Especially with test receivers not comprising a built-in disk drive (ESHS10, ESVS10, ESVD, ESVB and ESPC) it is necessary to store instrument settings before a firmware update or before changing the battery of the static memory to be able to restore the settings later on. Frequently it is desirable to exchange settings or comprehensive data like transducer sets between receivers, or receivers have to be set up to suit different applications.

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.

The R&S EX-IQ-Box serves as a digital baseband interface between a device under test (DUT) and Rohde & Schwarz generators, analyzers and radio communication testers. The DigIConf software supplied with the device controls up to four R&S EX-IQ-Boxes in a test setup and can thus output IQ data for feeding into a DUT while simultaneously receiving IQ output from a DUT.To work together smoothly, the DUT, the R&S EX-IQ-Box and the R&S test instruments have to be configured properly. The purpose of Application Note 1MA168 is to introduce the right 'initial steps' required to get started successfully.

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.
