The Anritsu S412E LMR Master is a handheld multi-function analyzer built on the ninth-generation Anritsu platform for field installation and maintenance of Land Mobile Radio systems, public safety networks, and communication infrastructure. It combines cable and antenna analysis, spectrum analysis, signal generation, and interference detection in a single portable instrument. The 8.4-inch daylight-viewable touchscreen (800 × 600 resolution) displays measurements across a 500 kHz to 1.6 GHz operating range, with optional extension to 6 GHz. Weighing less than 7.6 lbs and operating for approximately 3 to 4.6 hours on battery, the S412E delivers field-grade performance with dynamic range exceeding 95 dB in 10 Hz RBW and patented RF interference rejection for accurate measurements in high-activity RF environments.
