Expanded signal analysis capabilities using modern digital oscilloscopes
Issue: KIPiS 2020 #5
The article describes the expanded
signal analysis capabilities based on measurements with postprocessing implemented using hardware and software options of
modern digital oscilloscopes. There is also
prerequisite analysis made for the development of such options, as well as their classification introduction. The present article
will inform you of the whole range of
practical tasks that can be solved with the
options functional capabilities of R&S
RTO and R&S RTP series oscilloscopes as
one of the most advanced measuring instruments in the market.

Measurements of some EMC characteristics when testing the transceiver modules
Issue: KIPiS 2020 #4
In the present article based on the
purpose analysis of the transceiver modules
and their typical structural diagram
the authors have identified the typical
EMC problems for which characteristics
they may use the typical indicators. Basing
on the operating modes of the transceiver
modules, which corresponds to the
highest noise emission and the lowest
noise immunity, the authors suggest the
general schemes for measuring the above
EMC indicators using Rohde & Schwarz
solutions and consider the key points in
terms of preparation for such measurements.

Pulsed phase noise measurements with R&S FSWP phase noise analyzer
Issue: KIPiS 2020 #3
The current article describes the issues
of the phase noise measurements of
pulsed modulation signals that are widely
used in radio detection and location. The
authors analyze the spectral features of
such signals and theoretical limitations
determined by the pulse operation mode;
estimate the dependence of the noise parameters
on the modulating pulses characteristics;
consider the digital phase demodulation
method with cross-correlation
processing; describe the functional features
of R&S FSWP analyzers. Also they
describe the principle and example of
pulse-modulated carrier signal processing
in R&S FSWP analyzer as well as the
example of measuring the amplitude and
phase stability of pulsed-modulated signals.

State-of-the-art capabilities of jitter analysis in high-speed digital devices using R&S RTO-K12 option
Issue: KIPiS 2019 #2
The present article demonstrates the
state-of-the-art capabilities of jitter analysis
in high-speed digital devices by the
example of R&S RTO-K12 option. The
author suggests analyzing the reasons
that may cause jitter, classification of its
components and the main approaches to
its reduction, as well as the typical consequences
of this phenomenon appearance
when operating digital devices. This article
also demonstrates the existing methods
of jitter analysis and shows examples
of measurements using R&S RTO-K12
option to estimate temporal and statistical
characteristics of digital signal jitter.

Radio interference search and analysis by using R&S FSH handheld spectrum analyzer
Issue: KIPiS 2015 #5
In the present article they consider the question of spectrum analyzers use when solving electromagnetic compatibility problem. Here you will find the analysis of the main tasks in the field of EMC and also read about the advantages of handheld spectrum analyzers comparing to the nonportable laboratory devices. In this article R&S FSH series spectrum analyzers are compared to the initial and average level devices which may help you to see the way they can replace each other when solving the described tasks.
