交流（AC）是一种极性周期性地反转并且幅度随时间不断变化的电流。 与直流（DC）电相比，交流电的发电和输电成本更低，效率更高，因此企业和住宅通常使用交流电。 在传输过程中，变压器可以通过提高或降低交流线路的电压，降低功率损耗。
交流电是一种家用电能——当消费者将电视等家用电器和其他器件的电源插头插入墙壁上的插座时，便能使用交流电。交流电可以转换为直流电，供几乎所有电子器件使用。
Network analyzers perform component characterization tests. A network analyzer provides a calibrated excitation signal to an RF network or device under test (DUT) and measures the vector response at frequency with phase and amplitude information. A VNA provides transmission (transmission coefficient, insertion loss, gain), reflection (reflection coefficient, VSWR, return loss), and impedance measurements, as well as s...
View Full VersionIf you want to measure current, voltage, etc., you need specialized measuring equipment. Analog and digital multimeters are usually used to measure current, but the circuit must be cut off and the multimeter and the circuit connected in series in order to make the measurement. However, it is not uncommon that it is not possible to disconnect the circuit in some cases. In addition, there is a danger of electric shock when the circuit is disconnected. In this case the clamp meter...
View Full VersionA signal that looks very complex in the time domain behaves quite differently in the frequency domain. Time domain measurements show an impure sine wave. Without frequency domain measurements, it is still impossible to know the source and frequency of the second harmonic. Spectral analysis can show the spectral components individually, thus revealing the source of the interference. The information provided in the time domain (e.g., the signal pulse on...
View Full VersionMany people use digital multimeters to easily measure current, voltage, resistance, etc. However, there is a drawback to using a digital multimeter to measure current, namely: the circuit must be disconnected and the digital multimeter must be connected in series with the circuit under test in order to make the measurement. In this case, a current probe can be used instead of a digital multimeter to make measurements. Since the electrical connection of the circuit is no longer required, the current probe is more time-consuming...
