[Legacy Report] Internal Development of Test and Measurement Hardware for Wireless Infrastructure Applications
#IMS
The cost pressures on commercial infrastructure component manufacturers have forced organizations to explore innovative solutions to reduce test costs. For some manufacturers, viable options to address specific test and measurement needs must be developed internally. Andrew Corporation decided to design our own hardware to determine whether cost savings are possible while maintaining the necessary performance criteria needed to test our commercial wireless infrastructure hardware. Utilizing a highly-focused, small development team and a straightforward goal to reduce cost, we decided to develop a line of modular hardware that may be used by R&D, reliability and production test and measurement needs. We have successfully developed an Arbitrary Waveform Generator (ARB), Digital Upconverter, CW Signal Source and Reflectometer that are used in Vector Signal Generators (VSGs) and Vector Network Analyzers (VNA’s) which are currently in use throughout the organization. Our work has resulted in a significant reduction in our capital equipment expenditures as well as a new product line which may be marketed as a lower cost alternate to the RF & Microwave Test and Measurement industry.
