Experience is in medium volume production
where "design for manufacturing", "design for
test" and overall solution cost have been very
important. Please see Lance's resume

systems, some instrumentation experience
Knowledge of field strength confirms primary coverage over the city of license, quantifies additional areas served by the station, and assures directional protection of distant co-channel stations from Z Technology
The first article of this two-part series explores the basic concepts and techniques of antenna pattern measurement and evaluates the benefits and drawbacks of various measurement methods. The concepts relating to near-field and far-field pattern testing are discussed as well. The second article presents the theory and equations governing antenna properties and includes a complete description of a site calibration for pattern-measurement testing. By Dr. Michael D. Foegelle.
There are many antenna types available for signal coverage measurement. This application note will discuss some of the factors you should consider in making a selection, from Z Technology.

Test methodologies must evolve as GSM and WCDMA combine with High-Speed Downlink Packet Access. Dr. Salim Manji, Spirent Communications -- Test & Measurement World, 2/1/2006
Noise Com provides off the shelf as well as custom designed noise testing solutions including analog / digital noise sources, BER testers, noise diodes, noise sources.
Engineers are working with mixed-signal designs, which contain a substantial mix of both analog and digital technology. Designers increasingly want equipment that allows them to time-correlate both the analog and digital domains in a single instrument. Traditionally mixed-signal analysis was accomplished by using a standalone oscilloscope and a logic analyzer; a two-box solution. The need to correlate analog and digital waveforms has led to the development of the mixed signal oscilloscope.
