Oscilloscopes

Oscilloscopes are the basic measuring instruments used in electronics. They are known to all electronic engineers, both beginners and already experienced amateurs and professionals. The oscilloscope is used to observe deformed electrical waveforms and is also used to measure various parameters that relate to these waveforms. Nowadays digital oscilloscopes are used, the prototype of which was an analogue oscilloscope. They differ not only in the way and mechanism of operation, but also in the construction and precision of measurements. Digital oscilloscopes have a built-in sample memory and are used not only to measure periodic signals but also to observe random events, sometimes single pulses. A well-fitting oscilloscope enables the removal of the dynamic and static characteristics of electronic instruments. Moreover, with its help we can measure their phase shift.

Operating principle of the oscilloscope

Digital oscilloscopes that we use today much more often than their analogue equivalents, are very technologically advanced devices. They are distinguished by low noise and very high speed of the sensor. In such a device we can also find many additional systems which facilitate making measurements and increase the possibility of observation. The course of voltage is recorded from the moment the voltage level set by the user appears, as well as its increase or change. The course of the voltage is registered in the form of samples for a fixed time. We see it on the device screen. It is also possible to observe the image on the computer monitor when we connect the oscilloscope to the computer with a USB cable. Oscilloscopes differ in functionality and additional options. One of them is the possibility to freeze the image and thus stop it. This is useful when analyzing it. The oscillogram, and thus the recording of the voltage, is used to measure the amplitude and timing of the signal. Oscilloscopes are also equipped with automatic measurement functions. These include rise time, frequency and drop time of the signal. It is not necessary to calculate these parameters by yourself.

Mobile oscilloscopes

The simplest of these measuring devices are mobile oscilloscopes, which you connect to a USB port on your computer. They are characterized by their small size and high mobility. They are also called attachments. Their memory allows you to record and transmit measurement results. Usually such a device consists of two independent channels, whose maximum frequency is 20 MHz. Some models additionally have a built-in multimeter. It is worth mentioning the complementary functions, such as course measurements and mathematical calculations, concern difference, sum, quotient and product. It is possible to filter input signals through one of four digital filters that are located in each channel. These filters are: high-pass, low-pass and band-stop.

Choosing the right oscilloscope

When choosing an oscilloscope, it is important to consider its purpose and the area where it will work. If you are looking for a service device, a stationary oscilloscope with a frequency range that meets the requirements of the equipment being repaired will be a good choice. You will also find mobile oscilloscopes, such as Nano VAS or Quad VAS, which are designed for mobile use. They are smaller in size, but their functionality and capabilities do not differ from stationary devices. Particularly noteworthy is the BitScope Micro M5 oscilloscope, which is distinguished by its above-average small size. It is worth to opt for it if it is to be used to run simple systems. It is also an ideal option for beginner oscilloscope users.
