Beijing, October 30, 2020-When it comes to electronic measurement, the first thing you think of is an oscilloscope or logic analyzer. However, these tools are only used when collecting certain signals, and these signals are usually not available and need to be loaded externally.
For example, the strain gauge amplifier itself does not generate a signal, but only amplifies the power of the signal received in the sensor. This requires testing the amplifier before connecting it to the circuit for its input signal, and an excitation signal must be provided at the input. When engineers characterize a new design, they need to perform margin testing or limit testing to ensure that the new hardware meets the design specifications within and outside the entire range of working conditions. This requires a complete solution that can generate signals and be able to Take measurements.
The signal generator is used in conjunction with an oscilloscope or spectrum analyzer to form a complete measurement solution. In various configurations, the signal generator can provide excitation signals in the form of analog waveforms, pulse patterns, modulation, distortion, and noise. For effective design measurement, characterization measurement or debugging measurement, it is very important to consider both elements of this solution.
Tektronix collected and investigated the common functions of Tektronix arbitrary/waveform function generators used by engineers around the world. The results showed that more than 60% of engineers only used 14.2% of its functions. How to make full use of Tektronix’s arbitrary waveform function generator to meet your testing needs and make it worthwhile? Tektronix engineers have compiled 25 typical application scenarios in 7 major directions to help you speed up debugging efficiency.

Arbitrary Waveform/Function Generator (AFG) can generate various excitations, and is also a popular signal generator architecture in the industry. If the DUT requires typical sine and square waves (and so on) and can switch between the two frequencies almost instantaneously, the arbitrary waveform/function generator (AFG) is the choice. AFG provides many unique advantages: it provides stable standard waveforms, such as sine waves, square waves, pulse waves, triangle waves, and so on. In addition, users can generate so-called arbitrary waveforms and have user-defined waveforms. Moreover, AFG provides a method to modulate signals from internal or external sources, generate sweep frequencies, and output pulse signals.
