But, there are various other oscilloscope tools that require USB scope or other comm devices to receive and process signals. Some require USB scope to work, some work with Audrino, while some are Microcontroller based software. Some require proprietary tools to be connected to your PC to detect signals. Let me list some of such software that I stumbled upon while testing:
- USB Oscilloscope: USB scope
- UsbScope: USB scope
- Serial Oscilloscope: Audrino based.
- Scopino: Audreno based.
- PPMScope: Microcontroller based.
- ScopeShapes: Reads DXF files.
- Digital Storage Oscilloscope
- BitScope DSO
Each of these oscilloscope software were installed and tested, but didn’t work because of the lack of the signal input.
Сегодня у нас на обзоре радиолюбительская программа, которая превратит ваш домашний компьютер в осциллограф.
Есть два способа превращения персонального компьютера в осциллограф:
- Можно купить или сделать приставку, которую подключать к ПК. Приставка будет представлять собой АЦП, программно-управляемый. А на ПК установить соответствующую программу. Но это затратный способ.
- Второй способ – без затратный, в любом ПК есть уже АЦП и ЦАП – звуковая карта. Используя ее можно компьютер преобразовать в простой низкочастотный осциллограф, только установкой программного обеспечения, ну и придется спаять простой входной делитель. Таких программ существует не мало. Сегодня мы рассмотрим одну из них – Digital Oscilloscope V3.0.
После старта программы всплывет окно, которое внешне очень похожее на обычный осциллограф. Для подачи сигнала используется линейный вход звуковой карты. Подавать на вход обычно нужно сигнал не более 0,5-1 вольт, иначе происходит ограничение, поэтому нужно спаять входной делитель по простой схеме, как показано на рисунке.
Диоды КД522 защищают вход звуковой карты от слишком большого сигнала. После подключения цепи и входного сигнала нужно включить осциллограф. Для этого нажимаем мышкой поле RUN и выбираем START или нажать мышкой треугольник во втором сверху ряду окна. Осциллограф станет показывать сигнал. В нижнем правом углу экрана будут высвечиваться частота и период сигнала.
А вот напряжение показанное осциллографом может не соответствовать действительности. При налаживании входного делителя нужно постараться переменным резистором так выставить коэффициент деления, чтобы величина показанного на экране напряжения была максимально реальной.
Назначение органов управления. TIME/DIV – время/деление; TRIGGER – синхронизация; CALIB – уровень; VOLT/DIV – напряжение/деление. И еще одно достоинство этой программы – осциллограф запоминающий – работу можно остановить, а на экране останется осциллограмма которую можно сохранить в памяти ПК или распечатать.
