Real-time spectrum analyzers can collect data in the time domain and then convert it to the frequency domain using the Fast Fourier Transform (FFT). Real-time spectrum analyzers can quickly capture transient and fast signals.
How do I measure voltage? If you use a multimeter, anyone can measure it easily ■ Summary Since voltage is not visible to the naked eye, it is not possible to confirm "how much voltage is flowing through a circuit at a glance". However, the circuits of electronic devices have a set voltage for normal operation, and if the voltage is too high, it may lead to product malfunction or personal injury. In addition, ...
View Full VersionMost handheld or benchtop digital multimeters display measurements digitally. The number of digits displayed on the screen usually represents the measurement resolution of the digital multimeter. Resolution is the smallest detail that a digital multimeter can quantitatively determine when making a measurement. Therefore, the more digits a digital multimeter displays, the higher its resolution. Handheld digital multimeters are typically capable of displaying three-and-a-half and four...
View Full VersionTo connect two DC power supplies in series, connect the positive terminal of the first power supply to the negative terminal of the second power supply to form a "daisy-chain" connection, where the series voltage is the sum of the voltages of the two power supplies. To connect two DC power supplies in series, proceed as follows: Note that the voltage of the load should be equal to or higher than the sum of the voltages of the two power supplies to prevent damage to the load or power supply. In addition, the load's rated...
View Full VersionAll modern oscilloscopes are digital storage oscilloscopes (DSOs) that use digital signal processing to capture and display analog signals. If the oscilloscope has the ability to observe these signals simultaneously in the digital domain, it is a mixed-signal oscilloscope (MSO). If the oscilloscope has a built-in spectrum analyzer function, it is a mixed-domain oscilloscope (MDO), although this term is less common. ,,...
