Rare faults and intermittent signals are difficult to capture. The R&S®RTO Oscilloscope supports the acquisition and the detailed signal analysis of these signals by using the history mode. The history mode allows the user to look back to previous acquisitions and apply the wide set of analysis functions of the RTO. Furthermore it stores the accurate recoding time of the waveforms for subsequent analysis.

Frequency converters e.g. in satellite transponders need to be characterized not only in terms of amplitude transmission but also in terms of phase transmission or group delay, especially with the transition to digital modulation schemes. They often do not provide access to the internal local oscillators This application note describes a method using the R&S ZVA to measure group delay of mixers and frequency converters with an embedded local oscillator very accurately. The key aspect of this new technique is, that the network analyzer applies a 2-tone signal to the frequency converter. By measuring the phase differences between the two signals at the input and at the output, it calculates group delay and relative phase between output and input.

Rohde & Schwarz signal generators can be connected in various ways to system controllers (typically PCs) and external PC peripherals. Although most of these connection operations are also explained in the instrument manuals, it is not always easy to maintain an overview. Operating manuals commonly focus on explaining a dedicated feature of a single instrument. This application note examines a range of typical user tasks and how to solve them with the different instruments.

The measurement speed for spurious signal measurements is mainly defined by the spectrum analyzer sweep speed. With traditional swept spectrum analyzers and tight spurious limits the measurement can easily take hours or even a full day. This application note describes the differences in sweep speed between swept spectrum analyzers and modern spectrum analyzers with a wide-band FFT process, and how this improves the measurement speed for general spurious measurement.
