If you have ever read advanced textbooks or papers about electronics, you may have been surprised to see the use of complex numbers used in the analysis of AC circuits. A complex number has two parts: ...

Offered in DC and AC/DC versions, the MeasureReady 155 from Lake Shore Cryotronics serves as a low-noise source of current or voltage in the lab. The 155 performs precision DC I-V and C-V curve ...

Overvoltage protection of AC power lines is a common practice, which encompasses a variety of protection circuit solutions. Most designs are cost-driven and tend to use only the bare minimum of ...

Programmable AC power sources have been widely used to implement and support numerous product test procedures over the years. They provide the test engineer with the ability to fully control voltage, ...
