Since the development and creation of various equipment and electronic devices, it has become necessary to measure radio waves and signals with special devices, since the human eye is not able to see the electric current and wave oscillations. Devices help to evaluate the strength of current fluctuations, interference and the amplitude of their movement. They are often used to test audio and video equipment.
What are oscilloscopes?
The device is classified according to several parameters:
- Operating principle: universal, special, speed, stroboscopic and memory.
- Number of signals: device for one, two or many channels.
- According to the method of displaying information: electron beam, matrix - plasma or liquid crystal.
- Data processing method: analog and digital oscilloscope.
To better understand an oscilloscope - what it is and how it works, let's find out what it consists of.
Device features
Universal analog oscilloscope includesyourself:
- CRT.
- Vertical and horizontal deflection channels (Y and X).
- Channel Z.
- Multimeter.
- Power supply.
Most modern models combine two functions: measuring direct and alternating current and displaying data on the screen. Universal models work only in one of the presented modes alternately. Digital devices are capable of simultaneously measuring signals and displaying calculated values. In addition, some models are equipped with the ability to print information. Recently, the latest measuring instruments have appeared: portable digital oscilloscopes.
Fluke Oscilloscopes
Equipment designed specifically for use in industrial and rather harsh conditions. Fluke's modern oscilloscope is built to the highest standards of performance and safety. The design is shock-resistant, with a maximum set of parameters. In addition, the instrument supports the function of a multimeter, registers the received data in the memory of the device, and it can be operated without the help of hands.
Here are some key features of Fluke oscilloscope models:
- Two- or four-channel.
- Frequency range: 60, 100, 200 and 500 MHz.
- Sampling rate up to 5 GS/s.
- Memory capacity: up to 10k samples per channel.
- Recorder mode recording up to 48 hours.
- An isolated port for connecting to a computer and other memory devices.
- Lithium-ion battery allows long and autonomous use of the device.
- Protected from dust and moisture.
- Security lock against unauthorized access.
This is the best tool for engineers and for most electronics repair needs.
