Series Anritsu MS2840A - Announced in 2016, a range of affordable spectrum analyzers with a wide frequency range (up to 44.5 GHz) and the best phase noise in its class. Most modern spectrum analyzers (eg. MS2830A) support the wideband measurement and demodulation functions required for wireless networks (LTE, WiMAX, W-CDMA, etc.), however, only a small part of these solutions also support the high-quality narrowband measurements required in the production of microwave components, in wireless backbone networks and mobile radio communication systems of the VHF band.
New series MS2840A specially designed for such applications. It has many features, key among which are: an internal reference oscillator with significantly improved phase noise, support for high-performance waveguide mixers for millimeter-wave spectral measurements, and best-in-class phase noise at close carrier offsets.
This set of capabilities allows the MS2840A Series to be used to design and manufacture a wide variety of equipment, including millimeter and microwave wireless systems, 79 GHz automotive radar transmitters, and high frequency local oscillators. If necessary, the frequency range can be extended up to 325 GHz using external mixers.

Since the 2000s, most spectrum analyzers have been developed for mobile telecommunication applications, and their internal structure provides an optimal phase noise value at offsets of several MHz from the carrier. But for specialists who work with unmodulated signals or signals with a narrow modulation bandwidth, a spectrum analyzer is needed with good phase noise at small offsets from the carrier: 10 kHz or less.
The Anritsu MS2840A analyzer provides excellent performance for both wideband modulated signals and unmodulated and narrowband signals. As an example, this figure shows a 1 GHz test signal measured by the Anritsu MS2840A analyzer with a Span of only 25 kHz. Notice the minimal distortion when measuring the test signal and the impressive dynamic range (around 120dB).
Dedicated, optimized architecture of Anritsu MS2840A spectrum analyzers
The Anritsu MS2840A analyzers have a completely new architecture, specially optimized for both wideband and narrowband signals. These analyzers provide excellent measurement capabilities even at a carrier offset as low as 10 Hz!
At a 10 Hz offset from a 1 GHz carrier, phase noise is at a record level of -80 dBc/Hz.
These graphs show phase noise levels for different carriers: 1 GHz, 6 GHz, 15 GHz, 20 GHz, and 40 GHz. Note that these values are provided as standard with the MS2840A Series analyzers. By installing the optional MS2840A-066, the phase noise of the 3.6 GHz and 6 GHz models can be further improved.
Built-in signal analyzer
Any MS2840A Series Spectrum Analyzer comes standard with signal analyzer with an analysis bandwidth up to 31.25 MHz (with the help of options this bandwidth can be extended up to 125 MHz). The following additional measurements are available in signal analysis mode: power vs. time, frequency vs. time, phase vs. time, CCDF/APD measurement, spectrogram.
In addition, the analyzed signal can be recorded in the instrument's internal memory and re-displayed on the screen at any time. The recording duration depends on the selected signal analysis bandwidth and ranges from 0.5 seconds (for the 125 MHz bandwidth) to 2000 seconds (for the 25 kHz bandwidth).
Automated Phase Noise Measurement of Various Devices (Option MS2840A-010)
When activating the MS2840A-010 option in the Anritsu MS2840A spectrum analyzer, it becomes possible to automatically measure the phase noise values of the devices under test at various offsets from the carrier. The figure below shows phase noise measurements with a 1 GHz test signal and carrier offsets ranging from 1 kHz to 10 MHz.
Automation of Radar Measurements (Option MX284059A)
When the software option MX284059A is activated in the Anritsu MS2840A spectrum analyzer, it becomes possible to automatically measure the parameters of pulse modulation and linear frequency modulation (chirp) radar signals. Measured parameters include power, frequency, pulse width, rise and fall times, frequency deviation, 40 dB bandwidth, and more. .5 GHz.
This table summarizes the main features of the MX284059A option. For more information, see below on this page in the section Documentation.
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.
All necessary connection interfaces and control connectors as standard
The Anritsu MS2840A Spectrum Analyzer comes standard with all popular remote control interfaces: USB, Ethernet and IEEE-488 (GPIB), which allow you to control the operation of the analyzer using a computer, as well as include it in automatic measuring systems. A detailed guide to remote control commands contains 1400 pages and is freely available for download in PDF format.
In addition to interfaces for connecting to a computer, there are several service connectors on the rear panel of the MS2840A, the main of which are:
- intermediate frequency output (IF Output) 1.875 GHz;
- reference frequency input 5 MHz, 10 MHz and 13 MHz;
- reference frequency output 10 MHz;
- external trigger input (Trigger Input).
