Performance Verification
if the peak is on
a spur, not the noise floor, place the marker on the highest
point of the noise floor.
NOTE. The intent of the DANL test is to measure the average internal noise level
of the instrument. The DANL specification does not cover residual spurs. If the
specific measurement frequency results in measuring a residual spur that is vis ible
above the noise level, the DANL specification applies not to the spur but to the
noise level
on either side of the spur. Please refer to the Spurious Response
specifications. (Se e Table 20.) Also, refer to the Spurious Response section of this
procedure to determine whether or not a residual spur is within the spe cification.
(See page 124, Spurious Response.)
