Signal Intensity Measurement

With the rapid development of China's TD-SCDMA system, how to qualitative and quantitative to judge intelligent antenna electromagnetic radiation pollution is a problem to be solved. Due to the special working principle of smart antenna, the second generation communication system spectrometer and field intensity meter measurement method is a complicated and difficult to operate. This paper introduces a design suitable for TD smart antenna measurement system: this system can realize in single user or multiple users at the same time and the TD base station set up calls link of multi-point synchronous signal intensity measurement. The measurement results of our system are very close to the measurement results of spectrometer field intensitys and can reasonable reflect TD stations around the extent of the electromagnetic radiation. This method of our system is easy, cheap and maneuverable

Power Measurements

The uncertainty of determining the sound power of HVAC equipment using the AHRI Standard 230 sound intensity measurement method is presented. Measurements of six different reference sound sources (RSS) at four different laboratories, by nineteen different individuals with four different instrumentation systems are presented. From 2004 through 2020, these measurements were performed as part of a training program at Johnson Controls HVAC test laboratories to qualify technicians and engineers on the use of sound intensity instrumentation. The results illustrate the reproducibility of sound intensity measurements using the scanning method of AHRI Standard 230.
