Worldwide Spectrum Allocations Poster

The national and international spectrum usage has continued to undergo a constant cadence of change. These changes necessitate the need to continue to evolve your awareness of valuable spectrum allocation information. As evidenced recently in the U.S.: Analog TV has mostly gone quiet and replaced with Digital TV; the LORAN-C navigation system has been shut…

Characterization of Satellite Frequency Up-converters

This application note describes methods using an R&S®ZVA Network Analyzer, one or two R&S®SMB100A Signal Generators and an R&S®FSW Signal Analyzer to accurately measure all the key parameters of frequency converters with embedded local oscillator. A commercial satellite up-converter is used as a device under test example. 

DVB-S2 & DVB-S2X Signal Generation in K-Band and Analysis

The application note address test and measurement possibilities for DVB-S2 and DVB-S2X signals in the Ku & Ka -band. The AN includes detailed description of measurement setups, DVB-S2 and DVB-S2X signal generation, up-conversion and signal quality (Error Vector Magnitude and Modulation Error Ratio) analysis in the Ku & Ka-band using Rohde & Schwarz instruments.

Multicarrier group delay measurements using the R&S®FSW signal and spectrum analyzer

Demonstration of group delay measurements with the R&S®FSW signal and spectrum analyzer from Rohde & Schwarz. The R&S®FSW-K17 option performs group delay measurements – relative and absolute group delay – for example on amplifiers and frequency converting devices (mixers) over a wide analysis bandwidth using a multicarrier signal.

Group delay measurement on devices with an embedded LO using the R&S ZVA vector network analyzer

This video demonstrates group delay and relative phase measurements on frequency converting devices where access to the LO is limited. The measurements are made using the R&S ZVA vector network analyzer equipped with the R&S ZVA-K9 embedded LO mixer delay measurements option from Rohde & Schwarz. Based on a unique and novel two-tone method, mixers…
