Digital developers can use AWG to generate test signals to provide excitation to a device under test (DUT) and use an oscilloscope to analyze the device's operating status.
In-phase quadrature modulation (IQ modulation) is the main modulation scheme used in communication applications. It is popular because of its efficient use of bandwidth, meeting the increasingly urgent need for bandwidth in a world where data volumes are growing exponentially. It is important to test with simulated IQ signals because designers are always faced with a lack of bandwidth in an interference-ridden spectrum. Example...
View Full VersionIts advantages include: Ultra-low jitterTrueform function/arbitrary waveform generators have jitter as low as 1 ps and excellent edge stability. You can even use them as system clocks for timing and triggering other instruments. Thanks to better jitter performance, you can locate edges more accurately, which helps reduce timing errors in circuit design. Ultra-low...
View Full VersionWhat is resistance in electricity? This article will cover the basics of resistance, how to calculate resistance, and resistors. Many people have heard the word "resistance" when they were students, but may still not understand it. However, because they don't understand it, they are hesitant to ask people about it now. Simply put, resistance is a force that flows in the opposite direction of the current. Resistance...
View Full VersionThere are several ways to test a DC power supply, here we only introduce a few common methods. Conductivity test: You can use the multimeter's conductivity mode to accomplish this test. Touch the positive and negative terminals of the power supply with the multimeter pen. If it is on, the multimeter will beep. This test is designed to determine if the power supply is delivering power and if there are any breaks in the wiring. Voltage...
