and resolution bandwidth. Using the per-
sistence mode, rapid signal changes, sporadic
signal interference and weak superimposed
signals can easily be made visible. The abil-
ity to overlap FFT frames enables the oscil-
loscope to detect intermittent signals such as
pulsed interferers. This powerful FFT func-
tion plus the high dynamic range and input
sensitivity of 1 mV/div make the R&S RTE
ideal for tasks such as EMI debugging of elec-
tronic circuits during product development.
Thanks to the high-resolution 10.4
″
XGA
touchscreen, users can intuitively perform
their daily T&M tasks. For example, users can
simply “drag & drop” waveforms to arrange
them on the screen. The screen can flexibly be
divided into several diagrams according to the
user’s requirements. Realtime miniature views
of the signals on the edge of the screen allow
users to always see what is happening. The
R&S RTE controls are color-coded and indi-
cate which channel is currently active. The
color coding corresponds to the signal dis-
play on the screen. Dialog boxes are opened
as semi-transparent overlays over the active
waveforms, which maintain their full size.
Users can adjust the transparency of dialog
boxes as required. Signal flow diagrams and
forward and back buttons in the dialog boxes
simplify navigation. The configurable toolbar
provides fast access to frequently used func-
tions. Users simply select a tool and apply it
to their waveform. Tools that have a simi-
lar function are grouped together. In addition
to the standard tool suite, the R&S RTE fea-
tures many highlights such as fingertip zoom,
which allows users to quickly view signal
details by moving their finger or mouse along
the signal. Another example is the SaveSet
tool which enables users to quickly load dif-
ferent configurations. To select the right con-
figuration, the user simply swipes a screenshot.
In addition to the standard functionality, the
oscilloscope offers various optional applica-
tion solutions, including trigger and decoding
options for serial buses (such as I2C, SPI and
CAN) and a power analysis option. The logic
analysis capability offered by the R&S RTE is
essential for analyzing digital components of
embedded designs. The R&S RTE-B1 mixed
signal option can be added to any base unit
and offers 16 additional digital channels with
a sampling rate of 5 Gsample/s and a memory
depth of 100 Msample per channel. It is possi-
ble to decode up to four serial or parallel buses
simultaneously.
A comprehensive portfolio of high-qual-
ity active and passive probes is available for
the R&S RTE to perform measurements in
common voltage and current ranges. One
of the highlights of the active probes from
Rohde & Schwarz is a micro button on the
probe tip. This button can be used to perform
a variety of functions such as run/stop, autoset
and adjust offset on the oscilloscope. The
highly precise R&S ProbeMeter DC voltmeter
(measurement error: ±0.1%) is integrated into
the active probe and provides a convenient
means of answering questions such as “Is the
supply voltage correct?“ and “Is DC voltage
superimposed?”

two or four channels and a bandwidth of
200 MHz, 350 MHz, 500 MHz or 1 GHz.

Lauterbach: TRACE32 tool qualifi-
cation support-kit for code coverage
Lauterbach has announced a Tool Qualification
Support-Kit for the TRACE32 code coverage
analysis. This qualification toolkit was designed
to help customers facing the many challenges
of software development for safety-related sys-
tems to complement the tool qualification when
TRACE32 is selected as preferred solution for
trace-based code coverage analysis. It aims to
meet the requirements for the development of
avionic and automotive applications in compli-
ance with DO-178C and ISO 26262.
