Datasheet

Anritsu’s MT8220T BTS Master is a multi-function handheld durable tester with all the capabilities network operators, sub-contractors, installers, and regulatory authorities need when measuring base stations. The third generation of Anritsu’s field-proven BTS Master family, the new tester has improved performance, including a standard GPS receiver, and enhanced two-port dynamic range.

Thinner and lighter than previous models, it also features faster LTE scanner, and expanded spectrum analysis capability. Combining a cable and antenna analyser, spectrum analyser, and internal power meter, the instrument offers line sweeping, comprehensive wireless measurements, ultra-sensitive spectrum analysis and sophisticated interference tracking in a compact handheld solution.

It also features a standard GPS receiver with antenna. By providing multiple testing capabilities, including comprehensive Over-the-Air (OTA) measurements to support Remote Radio Heads (RRH) and MIMO, the MT8220T is well suited for co-siting of new systems, such as LTE, with existing networks. Improving the cable and antenna analyser two-port dynamic range to >100dB (typical 110dB) over the key cellular frequency range of 400MHz to 2800MHz allows users to conduct cellular repeater testing where isolation measurements up to 100dB are required.

Dynamic range is also enhanced to >90dB between 2800MHz and 4000MHz, and >85dB up to 6000MHz. The built-in spectrum analyser, which provides frequency coverage of 15 kHz to 7.1GHz, has enhanced sweep modes, including Fast, Performance, and No FFT. The new tester also features Burst Detect, so users can capture and analyse fast, transient signals down to 200 µs duration and 1% duty cycle in a span up to 15MHz. This simplifies direction finding and signal locating of problematic interference signals.

A high-contrast, touchscreen display and backlit key panel enable convenient operation in both bright sunlight and dim conditions. The user has access to an options menu, which has the capability to place time-saving short cuts for frequently used functions on the main menu screen, and a virtual keyboard for fast and easy naming of saved files.

A number of options are available to add versatility and allow it to be used on almost any installed network. Bundled wireless measurement options allow users to conduct RF, demodulation, and OTA measurements on technologies such as CDMA and EV-DO, LTE FDD and LTE TDD, and Fixed and Mobile WiMAX. The bundled options also provide cost efficiencies to customers.
