White Papers

As technology evolves, choosing the best way to keep pace depends on the capability of your test assets. Keysight can help with Technology Refresh Services ranging from advisory consulting to equipment trade-ins. Explore the possibilities in our eBook: it describes ways to evaluate trade-offs and manage choices.

The wireless communication infrastructure must evolve to support growing user and data demands. See how service operators are investigating the use of mmWave technology to evaluate the best candidate frequencies for use in next gen 5G mobile applications.

Operation of modern telecom, navigation, control and measurement systems requires reference frequency sources. Their performance actually determines the systems’ main characteristics. Frequency stability vs. temperature, long-term and short-term stabilities, and phase noise are the most important for many applications.

Time Difference of Arrival (TDOA) is a technique for geo-locating RF sources. It requires three or more remote receivers (probes) capable of detecting the signal of interest. Each probe is synchronized in time to capture corresponding I/Q data blocks. Software shifts the time signature of each I/Q data set to find the difference in the arrival time at each probe.

Every leading-edge technology has to be measured using test equipment that goes even farther. While this has tremendous implications for calibration labs, the upside of upgrading often offsets the costs. Business Considerations of Equipment Refresh in a Calibration Laboratory identifies the factors that provide the biggest benefits.

At radar frequencies, 1GHz and above, asymptotic methods are usually preferred to calculate the radar cross section (RCS) of targets like aircraft, since the main parts of the target are more than an order of magnitude larger than the wavelength.  The challenge is how to combine these methods to compute the RCS.   In this white paper the two-step method that obtains accurate results in limited time is detailed.

This paper covers design choices of the world’s first K-band data converter. By avoiding established CMOS design principles and applying an ultra-high speed process, new capabilities emerged; a compact, single-core quantizer and design expertise led to breakthrough performance and layout and circuit simplifications are dominant design considerations.

In this technical white paper, read how to control the costs of test and ownership of your highly valued test and measurement assets. We offer an in-depth view of maintenance and calibration and offer tips to help you adopt technology faster and lower your cost of test.

In 2015 Entegra Solutions were contacted by Thales Air Traffic Management looking for the highest dynamic range, wide bandwidth data acquisiion card available. Their objective was to build a passive radar using beamforming techniquest to receive reflections of DVB-T Tv signals from aircraft to replace traditional airfield radars.

In 5G, the use of massive MIMO is a revolutionary idea. It has major implications for development and implementation within the 5G ecosystem. It also affects the set of tools you'll need to characterize and validate these highly complex systems.
