AKTAKOM AWG-41XX series digital generators are capable of forming independent signals on two channels. The devices of this series use the latest methods of many signals generation and direct digital synthesis of arbitrary waveforms providing the high stability of the output frequency and high frequency and amplitude resolution. At the same time the price of such generators is very low. These AKTAKOM generators combine functions of various devices: digital sine wave generator, pulse generator of different forms, arbitrary waveform generator, digital frequency meter etc. All of these functions give us lots of advantages. Read about the functions of AKTAKOM generators and their use in the present article.

The article describes the basics of spectral analysis and the usage of the Tektronix MDO4000 built-in spectrum analyzer.

In May 2012 the Russian office of the Tektronix corporation sent the author of this article a MDO4000 oscilloscope for its test and evaluation capabilities. During the test over 560 waveforms, spectrums and spectrograms have been received. This article describes the most important features of the new oscilloscope.

Nowadays the generators of sinusoidal and pulse signals are widely used in various electronic, communication, radar, broadcasting and other devices. This article describes the use of digital spectrum analyzer for comprehensive testing and control of signal generators. As an example one of the most popular and relatively cheap digital spectrum analyzers AKTAKOM AKC-1301/1601 with the band frequencies from 9 kHz to 3/6 GHz is given.

This article is devoted to the newest means of wavelet signal analysis which haven’t been implemented yet in digital oscilloscopes hardware. These new means provide precise signal analysis and detection of hardly detectable signal characteristics. In MathLab these features are already applied in additional Wavelet Toolbox package and can be used in practice for actual oscillograms analysis. This article closes the theme started in the previous editions of our magazine.
