Unlock the Power of Precision Measurements with Slotted Line Technology**
Slotted Line: An Essential Tool for Antenna and Transmission Line Measurements
A slotted line is a specialized transmission line equipped with a movable probe that allows for precise measurements of voltage, current, and impedance along the line. It is widely used in the telecommunications, aerospace, and research industries for antenna testing, transmission line characterization, and impedance matching.
Understanding the Slotted Line
The slotted line consists of a rigid or flexible metallic waveguide with a narrow slot cut along its length. A movable probe is inserted into the slot, and its position is precisely controlled to measure the electromagnetic field at different points along the line. The probe's position is typically indicated by a graduated scale or a digital readout.
