Antennas are a popular topic among radio enthusiasts. The Rigol Spectrum Analyzer VB1020 option and utility kit are good tools to help improve antenna design and characterization. This combination ...

Voltage Standing Wave Ratio (VSWR) is a measurement of the impedance match of any RF component, subassembly, instrument in reference to a standard 50-Ohm resistive impedance. It is generally expressed ...

StarLab is a near-field multi-sample system with spherical geometry. Antenna radiation patterns in the far field are obtained indirectly by sampling the field near the antenna. The sampled near field ...

The Morehead State University Space Science Center anechoic chambers are experimental laboratories that simulate the electromagnetic environment of space to allow testing and measurement of satellite ...

Rohde & Schwarz offers a temperature option for its mobile antenna measuring chamber. It can be used to characterize specimens at -20 °C to +85 °C. The temperature option is offered for the mobile R&S ...

If you have ever operated any sort of transmitting equipment, you’ve probably heard about matching an antenna to the transmitter and using the right co-ax cable. Having everything match — for example, ...

The current status of the CE Marking has increased the economic pressure on product manufacturers and test houses to optimize their test procedures for radiated emissions, focusing on 30 to 1,000 MHz.

Here’s a situation that creates fear and trembling: The engineer receives a call from the radio station: “The transmitter is off the air and there is a VSWR fault.” If the station is fortunate, the ...
