The Anritsu Spectrum Master MS2711B/D is a handheld spectrum analyzer built for field environments and applications requiring mobility. Its rugged, ultra-lightweight, battery-operated design lets users perform spectrum analysis measurements anywhere, free from AC/DC power requirements, while locating, identifying, recording, and solving communication system problems quickly. Covering 100 kHz to 3.0 GHz, it is intended for engineers and technicians installing, maintaining, or troubleshooting modern wireless communication systems, including finding the source of interfering signals.
Typical applications span transmitter spectrum analysis — occupied bandwidth, power, and modulation measurements, plus the location and identification of in-band, out-of-channel, and out-of-band spurious signals — and receive signal analysis, where it measures receiver sensitivity and locates sources of interfering signals. It also supports modulation identification, modulation depth, deviation, and spectral mask work, and signal strength mapping to determine the most suitable location for antennas, base stations, and repeaters or to pinpoint electromagnetic leakage in broadcast systems.
ValueTronics stocks and holds its own test-and-measurement inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois, so the instruments we list are equipment we keep on hand. Every pre-owned unit is inspected and functionally verified in-house before it ships, while new units ship factory-sealed exactly as received from the manufacturer. That combination lets buyers source this analyzer with confidence in both availability and condition.
The Spectrum Master family pairs two handheld spectrum analyzers — the MS2711B and the MS2711D — that share a common 100 kHz to 3.0 GHz frequency range, rugged battery-operated packaging, and a standard built-in preamplifier. Both deliver synthesizer-based performance, one-button channel power, occupied bandwidth, and ACPR measurements, and the same Type N 50 Ω RF input.
Within that shared platform, the two models diverge in resolution bandwidth, sensitivity, display options, and the option set each can carry. The MS2711B centers on tracking-generator-based work, while the MS2711D adds finer resolution bandwidth, deeper sensitivity, and transmission and power-measurement options.
Each pre-owned model below is listed on its own dedicated product page with condition-matched pricing, so you can select the MS2711B or MS2711D configuration that fits your application and budget. The specifications shown here apply across the family; confirm the exact model on its individual page before ordering.
The clearest differences appear in resolution bandwidth and sensitivity. The MS2711B offers resolution bandwidths of 10 kHz to 1 MHz and preamp-on sensitivity to –115 dBm, while the MS2711D narrows resolution bandwidth to 100 Hz and reaches –135 dBm for work on lower-level signals. The MS2711D also provides finer attenuator resolution in 1 dB steps versus 10 dB steps on the MS2711B, along with a faster full-span sweep.
The models also differ in display and options. The MS2711B uses a VGA monochrome LCD and accepts the Option 20 tracking generator, whereas the MS2711D offers a VGA color or monochrome display and supports transmission measurement (Option 21), a power meter (Option 29), and the FCN4760 frequency converter. The comparison table below details the per-model frequency span, sweep time, sensitivity, and maximum input specifications.

Important: Maximum input level without damage: +23 dBm (MS2711B) or +43 dBm peak (MS2711D), ±50 Vdc.
Important: Option availability differs by model: Option 20 (built-in tracking generator) is for the MS2711B only; Option 3 (color display), Option 6 (frequency converter controller module for FCN4760), Option 21 (built-in transmission measurement), and Option 29 (power meter) are for the MS2711D only.
Important: For any prolonged storage period, Anritsu recommends the NiMH battery be stored separately between 0°C to 40°C.
Important: FCN4760 Frequency Converter specifications apply only when the converter is connected to the MS2711D spectrum analyzer, which requires Option 6 (frequency converter controller module).
Recommended pairing: the FCN4760 Frequency Converter extends the MS2711D to a 4.7 GHz to 6 GHz range and requires the Option 6 frequency converter controller module.
