Europe : A new handheld 3G and 4G handheld base station analyzer has been released by Anritsu.
The new kit is the BTS Master MT8221B and users are likely to be cellular site personnel and RF engineers who would primarily use the analyzer for testing and commissioning of base stations and cellular installations.
Another prime use of the BTS Master MT8221B is for maintenance and fault-finding of 3G and 4G wireless networks for target levels such as calls dropped, refused calls, calls blocked, interference levels and fault diagnosis.
The analyzer’s platform offers a 20 megahertz demodulation feature for LTE and WiMax measurements and a 30 megahertz feature for external modulation of other wideband signal verification.
Established 3G and 4G networks being rolled out can be tested with the BTS Master MT8221B. The analyzer can measure the RF quality and modulation quality of a wireless signal to verify the performance of virtually every subsystem in a base station's transmitter. Downlink Over-the-Air (OTA) Quality tests verify the performance of the downlink with the OTA scanners.
Software for Easy Data Transfer, Reporting the BTS Master comes with Master Software Tools (MST) that allows data acquired by the analyzer to be easily transferred to a computer. MST saves significant time generating reports by utilizing the Trace Rename Utility and Group Edit. Efficient review of up to a week's worth of data collected by the BTS Master can be consolidated into one file through MST's Folder Spectrogram's 3-D view, which allows users to zoom into acquired data and provides independent 3-axis rotation control.
MST also provides a Remote Access Tool (RAT) to monitor and control the BTS Master remotely over the Internet. With the tool, supervisors can remotely verify measurements that have been taken in the field. RAT also saves cost by creating un-staffed remote listening posts for interference analysis, thus freeing up technicians for other trouble spots.
The BTS Master MT8221B is small (315 x 211 x 94 mm), lightweight (4.9 kg), and battery operated, making it easy for technicians to use it anywhere at a cell site. In less than 5 minutes, measurements can be made. The analyzer uses the field-proven design of all Anritsu handheld instruments, which means the BTS Master MT8221B will deliver reliable performance in rugged outdoor environments.
All key field measurements can be made with the BTS Master MT8221B. Technicians and engineers can conduct line sweeps, analyze components and antennas, troubleshoot down to a field replaceable unit (FRU) in the base station, verify the performance of the cell site's backhaul lines, and locate hard-to-find interference problems with the BTS Master MT8221B. The BTS Master MT8221B has a delivery of 6 to 8 weeks ARO.
