Field Master Pro

Handheld Spectrum Analyzer delivers the highest continuous frequency coverage and real-time spectrum analysis bandwidth up to 110 MHz to address current and emerging applications

Frequency Range: 9 kHz to 9/14/20/26.5/32/43.5/54 GHz

Anritsu’s Field Master Pro MS2090A real time spectrum analyzer delivers performance never previously available in a compact, handheld instrument. With continuous frequency coverage from 9 kHz to 54 GHz, the Field Master Pro MS2090A is specifically designed to meet the test challenges of a full range of other wireless technologies in use today, including: 5G, LTE, wireless backhaul, aerospace/defense, satellite systems, and radar.

The Field Master Pro MS2090A delivers the highest levels of RF performance available in a handheld, touchscreen spectrum analyzer, with a displayed average noise level (DANL) of -164 dBm and Third Order Intercept (TOI) of +20 dBm (typical). This makes measurements such as spectrum clearing, radio alignment, harmonic, and distortion even more accurate than previously possible. For modulation measurements on digital systems, 110 MHz modulation bandwidth coupled with best-in-class phase noise performance maximizes measurement precision, while ±0.5 dB typical amplitude accuracy provides confidence when testing transmitter power and spurious.

Ruggedized for field use, all versions provide a comprehensive range of features to speed and simplify measurement, as well as enhance usability. RTSA spans of 22 MHz (standard) to 110 MHz (optional) provide capability for cellular interference monitoring to full ISM band signal analysis. In addition to being a full span swept tuned spectrum analyzer, all versions include a spectrogram display that helps monitor the RF spectrum for intermittent or interfering signals. Integrated channel power and occupied bandwidth measurements simplify the measuring and characterizing of common radio transmission. IQ data capture of 5G frames enables the capture and saving of IQ data for off-line processing on a PC using standard data analysis tools.

Atomic Clock External Frequency Reference for Handheld Instruments

With an extremely low power consumption of <200 mW, the MA25401A brings the accuracy and stability of an atomic clock frequency reference to Anritsu’s handheld products. The MA25401A Atomic Clock Frequency Reference has short-term stability (Allan Deviation) of 3.0e–10 @ t = 1 sec, typical long-term aging of <9e–10 per month, and maximum frequency change of ±5e–10 over an operating temperature range of –10 °C to 55 °C. The MA25401A 10 MHz output may be used to synchronize the internal frequency reference to an external reference clock to within 5 ppb accuracy. A USB C interface is used for power.


MA25424A IQ Data Converter is required in order to stream data from the Field Master Pro MS2090A spectrum analyzer to the Bird IQC5000B RF record and playback system.

PC based VSA software for use with IQ data captured from a Field Master Pro MS2090A Handheld Spectrum Analyzer.

MX280005A Vector Signal Analysis PC software for Field Master Pro MS2090A is for testing physical layer modulation quality of various transmission standards. It serves a wide variety of markets, from aerospace to public safety (TETRA) to satellite communications and commercial electronics (ZigBee, Wi-Fi).

The MX280005A Vector Signal Analysis PC software is designed to perform physical layer modulation analysis of common communication transmitter signals. During the design and manufacturing stages of a wireless communication system, it is common to measure the modulation quality with benchtop instruments. Using the IQ capture option of the Field Master Pro MS2090A (Option 128 required) together with the MX280005A software these measurements can be validated in a field environment. Framed and unframed signals are supported. In framed mode, the software decodes common wireless signals including public safety (TETRA, P25, and DMR) to aerospace and satellite communications. In unframed mode, the software analyzes continuous modulation such as DQPSK, QAM, ASK, and FSK. The Field Master Pro MS2090A supports IQ captures up to 110 MHz bandwidth meaning narrow band communications signals or wideband satellite downlink signals can be captured and analyzed with the same application.

MX280005A software can initiate the capture of IQ data from a Field Master Pro MS2090A over an Ethernet connection or a data capture can be triggered manually through the Field Master Pro MS2090A touchscreen. Multiple analysis formats are provided including signal spectrum, EVM, constellation diagrams, eye diagrams, and numeric result tables. A comprehensive insight into all aspects of the transmitter performance is provided as multiple results windows can be displayed simultaneously.

The 5G Evolution of Indoor Wireless Networks for Smart Buildings and Manufacturing Facilities

5G technology has introduced some exciting possibilities for in-building functions. The “smart” buildings and manufacturing facilities of tomorrow will include new functions such as IoT, factory automation, machine learning devices, and cloud compute applications. To handle these new features, network architectures will change, frequency bands will be added, and new network features will be introduced. In this webinar, we will examine how the indoor wireless networks will evolve as we move to 5G, and the challenges in managing these complex networks to ensure performance and reliability for both commercial as well as the public safety networks.

Understanding Real-Time Spectrum Analysis

Real-time spectrum analysis (RTSA) provides signal insight previously only available in high-end lab and benchtop solutions. RTSA allows gapless capture and display of rapidly changing and highly intermittent signals. The digital nature of RTSA also makes a variety of analysis and display technologies possible that traditionally required multiple hardware platforms.


Delivering the highest levels of performance available in a handheld RF spectrum analyzer, the Field Master Pro MS2090A instrument gives field engineers and technicians unparalleled measurement accuracy previously reserved for only benchtop instruments.

  • Interference hunting and spectrum clearing networks – fast sweep speeds, low distortion front-end, and spectrogram display help deploy new network efficiently, ensuring spectrums are clear and validating that all legacy users have stopped all transmission.

  • Broadcast transmitter analysis – a comprehensive range of transmitter measurements – including: harmonic, spurious, occupied bandwidth, channel power, and adjacent channel power – ensures conformity to regulatory requirements

  • Microwave radio links – with a frequency option up to 54 GHz and exceptional sensitivity for dish alignment, power and modulation bandwidth can be verified during installation or maintenance testing with a waveguide horn antenna.

  • Satellite system monitoring – ideal for monitoring downlink signals to search for interference and noise

  • Pulse Radar Measurements - The wide bandwidth of the MS2090A enables detailed analysis of pulsed radar signals. In zero span, resolution bandwidth can be set as high as 40 MHz (option dependent), enabling a sweep time as low as 60 ns and amplitude measurements of pulses as narrow as 20 ns.

  • 5GNR base station measurement – validate the performance of the gNB base station with essential measurements that are in full compliance with 3GPP TS 38.104 V15, including:
    • frequency error
    • time offset
    • cell/sector ID
    • modulation quality
    • unwanted emissions
    • occupied bandwidth
    • adjacent channel leakage ratio
    • transmitter spurious to 12.75 GHz
    • EIRP
    • synchronization signal block (SSB)

  • 5G coverage mapping – receive a clear representation of the signal strength of 5G transmitters over intended geographic area by continuously measuring RF data – including 5G channel power, EIRP, or RSRP – with results graphically displayed on a digital map or building floor plan.
