Here’s a quick review of some basic instrumentation common to most engineering work benches. Ammeter The ammeter is the basis for many other electrical measuring instruments. Whether you are measuring volts or ohms, essentially inside the instrument you are measuring current. Measurement of current in a circuit is somewhat problematic because all the electrical energy […]

Measuring ESR and ESL of dc-link capacitors
Impedance analyzers work better than LCR meters when it comes to sizing up the super-low impedance and inductance of modern power converter capacitors. Tim Ashworth, Meng Li, Zurich Instruments DC-link capacitors are often found in power conversion applications such as inverters, motor drives, medical power supply equipment, and so forth. Consequently, dc-link capacitors often need […]
Overview of electrical measuring instruments, Part 3
In recent columns, we’ve given a quick review of some basic instrumentation common to most engineering work benches. Here are a few more instruments found in many engineering labs. Signal generator Signal Generator is a generic term describing various instruments, all sharing a single rationale, which is that a device under test (DUT) requires a […]
Overview of electrical measuring instruments -Part two
In a recent column, we gave a quick review of some basic instrumentation common to most engineering work benches. Here are a few more instruments found in many engineering labs. Curve Tracer The curve tracer is a member of the oscilloscope family of measuring instruments. In its CRT or flat screen display, the user sees […]
Network analyzer vs. spectrum analyzer: What is the difference?
By Lisa Clark Before we differentiate a spectrum analyzer and a network analyzer, it is important to understand what these two instruments are, and what function they perform. Thus, we give a basic overview of the two devices and their basic mechanism: Spectrum Analyzer The spectrum analyzer is an electronic device that is used for […]
