Multifunction Spectrum Analyzer Pushes 6 GHz to Support 5G FR1

April 13, 2023
Anritsu extended the frequency range of its Field Master MS2080A multifunction spectrum analyzer to better address interference hunting and network verification applications.

Anritsu enhanced its Field Master MS2080A multifunction spectrum analyzer to operate up to 6 GHz. Combining nine instruments into a single solution, the extended frequency coverage enables the MS2080A to address the growing congestion in the 6-GHz spectrum. 

The compact and portable device helps troubleshoot interference and intermodulation issues that can degrade network performance, addressing base-station installation and maintenance (I&M), as well as other applications. At 6 GHz, the MS2080A offers a sweep speed of 45 GHz/s to enable analysis over wider spans.

Advanced features include AM/FM audio demodulation, as well as best-in-class RF performance such as ±1-dB amplitude accuracy. It also supports cable and antenna analyzer, power meter, and 5G/LTE analysis to serve measurement tasks in both legacy and emerging wireless networks.

Furthermore, Anritsu offers an AM/FM-modulation-quality measurement option for all instruments in the Field Master family, enabling full characterization of broadcast transmitters. A single 10-in., 1280x800-resolution screen displays RF spectrum, audio spectrum, and audio oscilloscope information, as well as modulation quality and distortion values. An optional real-time spectrum analyzer offers a 2-µs probability-of-intercept, with an analysis bandwidth up to 40 MHz and DANL of less than 150 dBm.

Capable of capturing intermittent and digitally modulated signals that are difficult to identify, its spectrograms allow for irregular and drifting signals to be captured, recorded, and displayed.

The MS2080A performs a variety of measurements for 5G FR1 radios supporting I&M of 5G NR and LTE base stations. Among them is gated sweep analysis for transmitter-quality measurements provided to verify FR1 carriers with 100-MHz bandwidth, and full-channel, power-based, and 5G/LTE-modulation-quality measurement-based coverage mapping for accurate over-the-air (OTA) testing.

A rugged device for the most challenging environments, its display meets the IK08 specification for direct knocks and drops, and it's presented as the only instrument in its class with 5 W of continuous RF input overload protection. This can prevent damage to the instrument’s front-end when used close to high-power transmitters or in a high-signal-level environment. A soft case provides IP52 environmental protection to safeguard the lightweight (less than 4 kg) instrument during transport or rain.
