| + | =====Background===== | ||
| There are many times where you are interested in measuring the phase angle and magnitude difference between two signals (sine waves). In most Circuits classes, students calculate phase difference using an oscilloscope by measuring the time difference between the zero crossings of two signals. This process can be tedious and prone to errors. Measuring phase is part of teaching phasor notation. Students have trouble going back and forth between phasor notation and time signals, at least in the beginning. Students are exposed to the same sort of gain / phase information from a Bode plot but in a different form. | There are many times where you are interested in measuring the phase angle and magnitude difference between two signals (sine waves).

| - | There are specialized instruments for that, known as a Phase Analyzer. This is typically used in teaching power systems and power electronics circuits but general circuits classes can benefit as well. A new virtual instrument has been added to the ADALM1000 tool kit in ALICE 1.3. A phase analyzer shows the phase relationships between two or more sinusoids in the complex plane, on a polar plot. Many professors teaching introductory circuits courses find a tool like this useful when students are first learning about phasors. | + | There are specialized instruments for that, known as a Phase Analyzer.
