The Loop-Powered Transmitter (LPT) joins the more than 20 loop-powered devices—from digital panel meters to controllers—made by Otek Corp. The LPT uses a patent-pending technique, along with ...
Editor's Note: This is a multi-part excerpt from Agilent Technologies' Application Note: Mobile WiMAX PHY Layer (RF) Operation and Measurement. Part 1 of this article introduces the WiMAX standard and ...
This reference design shows how to develop a high-performance, high-voltage 2- or 3-wire 4–20mA current-loop transmitter suitable for industrial process control and ...
Galvanically (that is, optically or electromagnetically) isolated 4- to 20-mA current loops offer robust noise immunity and tolerate long cable runs. These advantages, combined with simple unshielded ...
