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 focuses on fully automated, fast and accurate measurements, of linear FMCW radar signals. It explains the basic signal processing, the impact on radar key performance indicators in case of linearity deviations and explains test and measurement of linear FMCW signals in detail.
This Rohde & Schwarz application note and associated application software may be used to conduct psychoacoustic speech quality evaluation for Voice over LTE (VoLTE) connections. The measurements are based on recommendations ITU-T P.862 and ITU-T P.863, respectively. The R&S CMWrun Software Sequencer Tool example sequences perform decoder / encoder calibration, connection setup for the UE under test and subsequent speech quality analysis under IP impairment conditions.
Channel Operating Margin, COM, is a single measure of channel performance with high data rates that includes the effects of signal impairments and the techniques used to compensate for those impairments. COM measures the performance margin of an interconnect, and can also be used to examine the interoperability margin of a high speed serial system. The derivation of COM itself can offer insights into the strengths and weaknesses of a design due to the inclusion of the ISI (inter-symbol interference) calculation that remains after equalization and the effects of noise, jitter, and crosstalk.
The 7000 series phase noise measurement system is designed to measure absolute and residual (additive) phase noise of active or passive devices. This app note explains how to use 7000 series signal source analyzers to measure the absolute or residual phase noise of pulsed signals in amplifiers.

Rohde & Schwarz introduces the R&S Scope Rider as the first handheld, portable oscilloscope with the functionality and feel of a state-of-the-art lab instrument. This device combines five instrument functions into a compact rugged design, making it perfect for mobile installation and maintenance applications in both the lab and the field. The Scope Rider can also function as a logic analyzer with eight additional digital channels, as a protocol analyzer with trigger and decoding capability, as a data logger and a digital multi-meter.
The R&S ESU from Rohde & Schwarz is a new family of CISPR16-1-1-compliant EMI test receivers that meet all civil and military standards for electromagnetic interference measurements. New FFT-based test methods speed up the measurement. With the time-domain scan, users can perform overview measurements up to 100 faster than on previous EMI test receivers. The instrument also features comprehensive test functions such as a complete set of parallel detectors including the new CISPR-RMS detector, RF scan, IF analysis and numerous report functions. The R&S ESU is available in three models with the frequency ranges 20 Hz to 8 GHz, 26.5 GHz and 40 GHz.
These RF Synthesizer/VCO models are ideal for applications involving satellite communications, cellular repeaters, remote radio heads, WiMax/LTE Infrastructure, point-to-point radios, broadband CATV, diversity receivers, software defined radios, and more.
