Anritsu announces the expansion of the functionality of the Field Master™ spectrum analyzer for measurements in LTE and 5G
networks. As the deployment and consolidation of 5G networks accelerate, the deterioration in network performance as a result of interference in the TDD uplink is becoming more noticeable. The latest version of the Field Master software provides dual display of the LTE or 5G frame structure with automatic placement of gateways in uplink slots along with the radio frequency spectrum of closed time intervals.
For 5G networks in coastal or mountainous areas, radio frequency downlink transmissions easily become the object of atmospheric-tropospheric channels. The signals can travel hundreds of kilometers, which leads to a temporary displacement relative to a remote base station. As a result, the power of the descending channel masks the signals of the ascending channel from the user equipment. It is also important that there is a common staffing interval format deployed across all operator networks in the country, and ideally at international borders. The new uplink interference measurement includes configurations for common frame interval formats recommended by international standards organizations, including GSMA, ITU-R and ECC/CEPT.
Anritsu's Field Master Spectrum Analyzer with LTE and 5G measurement capability is the preferred test instrument for regulators and operators around the world. Adding this uplink interference measurement adds value by providing detailed information about common causes of interference in new TDD networks.
5G and LTE measurements are available for the Field Master Pro MS2090A, covering the FR1 and FR2 frequency ranges, and the new Field Master MS2080A, designed only for FR1 networks. In addition to 5G and LTE measurements, the spectrum analyzer captures the detailed spectrum of the transmitter in real time, and the auxiliary cable and antenna analyzer facilitates the inspection of feeder cables.
