Fast Phase Noise Measurement of High Performance OCXOs


  • The unique architecture of the Holzworth HA7062C enables use of external high performance LOs for fast phase noise measurement at noise floors better than -190 dBc/Hz
  • The HA7062C's cross correlation engine provides automated phase noise test to reduce test time and save production cost.
  • 'AM Immune' Holzworth hardware design ensures 'AM Noise' does not influence phase noise measurement (Cross Spectral Collapse).
