With relatively few progressions in conventional optical microscopy during the past decade, pushing through the physical limitations of these systems has proven to be challenging. Despite this stand-still, engineers have recently been able to develop solutions to some of the limitations in modern microanalysis. Using an integrated design approach, digital microscopes have been developed to overcome many of the shortcomings of conventional optical microscopes. Specifically, in regard to ceramics, one of the major difficulties in observing and analyzing these materials is the complete lack of contrast typically associated with them, especially when viewed through a traditional optical microscope. However, by using the advanced features of fully-integrated digital microscopes, coupled with highresolution zoom lenses and digital camera technology, users can now image samples that were previously relegated to the realm of an SEM.

Management systems are sometimes misunderstood as nothing more than a heavy administrative burden providing limited business benefit. Many organizations with management systems in place have not effectively defined the processes, and have not put the required measurements in place. Perhaps it is because they think "ISO 9001 is separate from how we run the business," and limit their management system to simple checklists and work instructions. By maintaining these beliefs, organizations are missing out on significant opportunity. Increasingly, customers and stakeholders are not satisfied with basic compliance – they are looking for less reliance on procedures, and more focus on risk management.

The process approach to auditing means shifting focus away from basic compliance to embrace an "improvement" mindset. When activities and related resources are managed as a process, the desired results can be achieved more efficiently.

An ideal signal has no phase noise, harmonics nor spurious frequency components associated with it.
Unfortunately the ideal signal does not exist in the real world, and these factors degrade the spectral
purity of all real world signals to some degree. High‐performance microwave signal generators are
designed to maximize spectral purity, with very low levels of phase noise, harmonics and spurs, while
maintaining general purpose flexibility. The levels of spectral purity performance are one of the key
differences between high‐performance, mid‐range and low‐end or entry‐level signal generators. This
paper discusses the factors that make up spectral purity specifications to help you make more informed
comparisons of microwave signal generator performance for test and measurement applications.
