The Anritsu Field Master Pro MS2090A is a high-performance handheld RF spectrum analyzer offering integrated, continuous frequency coverage from 9 kHz up to a model-dependent maximum of 54 GHz. Anritsu positions it as the culmination of over 60 years of microwave test and measurement development, bringing measurement accuracy previously reserved for benchtop instruments into a battery-powered, field-portable form factor designed for the unique needs of 5G networks while maintaining support for the full range of today's wireless technologies.

It is built for the field engineers and technicians who deploy, maintain, and troubleshoot wireless infrastructure. Listed applications span interference hunting and spectrum clearing, cross-border interference resolution, broadcast transmitter analysis, microwave radio-link alignment, satellite downlink monitoring, pulse radar measurement, and 5G coverage mapping. The instrument is aimed at wireless service providers, broadcasting, regulatory authorities, aerospace and defense, satellite systems, and radar.

ValueTronics holds its own inventory in a 20,000 square foot secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments we list are stock we physically control. Every pre-owned unit is inspected and functionally verified by our technicians before it ships, while new units ship factory-sealed exactly as received from Anritsu — we never open or test a new instrument.

Compare Other Models in This Series

The Field Master Pro MS2090A is offered as a series of frequency-tiered models that share a common platform, display, and feature set while differing in their maximum frequency coverage. Every model starts at 9 kHz and provides continuous, gap-free coverage up to a model-specific ceiling of 9, 14, 20, 26.5, 32, 43.5, or 54 GHz.

All models deliver the same core RF performance — including –164 dBm DANL with preamp, +20 dBm typical TOI, 100 MHz analysis bandwidth, and the 10.1 inch multi-touch interface — so the primary selection decision is how much frequency range an application requires. The same option catalog, from the real-time spectrum analyzer to the 5G NR and LTE base-station measurements, is available across the family.

Each pre-owned model below is listed on its own dedicated product page with condition-matched pricing. Select the frequency tier your application requires, then choose the pre-owned unit and configuration that fit your budget and timeline.

The models differ along two axes: maximum frequency and RF connector type. The 9, 14, and 20 GHz models use a Type N connector; the 26.5, 32, and 43.5 GHz models use a 2.92 mm ruggedized K connector; and the 54 GHz model uses a 1.85 mm ruggedized V connector. The comparison table below lists the frequency option number assigned to each model.

Weight also varies with configuration: the -0709, -0714, and -0720 versions weigh 5.06 kg (11.15 lb), while the -0726, -0732, -0743, and -0754 versions weigh 5.4 kg (11.9 lb).

Because harmonic, spurious, and transmitter measurements extend up to the model's frequency ceiling (option dependent), the chosen tier directly determines which signals a given unit can observe — only the higher-frequency models reach the 28 GHz and 39 GHz mmWave 5G bands referenced above. All other capabilities are shared across the series and configured through the common option set.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications
