A network analyzer consists of a signal source and a receiver. The receiver will detect changes in the output signal of the device (or network) and then compare it to the source signal fed into the device. To evaluate the effect of the device on current and voltage, the VNA measures the resulting amplitude and phase response. This results in transmission and reflection measurements, impedance, and s-parameters from which test engineers can characterize their device under test.
A programmable DC power supply is connected to the device under test through wires connected to a DC power panel. Engineers can set voltage or current levels to power the device for testing. The DC power supply is a programmable DC power supply.
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...
View Full VersionThis article will detail the basics of a clamp meter and the principles of measurement. When it comes to instruments that measure current, many people may think of analog or digital multimeters. However, if you want to make measurements without breaking the circuit, a clamp meter is recommended. Direct wiring method ...
View Full VersionIn this article, we will describe the basic measurements of an impedance analyzer. Overview An impedance tester is an instrument used to measure AC resistance or impedance. This article will introduce the basic knowledge about impedance, the measurement method of impedance, and how to use the impedance tester. What is impedance? What is impedance? In short, it is "a quantity that indicates the difficulty of the flow of alternating current". ...
