How to build an oscilloscope with their hands

Electronic oscilloscope - an irreplaceable thing in the workplace, in the home or learning laboratory.This measuring device provides a glimpse into the work of electronic circuits, featuring on-screen dynamics of change in the input potential.It is indispensable when setting high-power thyristor converters in production.Good help for troubleshooting electrical circuits, control, protection or process control, significantly reducing downtime.

Collect oscilloscope hands - hardly feasible task for radio, but only if the go the traditional route, trying to imitate the work of modern instrumentation.It is an analogue and digital devices that are manufactured on an industrial scale.

picture changes radically, if the compute node and visual control of the measured voltage to use home PC.Speed ​​of modern processors is capable of solving any problems, and a large monitor for monitoring the measured signal is only a plus.We can only collect a small circuit, and you make an oscilloscope with his hands.The device does not require any pre-setting.

Let's look at the main part of the product.The scheme itself and the program to flash the controller, you can easily find in the specialized literature.Typically, the device has one or more analog inputs.By installing an adjustable divider on one of them, you can change the amplitude of the input signal.This is done to extend the measurement range of the device.As protection against excessive voltage set parametric stabilizer or any other device that limits the level of the input voltage.All analog inputs can be connected to the input of the microprocessor outputs are connected to a connector for connecting the device to USB-port.Power circuit by using the same port.

Thus, we have made the oscilloscope with their hands, but to run the device, you must program the microcontroller interface and install a program to recognize the input signals to your computer.The controller is programmed using the programmer and is set to cost.Just To install the necessary software on your computer.You guessed it, you have made your usb-oscilloscope with his hands.The main requirement - all operations for the installation and programming must be carried out correctly.

As you can see, a digital oscilloscope with your hands to make a snap.The speed of this device allows you to configure, repair, or learn how to use simple electronic circuits.Such a device is useful in a home lab.

To increase the speed of the device is used several ways, but they all lead to a complication of the original scheme.For switching the device to your computer, you can use a parallel port, it will bypass the sampling rate of USB-ports and raise performance.

In addition, there are special cards that are inserted into a computer and used to process the input signals.
