Test 3 — Stability
NOTE
High accuracy precision measurements of time stability are
available through the National Institute of Standards and
Technology (NIST) in the USA. NIST can completely characterize
and verify all major specifications of the 5071A. For information
regarding the various tests available, contact:

A. Time Domain
This is an engineering-level measurement requiring a special test setup. The
test setup must be carefully designed to eliminate all sources of noise. For
more information on how to make this measurement, see NIST Technical
Note 1337 (available from US Government Printing Office, Washington DC.,
USA). This is an excellent theoretical as well as technical reference for this
measurement.
Record the actual reading in the appropriate place in the Performance Test
Record. This completes the performance test.
B. Frequency Domain
This measurement requires the HP/Agilent 3048A or equivalent Phase Noise
Measurement System, a highly specialized test system. In order to perform
properly, this system must contain a reference oscillator with phase noise
characteristics that are equal to or better than the 5071A. Instructions for
performing frequency domain stability tests can be found in the HP/Agilent
3048A system documentation.
Record the actual reading in the appropriate place in the Performance Test
Record.
