We know that the spectrum is the most important resource for wireless communications. The spectrum is short for frequency spectral density and is the frequency distribution curve. The distribution curve is tested by the spectrum analyzer, which can not be seen by the naked eye.

Many test instruments are common to see in our life,such as Spectrum Analyzer.In the meantime,do you know how to choose the Digital multimeters

The important role of signal generator - Signal Modulation: Signal modulation refers to the modulated signal, the amplitude, phase or frequency changes to embed low-frequency information into the carrier signal at high frequency, the signal we got can be transmitted from voice to data, to Video any signal

As we all know that the Power Analyzer has a widely use range in test.Similarly Function Generators are important too.But the Mobile Satellite Communication is more and more important.Let's know about it.

There are many ways to measure frequency, as we all know the comment to see is Universal Frequency Counter.According to its working principle is divided into passive frequency measurement, comparison method, oscilloscope method and counting method.
