The Anritsu MT8221B BTS Master is a handheld base station analyzer engineered for installation and maintenance of cellular network infrastructure. It delivers integrated cable and antenna analysis, spectrum measurement, and power metering across 150 kHz to 7.1 GHz, with support for 2G, 3G, 4G LTE, and WiMAX standards. The instrument combines a 20 MHz LTE demodulation engine, 30 MHz Zero-Span IF output for external wideband signal processing, and an optional Vector Signal Generator for receiver validation.
