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 […]

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 […]
