The voltage standing wave ratio (VSWR) is one of the parameters in RF systems that measures the impedance mismatch. Under ideal conditions, when the load is perfectly matched to the source, the VSWR will be 1. A mismatch in the system causes reflections that will increase the VSWR and lead to losses in transmission. Although most RF components are typically designed and specified with a characteristic impedance of 50 Ω , applications and system components for cable television are designed and specified with a characteristic impedance of 75 Ω . This application note describes the measurement procedure for VSWR measurements in 75 Ω systems using the R&S®FSH3-TV handheld TV analyzer.

Vector Network Analyzers (VNA) are gaining popularity in the Signal Integrity community as time domain measurement and analysis tools. VNAs with 8 ports or more can provide significant decreases in test time by migrating from a 4-port measurement system to an 8-port measurement system. For tight tolerance DUTs that are barely within the test limit lines, small increases in accuracy can be realized by testing all of the test parameters at once, because the entire test setup is at the same temperature. This application note discusses the thermal advantages of testing an 8-port DUT with the R&S ZNBT VNA. The use of the ZNBT to assess and debug two differential pairs in a 20-inch backplane is presented.

Noise-Power-Ratio (NPR) measurements are a common procedure and a simple but useful tool to characterize the performance of power amplifiers for satellites or other multi-channel communication systems. The main advantage is the use of wideband signals like noise, multi-carrier CW tones or I/Q modulated signals, which leads to a better simulation of the real environment. This application note provides information how to generate these signals with a vector signal generator and perform NPR measurements with spectrum analyzers. With the R&S®SMW200A vector signal generator any desired test signal can be created. The R&S®FSW spectrum and signal analyzer offers an automated function for NPR measurements.
