SC16-bit HD mode now standard for
Rohde & Schwarz RTE, RTO and RTP ’scopes
Starting immediately, all Rohde & Schwarz
RTO and R&S RTP oscilloscopes are delivered
with the high definition mode featuring 16-bit
vertical resolution. Users benefit from more
measurement performance at the same price.
Higher-resolution waveforms enable more pre-
cise analysis of signal details that would other-
wise be hidden by noise.
The high definition mode increases the ver-
tical resolution up to 16-bit.
In power electronics, it is frequently the
smallest details of a signal that are of interest,
also for high amplitude signals, ie, when char-
acterising switching power supplies. A high
vertical resolution is necessary to measure
small details of a signal with an amplitude up
to several hundred volts.
Rohde & Schwarz oscilloscopes accomplish
this with a hardware lowpass filter that filters
the signal after the A/D converter. The filter re-
duces the noise power, effectively increasing
the signal-to-noise ratio and increases the
resolution up to 16-bit.
The bandwidth of the lowpass filter can
be variably adjusted from 10kHz to a maxi-
mum of 2GHz to match the characteristics
of the applied signal. The lower the filter
bandwidth, the more the signal-to-noise ra-
tio is improved. Waveforms are displayed in
a higher resolution, showing signal details
that would otherwise be hidden by noise.
Thanks to the low-noise frontend and
highly accurate single-core A/D converter,
Rohde & Schwarz oscilloscopes have an
excellent dynamic range and measurement
accuracy.
Since hardware lowpass filtering takes
place in real time, acquisition and process-
ing rates remain high and the measurement
results are available quickly. All analysis
tools, including automatic measurements,
FFT and the history mode, can be used in
high definition mode.
High definition mode makes even the
smallest signal details visible. The highly
sensitive Rohde & Schwarz digital trigger
system allows users to easily isolate these
details and investigate them in greater detail.Each of the up to 16-bit samples is checked
against the trigger conditions and can initi-
ate a trigger. This means the oscilloscopes
are able to trigger on even the smallest sig-
nal amplitudes.
There are no unexpected aliasing effects
in high definition mode. Since high defini-
tion mode is not based on decimation, the
increase in resolution is not accompanied
by a reduction in the sampling rate. When
high definition mode is switched on, the full
sampling rate can be used, ensuring the best
possible time resolution.Contact:

laboration with Molex has a fasci-
nating new eBook, “Welcoming the
Connected Home”.
In the new eBook, subject matter
experts examine upcoming and fu-
ture trends in home automation and
strategies for designing Internet of
Things (IoT)-enabled devices, as well as specific smart home solu-
tions from Molex.
From connected devices like light bulbs and appliances to secu-
rity systems and home assistants, the smart home is allowing resi-
dents to interact with and program their living spaces to predict and
react to their needs.
The new eBook covers topics related to the connected home, ex-
ploring both current strategies as well as future possibilities. It in-
cludes tips on how to connect devices to the IoT, an exploration
of upcoming capabilities in intelligent integration, and a survey of
Molex products designed to serve specific smart home applications.
Molex products help engineers design intelligent and integrated
smart home systems which support a wide range of home automa-
tion applications including antennas, wire-to-wire connectors, ca-
ble assemblies, capaci-
tive switches, LED dis-
plays, and USB type-C
connectors.New eBook from Mouser and Molex

forefront of
groundbreaking
solar research
Scientists at The Aust-
ralian National University (ANU) have made a fresh series
of breakthroughs that could help further revolutionise solar
technology – making it more efficient, and more accessible –
following major discoveries last year.
The team from ANU have been concentrating on the solar
cell’s skin layer, which is 1000 times thinner than a human
hair, and is used to conduct electricity and protect the solar
cell. Previously, much of the research in this field has focused
on improving the body of the cells.
Lead researcher Dr Hieu Nguyen said when hydrogen atoms
are injected into a solar cell’s skin, rather than the cell body,
the performance of the entire structure is boosted significantly.
The ANU researchers initially discovered the skin layer can
emit light with some very distinct qualities.
They quickly realised the presence of hydrogen atoms dra-
matically changes
the characteristics of
this light – informa-
tion that can then be
used to understand
what’s going on in-
side the skin.
