Nowadays, many arbitrary waveform generators can provide frequency sweep function, basically linear sweep and logarithmic sweep can be realized. Linear sweep means the output frequency changes in constant way of some Hz per second.

Phase noise refers to the random changes in the phase of the system output signal caused by various noises in the system (such as various RF devices).

TFG3900A as a dual channels function/arbitrary waveform generator, can generate a maximum 160MHz signal to meet the engineer’s measuring requirement. It can be operated not only by front panel, but also by remote interface: USB Host and USB Device, LAN.

In order to keep the harmonic content and waveform distortion rate in the power supply system within the specified values, it is necessary to know the actual harmonic content in the grid, which can be calculated by theoretical analysis and actual measurement.

Spectrum analyzer is a more suitable instrument for measuring EMI. Spectrum analyzer is the instrument displaying voltage amplitude change with the frequency and its waveform called spectrum.

Active power is the power to make the machine working, in another word, the electric power to transfer electric energy to other mode energy, such as mechanical energy, optical energy, heat energy, etc.
