The Model PR-1 phase rotation meter identifies phase sequence on three-phase systems and indicates open or de-energized systems. It is used for installing rotating machinery and motors as well as for ...

Many RF systems, especially those related to the telecom market, need reference signals with accurate and stable frequencies. Single-chip PLLs (phase-lock loops), such as those that several IC ...

A fixed-frequency signal generator that can produce outputs simultaneously at multiple phases such as 45°, 90°, 135°, and 180° is sometimes needed for testing multi-channel analog-to-digital ...

In many situations, designers must control the phase of an output signal in order to make certain circuits work properly. At low frequencies, an op amp can be used to vary the phase. But as the ...
