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 electric current and wave oscillations. Devices help to evaluate the strength of the current fluctuations, interference and the amplitude of their movement. Often they are used to test audio and video equipment.
What are the oscilloscopes?
The device is classified according to several parameters:
- Principle of action: universal, special, high-speed, stroboscopic and memory.
- Number of signals: device for one, two or many channels.
- By the method of displaying information: electron beam, matrix - plasma or liquid crystal.
- Data processing method: analog and digital oscilloscope.
To better understand the oscilloscope - what it is and how it works, we learn what it consists of.
Instrument Features
A universal analog oscilloscope includes:
- Cathode ray tube.
- Channels of vertical and horizontal deviation (Y and X).
- Channel Z.
- Multimeter.
- Power Supply.
Most modern models combine two functions: measuring direct and alternating current and outputting data to the screen. Universal models work only in one of the presented modes alternately. Digital devices are capable of simultaneously measuring signals and displays computational 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
The equipment is designed specifically for use in production and quite severe conditions. Fluke’s state-of-the-art oscilloscope features high performance and safety standards. The design is shockproof, with a maximum set of parameters. In addition, the device supports the multimeter function, registers the received data in the device memory, and it can be controlled without the help of hands.
Here are a few key parameters of Fluke oscilloscope models:
- Two or four channel.
- Frequency range: 60, 100, 200 and 500 MHz.
- Sampling rates up to 5 GS / s.
- Memory capacity: up to 10 thousand samples per channel.
- Recorder mode, recording up to 48 hours.
- An isolated port for connecting to a computer and other memory devices.
- The lithium-ion battery allows you to use the device for a long time and autonomously.
- Protected from dust and moisture.
- Security lock against unauthorized access.
This is the best instrument for engineers and the solution to most problems in the repair of electronic equipment.
