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 and measurement uncertainty is reviewed.
This application note addresses system and manufacturing engineers. It focuses on CCR/CATR and TVAC RF tests of components and functional modules as well as complete satellite communication payloads at prelaunch level.
In this paper we will review the basics of spurious measurements and how the parameters used can affect the detection performance. A new technique as used in the R&S®FSW-K50 spurious measurement application which makes spurious search faster and easier to configure.
Demonstration of group delay measurements with the R&S®FSW signal and spectrum analyzer from Rohde & Schwarz. The R&S®FSW-K17 option performs group delay measurements – relative and absolute group delay – for example on amplifiers and frequency converting devices (mixers) over a wide analysis bandwidth using a multicarrier signal.
Noise Power Ratio (NPR) is an add-on tool for WinIQSI(TM) to generate noise power ratio stimulus signals and measure the resulting noise power ratio of a device under test (DUT) using Rohde & Schwarz instruments via LAN or GPIB bus.
This Application Note gives a short overview how signals with two different modulation schemes can be analyzed. The Application Note focuses on DVB-S2(X) signals, but the approach may be used for similar signals as well, as e.g. used in microwave backhaul links.
This application note describes methods using an R&S®ZVA Network Analyzer, one or two R&S®SMB100A Signal Generators and an R&S®FSW Signal Analyzer to accurately measure all the key parameters of frequency converters with embedded local oscillator. A commercial satellite up-converter is used as a device under test example.
This application note reviews a new calibration subsystem which consists of Inline Calibration Units (ICUs). These ICUs are designed for in situ use, so they are left in place both during the calibration procedure and during the measurement of the Device Under Test (DUT).
The application note address test and measurement possibilities for DVB-S2 and DVB-S2X signals in the Ku & Ka -band. The AN includes detailed description of measurement setups, DVB-S2 and DVB-S2X signal generation, up-conversion and signal quality (Error Vector Magnitude and Modulation Error Ratio) analysis in the Ku & Ka-band using Rohde & Schwarz instruments.
This video demonstrates group delay and relative phase measurements on frequency converting devices where access to the LO is limited. The measurements are made using the R&S ZVA vector network analyzer equipped with the R&S ZVA-K9 embedded LO mixer delay measurements option from Rohde & Schwarz. Based on a unique and novel two-tone method, mixers…
