The CPRI's BTS Master-based RF measurement option offers best-in-class sweep speed and unique testing capabilities, and also enables field engineers and technicians to perform accurate RF measurements on Remote Radio Heads (RRH) at ground level, eliminating the time and considerable expense associated with sending a tower team to perform such interference measurements.
With the new option installed, the BTS Master can perform RF measurements over the fiber optic CPRI link connecting the baseband unit (BBU) and the RRH. Anritsu has developed pre-configured radio settings and an auto-detection function as an option to simplify CPRI link setup for RF measurements.
Its sweep speed, 10 times faster than other solutions in its class, allows the CPRI's BTS Master-based RF measurement test suite to capture burst signals undetected by other methods. This sweep speed is complemented by two unique features: the ability to tune and display the path of a visualized signal, as well as to zoom in on a specific area of interest. Faster sweep speeds and more detailed signal analysis enable engineers and field technicians to more efficiently locate sources of interference and PIM.
Users can perform CPRI spectrum and spectrogram measurements with this option. Its performance and capacity provide operations and maintenance teams, RF performance engineers, NEM performance teams, and other professionals responsible for wireless network optimization with the ability to perform all necessary tests without the cost and time required to deploy a tower team.
The CPRI RF option expands the already extensive measurement capabilities of the BTS Master family, which includes the MT8820T, MT8221B, and MT8222B. All of these portable base station analyzers have been specifically developed to support 2G/3G/4G wireless networks and incorporate more than 30 analyzers into a single instrument to cover virtually all measurement needs.
Anritsu also offers a catalog of optical transport meters for testing and verifying CPRI links. These solutions leverage Anritsu's extensive experience in optical testing and can be used to confirm that the RRH is properly powered, that the fibers are correctly connected, the condition and cleanliness of the optical connector, and that the link does not have excessive loss between the RRH and the BBU. The transport meters can also verify that the SFP/SFP+ modules have been installed with the correct wavelength and that the modules can operate at the configured speed.
