Transmitter Measurements for BTS and Mobile Stations
Show Description
This application note describes the key RF parametric measurements necessary to characterize PDC (Personal Digital Cellular) and NADC (North American Digital Cellular) transmitters in both Base Transceiver Stations (BTS) and Mobile Stations (MS). New test instruments are making these measurements easier to perform, faster and more precise.
This paper is meant to enhance the reader’s understanding of the requirements of PDC and NADC transmitter RF parametric tests. It is also intended to be a useful reference for engineers in research and development, manufacturing, quality assurance, and field service. However, some modification and optimization of the information provided may be needed to meet the specific requirements of each of these areas.
For each measurement, examples of setup, method, and specification limits are given. These have been derived from the ARIB and EIA/TIA standards.
