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.

This application note describes in detail the steps required to make a noise figure measurement on a spectrum analyzer using the “Y Factor” technique. Background equations are presented for each step of the calculation. In addition, guidelines are provided to ensure a repeatable measurement. Measurement uncertainty is then reviewed, including contributions due to the noise source, analyzer, and the DUT itself. Finally, a software utility is presented that automates the noise figure calculation using four measurements from a spectrum analyzer. The utility checks the measurement guidelines and highlights potential problem areas. It then calculates the noise figure for the DUT along with the measurement uncertainty.

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.

Automating measurement setups is advantageous for multiple reasons. It saves time in case of repeated measurements and in hazardous environments, instruments can be operated from a distance. The measurements are repeatable because they are always performed with a defined procedure, leading to higher test confidence.But in remote control applications, users often perceive synchronization and binary transfers as challenging. Therefore, this application note focuses on binary transfer of data to and from the instrument and shows code example to demonstrate the ease of use.
