The new 5G standards for sub-6 GHz signals will require analysis of Tx power, frequency error, EVM, etc. Major signal analyser manufacturers are upgrading their softwares to comply the same.
Anritsu Corporation has announced release of software options 5G Measurement Software (Basic License) MX269051A, NR TDD sub-6 GHz Downlink MX269051A-011 and NR TDD sub-6 GHz Uplink MX269051A-061 adding support for measuring the RF Tx characteristics of fifth-generation (5G) mobile communications base stations and terminals to their existing signal analyser MS2690A/MS2691A/MS2692A series.
Installing the above 5G Measurement Software and NR TDD sub-6 GHz options to the Signal Analyzer MS2690A/MS2691A/MS2692A series (MS269xA series hereafter) supports consistent 5G signal analyses, including Tx power, frequency error, EVM(error vector magnitude), etc., of 5G NR TDD sub-6 GHz signals expected to be adopted by the new 5G standard.
Users installing these software options in their MS269xA instruments can commence development of sub-6 GHz wireless equipment using the same familiar operations, helping bring commercial 5G products to market sooner.
Need of software upgrades in signal analyser
For sub-6 GHz testing there is a need to make use of the measuring instrument used in the mobile communication system of 4G/LTE or earlier. With this software release, the company claims to strengthen the functions of its M269xA series by adding support for 5G measurements to the other communications methods, including LTE/LTE-Advanced.
The 5G Measurement Software and 5G TDD sub-6 GHz options MX269051A are installed in the MS269xA main unit to support development and production of 5G wireless communication devices. These software options support signal analysis and measurement of RF characteristics by supporting 3GPP-compliant sub-6 GHz uplink and downlink signals and specifying 1CC (component carrier) up to a bandwidth of 100 MHz.EVM measurements of less than 0.5% using wide-dynamic-range performance at downlink 1CC 100-MHz bandwidth and 3.5 GHz center frequency. It also features built-in, one-button Auto-Range function for optimized EVM measurements.
With advent of 5G technology accurate signal analysis is a must. By addition of various options such as the built-in vector signal generator not only helps improve the quality of wireless equipment but will also cut the cost of sub-6 GHz measurements.
