Easier Manipulation of Arbitrary Waveforms
Rigol Technologies USA Inc.’s DG1000Z Arbitrary Waveform
Generator with SiFi Technology creates a new class of instrument
for engineers who need to generate arbitrary waveforms. SiFi (signal
fidelity) technology makes it possible to reproduce waves with flexibility and convenience at a higher signal fidelity than traditional DDS
generators. Using SiFi technology, signal-to-noise is improved by 10
to 15 dB compared to DDS on the same waveform. Featuring a memory depth of 8 million points standard ( 16 million points optional)
and over 160 built-in arbitrary waves, the Rigol DG1000Z can generate high-fidelity signals with ease.

Updating the Tried-and-True
Arbitrary waveform function generators are primarily used in the
electronics industry in the design process, production and repair of
other electronic equipment. Standard functions such as sine waves,
square waves and pulses can be produced from the generator. Siglent
Technologies’ SDG5000 family has two independent generators in
one instrument. Other less-common waveforms, such as EKGs, earthquake (seismic) waveforms, complex algebraic and trigonometric
functions, as well as exponential ramps and stair step signals, can be
produced. The arbitrary waveform capability allows users to produce
and generate essentially any waveform they wish to produce.

Low-Noise, Real-Time Oscilloscope
Overcoming obstacles and challenges in oscilloscope technology development, Tektronix’s DPO70000SX 70-GHz Performance Oscilloscope
provides accurate characterization of high-speed signals enabled by
patented asynchronous time interleaving technology. Key features of the
oscilloscope include: low noise (70-GHz real-time signal capture using
patented ATI architecture); a compact 5 ¼-in instrument package; precise, scalable performance using an UltraSync multi-unit time synchronization bus; and high trigger performance with >25-GHz Edge trigger
bandwidth (with new Envelope trigger). Low-noise, high-fidelity signal
acquisition is critical in ultra-bandwidth applications, and is also needed
for high-energy physics research and other scientific applications.

Boosting the Real-time Sampling Rate
High-speed oscilloscopes are vital tools in the development of high-
speed digital networks, the critical backbone of the rapidly expanding
Cloud-based computing paradigm that characterizes the digital age.
Reaching 100-GHz bandwidth (the previous record was 65 GHz) is a
scientific achievement for commercial products. Teledyne LeCroy’s
LabMaster 10-100 Zi 100-GHz Oscilloscope features a 100-GHz
bandwidth and 240 GS/sec real-time sampling rate, and analyzes the
fastest phenomena found in R&D labs where engineers and scientists
are working on communications systems, high-bandwidth electrical
components and fundamental scientific research. At 240 GS/sec, sam-
ples are acquired at time intervals of 4. 17 psec, 50% faster than the
next-fastest digitizer, yielding excellent signal reconstruction.

Quieting Quantum Cascade Lasers
Quantum Cascade Lasers (QCLs) operate with high power at wavelengths suited to detecting molecules significant to humans. Electronic noise can dominate the laser output. Linewidth can broaden, power
can fluctuate and center wavelength can shift. All wreak havoc on the
detection threshold of a spectroscopy system. Wavelength Electronics Inc.’s QCL Laboratory Series QCL Driver drives current to QCLs
with extremely low electronic noise, enabling chemical sensor developers to narrow center wavelength linewidth, maintain a stable center
wavelength and improve signal-to-noise ratio by an order-of-magnitude. The instrument family is designed for easy operation by
researchers in a laboratory setting. Four current levels are offered: 500
mA, 1A, 1.5A and 2A, so researchers can minimize the noise for their

Implantable Telemetry for Animal Research
Data Sciences International (DSI)’s Physio Tel HD-XG is a fully
implantable telemetry device for use in research animals. It allows for
continuous, real-time monitoring of glucose directly in arterial blood.
The implant also continuously monitors body temperature and physical activity, and transmits second-to-second changes in physiology.
The HD-XG’s primary use is drug discovery and basic research related
to diabetes and other metabolic diseases. It is also relevant to other
research areas, including drug safety assessment.

Induced pluripotent stem cells (iPSCs) offer new opportunities in
research application. Researchers are using iPSCs for drug and toxicity screening, as well as for studying differentiation pathways and
modeling diseases. As the use of stem cells in research grows, there’s
a critical need for a reprogramming method that’s efficient and safe.
EMD Millipore Corp.’s Simplicon RNA Reprogramming Technology system uses a single synthetic, polycistronic self-replicating RNA
replicon efficiently engineered to mimic cellular RNA to generate
human iPSCs safely. With the technology, users can create integra-tion-free iPSCs using synthetic RNA, reprogram efficiently and easily
