Low-Cost High-Performance Signal Analyzer MS2850A for 5G and Wideband Signal Measurement

Release of High Cost-Performance Signal Analyzer MS2850A with 1 GHz Analysis Bandwidth

Anritsu Corporation (President Hirokazu Hashimoto) releases its low-cost high-performance Signal Analyzer MS2850A on May 29, targeting development and commercial production of 5G mobile communications systems.

The MS2850A with world-beating 1GHz analysis bandwidth supports evaluation of 5G multi-carrier signals,while installed 5G measurement software packages leverage the MS2850A’s excellent dynamic range and high flatness performance to cut measurement times using all-at-once,high-accuracy measurements of the 5G 800MHz modulation bandwidth (eight 100MHz band carriers).

[Development Background]

North America, S. Korea, Japan, and China are leading the world’s nations in examining introduction of next-generation 5G cellular mobile communications systems with plans to start actual testing from late 2017 into 2018. Wireless equipment makers leading 5G development have started transitioning from the development and verification testing phases to development of commercial models and preparations for manufacturing. Holding down future large infrastructure costs is a major issue for makers who urgently need a high-performance but cost-effective 5G signal analyzer meeting both development and manufacturing requirements. Furthermore, other non-5G communications fieldshave the same requirements as 5G whenbroadband communications come into use offering larger data capacity at faster speeds.

[Product Outline]

<New Products>
■ Signal Analyzer MS2850A
Frequency:                  9kHz to 32GHz/44.5GHz (two models)
Analysis Bandwidth:     255MHz (standard), 510MHz (option), 1GHz (option)

■ 5G Standard Measurement Software (Base License)          MX285051A
Pre-Standard CP-OFDM Downlink (Rel.1)                         MX285051A-001
Pre-Standard CP-OFDM Uplink (Rel.1)                             MX285051A-051

The Signal Analyzer MS2850A supports Tx performance evaluations at wireless equipment development and manufacturing; the 32GHz and 44.5GHz measurement frequency models have an analysis bandwidth of 255 MHz as standard, which can be extended as an option up to 1 GHz. Noise Figure (NF) and Phase Noise measurement functions required for basic evaluations of wireless communications equipment can be installed in both models.

Installing the 5G measurement software packages in the MS2850A supports measurement of 5G uplink and downlink signal frequency error, power, EVM, etc., using CP-OFDM modulation. Additionally, downlink measurements evaluate multi-carriers all at once.

Not only does the MS2850A support all previous cellular technologies such as, LTE, W-CDMA, TD-SCDMA, and GSM, it also offers futureproof support for the new 5G standards now under discussion by 3GPP.

[Key Features]
■ Signal Analyzer MS2850A
Excellent Dynamic Range and Flatness Performance for Wideband Signal Analysis

The MS2850A hardware has both excellent dynamic range and flatness performance, which are critical for evaluating wideband wireless signals accurately and improving the quality of wireless communications equipment.

Specifications at 28 GHz
Amplitude Flatness: ±1.2dB (at Center Frequency ±500 MHz)*1
Phase Flatness: 5° p-p (at Center Frequency ±500MHz)*1
ADC Clipping Level: 0dBm*2
DANL: –141dBm/Hz*2
SFDR: –70 dBc*1

■5GStandard Measurement Software (Base License)            MX285051A

Pre-Standard CP-OFDM Downlink (Rel.1)                         MX285051A-001
Pre-Standard CP-OFDM Uplink (Rel.1)                             MX285051A-051

Three software packages leverage the excellent dynamic range of the MS2850A to achieve anEVM performance of <1%*2,3.

At downlink measurement, the all-at-once multi-carrier analysis function improves measurement and testing efficiency by shortening times for relative comparisons of characteristics of each carrier, timing errors, and general characteristics for all carriers.

■ Cutting Infrastructure Investment Costs

Unlike extremely expensive wideband signal analyzers for leading-edge R&D, the MS2850A is the world’s leading middle-price-range, wideband signal analyzer. Anritsu is releasing it now to respond to customers’ growing need to proactively cut costs while investing in new infrastructure for the rapidly developing 5G market.

[Target Markets and Applications]
