Notes

  • Poseidon Scientific Instruments has a continuous development policy and features are subject to change without notice.
  • Phase and amplitude noise measurements are based on techniques specified in National Institute of Standards and Technology (NIST) Technical Note 1337.
  • Supplemental characteristics are supplied to provide further useful information and should be treated as “typical” performance. Actual performance may vary depending on operating environment and other factors.
