A DC power supply provides a constant bias voltage or current to an electrical device, component, or circuit to ensure that the device under test operates as intended.
There are two main types of spectrum analyzers: sweep tuning analyzers and real-time analyzers. Modern spectrum analyzers use digital signal processing to provide more measurement capabilities, making it easier for you to interpret your measurements. Whether it's a swept-tuning analyzer or a real-time spectrum analyzer, they both display the change in amplitude with frequency. However, exactly how each analyzer handles...
View Full VersionA benchtop DC power supply is a power supply that is mounted to an engineer's workbench for use. It usually has a large, legible display and user interface to allow the engineer to easily achieve full control of the power supply from the front panel. Users can also control modern benchtop power supplies through software. In addition, engineers can easily access the output terminals from the front. Variable bench power supplies are a convenient electric...
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...
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...
