DETAILED DESCRIPTION

Spectrum and signal analyzers Anritsu MS2850A belong to the middle price range, but at the same time, have the ability to analyze signals with digital modulation, which surpasses even the most expensive models on the market. The MS2850A Series analyzers were originally designed as the primary tool for the development and deployment of 5G networks and other advanced broadband communications systems such as communications satellites and radio relay stations.

These instruments come standard with a 255 MHz digital demodulation bandwidth and software that provides measurements of all key spectrum parameters and a basic set of signal characteristics. With the help of hardware and software options, which can be viewed on this page in the section Options and accessories, can extend the digital demodulation bandwidth up to 1 GHz and measure all signal characteristics of 5G, LTE, W-CDMA/HSPA, GSM/EDGE, TD-SCDMA, and more.

Detailed Spectrum and Signal Analysis

The full operating frequency range is 9 kHz to 32 GHz for the MS2850A-047 and 9 kHz to 44.5 GHz for the MS2850A-046. In this range, the MS2850A analyzers work like classic sweeping (scanning) spectrum analyzers, which allows you to measure power versus frequency (spectrum), power versus time (in zero span mode), channel power, occupied bandwidth, power factor in adjacent channel (ACPR) and other parameters.

In addition, at any of the frequencies above 100 MHz, advanced analysis of signals in the 255 MHz and 510 MHz bands is possible, and at frequencies above 4.2 GHz, analysis in the 1 GHz band is possible. The signal in this band is digitized using a high-speed ADC and processed by a specialized processor using the Fast Fourier Transform (FFT) algorithm. This mode allows you to detect very short changes in the spectrum, record a spectrogram, perform vector signal analysis, measure all important wireless network signal quality parameters such as error vector amplitude (EVM), code domain power, and others, as well as display a constellation modulation diagram (diagram -constellation).

Simultaneous analysis of up to 8 channels (carriers) of a 5G signal

The Anritsu MS2850A Series analyzers allow you to simultaneously perform detailed analysis of multiple 5G carriers with a bandwidth of 100 MHz each. As standard, these analyzers support a signal analysis bandwidth of 255 MHz, allowing simultaneous operation with two 5G carriers. When the analysis option is set to 510 MHz, simultaneous operation with four carriers is possible, and when the analysis option is set to 1 GHz, simultaneous analysis of eight carriers is supported. For example, this screenshot shows the spectrum of 8 carriers of a 5G signal, the width of each channel is 100 MHz.

The Anritsu MS2850A analyzer measures the spectrum of eight 5G signal carriers. The modulation width of each carrier is 100 MHz.

Comprehensive information for each measured channel

For each measured channel, the Anritsu MS2850A spectrum and signal analyzers provide very detailed information on all signal modulation quality indicators and a lot of other important information. In total, more than 20 numerical parameters are measured and 6 types of graphs are displayed. The main parameters and five types of graphs are also measured in the multi-channel analysis mode. As an example, this table lists the measured parameters for 5G signals.

High accuracy measurement of wideband signals

The Anritsu MS2850A analyzers have very high accuracy in measuring the parameters of signals with wideband digital modulation. Due to their uniformity and wide dynamic range, when analyzing a 100 MHz 5G carrier with 64QAM xPDSCH modulation, they provide an error vector measurement error (EVM) of less than 1%.

And in a full 1 GHz analysis bandwidth, the Anritsu MS2850A analyzers have record-breaking amplitude and phase uniformity. So, with a center frequency of 28 GHz and an analysis bandwidth of 1 GHz, the amplitude unevenness does not exceed 1.2 dB, and the phase linearity is better than 5 degrees.

To achieve such high performance, the designers of the Anritsu MS2850A series used an ADC that does not saturate (does not overflow) even with an input level of 0 dBm. This design approach provides a significant advantage and increases the accuracy of the analysis of 5G, 4G and other broadband signals.

The main differences between different series of Anritsu laboratory spectrum and signal analyzers

Currently, the Japanese company Anritsu produces four series of laboratory spectrum and signal analyzers: Anritsu MS2830A, Anritsu MS2840A, Anritsu MS2850A and Anritsu MS269xA. All of them are made in a classic desktop case and have a unified user interface. However, these four series differ in terms of features (options), measurement accuracy and cost.

Series Anritsu MS2830A (up to 43 GHz) belongs to the middle class, both in terms of measurement accuracy and cost. It provides an excellent price/feature ratio and is well suited for a wide range of spectrum and signal analysis applications. It is worth emphasizing the excellent opportunities for working with commercial communication standards, for example: LTE, W-CDMA, GSM, WLAN, etc. (excluding 5G). The MS2830A Series instruments can analyze signals up to 125 MHz bandwidth, however, if the analysis bandwidth exceeds 31.25 MHz, then there must be no other signals outside the analyzed bandwidth, otherwise image frequencies will be generated.

Series Anritsu MS2840A (up to 44.5 GHz) has improved performance compared to the MS2830A, especially in terms of phase noise at small offsets from the carrier. Demodulation of commercial communication standards is not supported, but the MS2840A series is great for developing and configuring devices using proprietary digital modulations based on QAM, APSK, etc., as well as various analog modulations. Like the MS2830A Series, the MS2840A Series can analyze signals up to 125 MHz bandwidth, however, if the analysis bandwidth exceeds 31.25 MHz, then there must be no other signals outside the analysis bandwidth, otherwise image frequencies will be generated.

Series Anritsu MS2850A (up to 44.5 GHz) provides the same measurement accuracy as the MS2840A series, plus it can demodulate and analyze signals in a record-breaking 1 GHz bandwidth. This series is ideal for designing and customizing 5G equipment, as well as any devices that use wide modulation bandwidths, such as satellite communications systems or native broadband digital communications systems. Commercial standards (LTE, W-CDMA, GSM, etc.) are also supported. In addition, the MS2850A Series analyzers can record up to 3.9 GS/s of digitized signal to internal memory and transfer it to a computer for advanced analysis, while sampling rates can reach 1.3 GS/s, which allows you to analyze any signal in detail, including impulse.

Series Anritsu MS269xA (up to 26.5 GHz) belongs to the high class in terms of measurement accuracy, and costs a little more than the MS2840A series. The main feature of the MS269xA series is the ability to analyze signals with a bandwidth of up to 125 MHz without the appearance of mirror frequencies. Demodulation of commercial communication standards is supported: LTE, W-CDMA, GSM, WLAN, etc. 5G demodulation and analysis is also supported.

All series of Anritsu laboratory spectrum and signal analyzers can be equipped with a variety of additional options that solve various practical problems, for example: EMC preliminary tests, phase noise measurements, complex waveform generation with built-in vector generator, high-precision frequency measurements with built-in rubidium reference generator, etc. Please note that when using external mixers, the operating frequency range of some laboratory analyzers can be extended up to 325 GHz.

State of the art communication interfaces
