Comparing CW and low duty cycle passive intermodulation (PIM) measurements

The measurement technique used by a PIM analyzer is CW or low duty cycle. The only traceable device available to independently validate a PIM analyzer’s measurement accuracy in the field is a PIM standard. For this technical discussion, the measurement techniques are explored and explained along with the fact that CW and LDC offer similar… Read more »

Testing passive networks in distributed antenna systems (DAS)

In the last decade, worldwide consumer demand for cellular services has driven network operators to strive for better network coverage and within that coverage footprint, better network capacity. Since more than 80 % of cellular traffic comes from inside a building, in-building coverage, and in-building capacity have become a focus of this effort. In addition,… Read more »

Remote Radio Heads in Today’s Evolving RAN Environment

Radio Access Networks (RAN) have evolved considerably from mobile access networks of the past and are helping to drive the “densification” of mobile networks allowing mobile operators to keep up with the heavy traffic demands brought on by 4G/LTE. In this webinar, we look at the forces behind the evolving wireless access network and the… Read more »

Measuring Multistandard Radio Base Stations

3GPP Release 9 Technical Specification (TS) 37.141 covers multistandard radio base station conformance testing. This application note introduces the concept of multistandard radio base stations as well as solutions for transmitter and receiver tests based on R&S® signal generators and R&S® signal and spectrum analyzers.
Application Notes:

LTE Over-The-Air Testing for Base Stations

This application note explains how to perform LTE base station measurements over the air (OTA) using the R&S®FSH4/8/13/20 handheld spectrum analyzer. It describes the required measurement setup and explains the results obtained with the different measurement modes.
