Application of Spectrum Analyzer in Mobile Satellite Communication

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. Signal modulation can be divided into analog modulation and digital modulation, of which analog modulation, such as amplitude modulation (AM) and frequency modulation (FM) is most commonly used in broadcast communications, and digital modulation is based on two states, allowing the signal to represent binary data.In many tests,we usually use Arbitrary Waveform Generators and other test instruments.We can also supply China Digital Multimeters.Welcome all your questions.
