The Agilent/Keysight 8565A Spectrum Analyzer delivers high-performance RF signal analysis from 10 MHz to 22 GHz, with external mixer capability extending coverage to 40 GHz. This instrument combines a wide dynamic range of +30 dBm to -106 dBm with exceptional noise performance (DANL of -149 dBm/Hz) and phase noise below -113 dBm/Hz at 10 kHz offset, making it ideal for detailed characterization of complex signals across telecommunications, aerospace, and manufacturing test environments.
The analyzer features continuously variable frequency span independent of bandwidth, fast digital resolution bandwidths down to 1 Hz, and Gaussian-shaped resolution filters for repeatable measurements. Absolute amplitude calibration spans 0.01 GHz to 22 GHz with ±1.0 dB accuracy, while logarithmic display accuracy maintains <±0.1 dB/dB across the full 70 dB range. Built-in preselection minimizes spurious responses, and residual response performance remains below -90 dBm under fundamental mixing conditions (0.01 to 4.1 GHz).
