Application Note

This versatile field device generates signals that mimic various sensors to test and calibrate equipment. It helps technicians troubleshoot connections and verify system performance. Portable and battery-powered, it's designed for on-site diagnostic work in industrial environments.

For optimal performance in over-the-air RF systems, antennas must meet specific requirements. Performance parameters like size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Methods of measuring the transmission (or reception) pattern that determines antenna gain with a VNA will be examined in this article.
