The Agilent/Keysight 08922-61045 is the A18 Spectrum Analyzer assembly for the HP 8922 Series GSM Test Set. It receives a 114.3 MHz input signal from the A16 Receiver assembly and performs downconversion, amplification, filtering, and detection via phase-lock loop (PLL) architecture. The assembly analyzes frequency spans up to 4 MHz and provides real-time RF signal visualization for component verification and diagnostic testing across the GSM measurement platform.
Technical Specifications
