Phase Noise (Instruments without Option 11)
Check Phase Noise
If Option 11 is not installed in your instrument, use the following procedure
to check the phase noise. If Option 11 is installed in your instrument, use the
preceding procedure. (See page 78,
Phase Noise (Instruments with Option 11)
NOTE.
The intent of the Phase Noise test is to measure the phase noise level of the
instrument. The phase noise speci
fi
cation does not cover residual spurs. If the
speci
fi
c measurement frequency results in measuring a residual spur that is visible
above the noise level, the phase noise speci
fi
cation applies not to the spur but to
the noise level on either side of the spur. Please refer to the Spurious Response
speci
fi
cations. (See Table 20.) Also, refer to the Spurious Response section of this
procedure to determine whether or not a residual spur is within the speci
fi
cation.
(See page 124, Spurious Response.)
