The Anritsu ME453M Microwave System Analyzer is a precision instrument for frequency and power measurements across microwave transmission systems. It delivers detailed analysis of transmission line characteristics in Baseband (BB) and Intermediate Frequency (IF) bands, supporting both linear and non-linear distortion measurement. Engineered for defense, broadband communications, and satellite systems, the ME453M validates high-frequency signals in FDM-FM relay systems, digital microwave radio links, and satellite communication networks. The instrument combines measurement precision with operational simplicity, making it essential for link device adjustment, construction, maintenance, and R&D applications.
Technical Specifications
Frequency coverage spans 70 MHz band (45 to 95 MHz) and 140 MHz band (90 to 190 MHz), with swept IF signal ranges of 45 to 90 MHz (70 MHz band) and 90 to 190 MHz (140 MHz band). Variable side markers accommodate ±25 MHz (70 MHz band) and ±50 MHz (140 MHz band). Baseband frequency range extends from 66.7 kHz to 12.39 MHz with automatic selection. Eight BB frequencies are selectable via pushbutton control; Option 05 adds one specified frequency at 55.6 kHz or 27.8 kHz. Modulation frequency ranges from 18 to 100 Hz.
