The Anritsu Installation, Maintenance and Optimization Solutions portfolio is a coordinated family of field test instruments designed for wireless network technicians and engineers working on antenna systems, backhaul and fronthaul links, base stations, and the air interface. Rather than a single product, this is an ecosystem spanning cable and antenna analyzers, spectrum analyzers, PIM analyzers, OTDRs, transport analyzers, fiber inspection microscopes, and interference hunting systems — each tool addressing a specific layer of the wireless network test workflow.

Anritsu positions this product family around network reliability as the primary commercial driver, noting that poor network reliability is a leading reason wireless subscribers leave a network, and that key performance indicators such as blocked or dropped calls, dropped data sessions, and low throughput are the metrics operators monitor most closely. The portfolio targets the multiple challenges operators face co-siting 5G technology alongside legacy LTE and 2G infrastructure, deploying remote radio heads (RRH) using the optical CPRI interface for fronthaul, supporting advanced MIMO transmission, providing in-building coverage via distributed antenna systems (DAS), and addressing rising passive intermodulation (PIM) and interference levels — all while keeping installation, maintenance, and optimization costs controlled.

Brand Heritage

Anritsu is a Japanese precision measurement company with roots reaching back to 1895. Its position in wireless infrastructure RF test was substantially shaped by the 1993 acquisition of Wiltron Company, which brought core RF and microwave measurement technology and a North American commercial presence into the Anritsu portfolio. Instruments originally sold under the Wiltron brand are functionally part of the Anritsu lineage today.

Compare Other Models in This Series

The Anritsu Installation, Maintenance and Optimization Solutions family is organized by network layer rather than by a single performance tier. Each instrument addresses a specific test domain: cable and antenna systems (Site Master), spectrum and signal analysis (Spectrum Master, BTS Master, Cell Master, Field Master Pro), PIM testing (PIM Master), optical fiber and transport (Network Master, ACCESS Master, Network Master Pro), and connector endface inspection (Video Inspection Probes). Selecting within the family is primarily an application question, not a price-tier question.

Across the air interface and antenna system layer, the family scales from handheld Site Master cable and antenna analyzers covering frequencies through 40 GHz on the S820E, through Spectrum Master models from MS2711E up to the benchtop-class MS2720T handheld, to the Field Master Pro MS2090A which extends RF spectrum analysis to 54 GHz with 100 MHz analysis bandwidth and 5G NR downlink analysis capability. The BTS Master MT8220T and Cell Master MT8213E combine multiple instruments into single base station signal analyzers.

Each pre-owned Anritsu instrument linked below is its own product page with condition-matched pricing and configuration details. The base station test portfolio includes a mix of models — some are current production, some are mature platforms still actively used in cellular tower commissioning and maintenance — and the right choice depends on the specific frequency coverage, network layer, and field application your team supports.

The family differences fall along clear lines. For cable and antenna analysis, the Site Master models step up by frequency coverage (S331L/S33xE/S36xE through the S820E to 40 GHz) and by integrated capability (some models add spectrum analyzer functions and CPRI RF support on specific S331E, S332E, S361E, and S362E variants). For spectrum analysis, the MS2711E/12E/13E handhelds and MS2720T handheld benchtop scale by frequency range and analysis depth, with the Field Master Pro MS2090A positioned at the top of the family for 5G NR work with 100 MHz analysis bandwidth to 54 GHz.

On the transport and optical side, the Network Master MT9090A serves as a pocket OTDR and gigabit Ethernet analyzer in compact form, the ACCESS Master MT9085 Series provides a larger 8-inch touchscreen full-featured OTDR with PDF reporting, and the Network Master Pro MT1000A delivers comprehensive transport analysis from 1.5 Mbps to 10 Gbps covering eCPRI, CPRI, OBSAI, Ethernet, SONET/SDH, OTN, and Fibre Channel. The PIM Master MW82119B is differentiated by being the only instrument in the family that performs PIM vs. Time, Swept PIM, and Distance-to-PIM measurements — a capability set that is non-substitutable when 5G or LTE site commissioning requires PIM certification.
