A DC power supply converts alternating current (AC) electricity to DC electricity either by a linear method or by a switching method. Switching power supplies are more efficient, lighter in weight and smaller in form factor. Linear power supplies can achieve lower noise, but this is no longer an advantage with modern switching power supplies.
Signal analyzers are capable of measuring the amplitude and phase of an input signal at a single frequency. The Signal Analyzer combines the large dynamic range of a swept-tuned spectrum analyzer with the power of a Vector Signal Analyzer (VSA) to perform in-channel measurements, such as Error Vector Magnitude (EVM) measurements, which require both magnitude and phase information. The VSAs are available in a wide range of sizes and sizes.
View Full VersionWant to know how to use the current probe? Please first understand the following basic usage of the current probe and precautions for use. Since electricity is invisible, it is not possible to immediately determine whether a malfunction has occurred. In some cases, current measurements are required on a daily basis to prevent malfunctions, as well as to identify the cause of malfunctions when they do occur. Digital multimeters, clamp meters, and current probes can be used...
View Full VersionWaveform sequencing lets you create multiple configured waveforms that contain multiple common segments. Sorting lets you build complex, long waveforms using as little instrument memory as possible. Waveform sequencing lets you save storage capacity by replaying shorter waveforms at different locations on the signal as needed. Many tests require long waveform memory records. The required record length...
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...
