Abstract: Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line ...

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 ...

Co-sponsored by Analog Devices and Richardson RFPD. This webcast will provide a step-by-step approach to designing RF power and return loss measurement systems. The webcast will focus on a number of ...

Knowing the directivity specification of your measurement device can go a long way in setting measurement expectations. Directional power measurements are important when determining transmitter output ...

If you are involved in any sort of radio transmission, you probably have at least heard of SWR or standing wave ratio. Most transmitters can measure it these days and most ham radio operators have ...
