This application note describes a software application that can be utilized in conjunction with Rohde&Schwarz Signal- and Spectrum Analyzers and Signal Source Analyzers to capture and analyze transient signals. The software application takes advantage of the instrument’s IQ memory buffer of up to 705 Msamples to capture and analyze IQ signals in the time domain and / or frequency domain. This is useful for measuring lock time, analyzing radar pulses, finding spurious transients, and other measurements similar in nature to these. This application can be used with R&S®Signal Source Analyzer FSUP and R&S®Signal and Spectrum Analyzers FSQ, FSU, FSG, FSV.

Receiver diversity improves reception quality by using multiple antennas with a preferably low correlation factor between each other. This results in a more robust handling of multipath signals, since a deep fade will then not affect all received signals at the same time. However, the compact dimensions of handheld devices can introduce unwanted correlation due to their dense antenna spacing. In this case, the popular diversity test setup consisting of several independent transmitters will no longer serve the needs of a realistic simulation, since correlation effects have to be taken into account here. A clever solution is to operate the R&S®SFU in split-fading mode in combination with a second transmitter. This can be another R&S®SFU, the R&S®SFE, the R&S®SFE100 or the R&S®SMU200A. In this way, two diversity signals of adjustable correlation for any common broadcast standard are coded in realtime, while their individual multipath profile is precisely specified by the extensive features of the R&S®SFU fader module.

Determining the noise figure of a component can be difficult in unshielded lab environments. Measuring small noise figures (less than 3 dB) and reproducing the results is sometimes not possible. These difficulties are caused by interference effects (electric fields) that can occur in any environment. A suitable remedy is a measurement environment able to shield the Device Under Test (DUT) against all interfering fields in the range up to 3 GHz. When used in conjunction with a spectrum analyzer and Noise Measurement Software FS-K3, the Shielded Box ZA-SB10 provides a complete noise measurement system.
