spectrum analyzerThe amplitude of an input signal can be measured versus frequency over the entire frequency range to determine the power of the signal. Spectrum analyzers are capable of performing tests such as noise figure and signal-to-noise ratio (SNR) to characterize the performance of a device and its contribution to overall system performance. For more information, please refer toApplication GuideFundamentals of Spectrum Analysis.
There 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...
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. ,,...
View Full VersionWe usually use time as a frame of reference, focusing on when certain specific events will occur. This includes electrical events. Oscilloscopes allow you to view the instantaneous value of a particular electrical event (or the voltage value of some other event converted by an appropriate transducer) over time. In other words, we can use an oscilloscope to view the waveform of a signal in the time domain. Fourier theory...
View Full VersionVector network analyzers measure a wide variety of devices and networks and offer a wide range of measurements for a variety of usage scenarios, such as spectrum analysis, pulse measurements, power amplifier (PA) characterization, and active device testing. The following guide describes how to set up a network analyzer for measurements, calibrate the measurement system, and interpret the measurement results: The uses of VANs are so wide-ranging that each measurement...
