Measurement Jitter
Step 9. Convert the linear standard deviation to Log
10
using
10 * LOG
10
(1+ standard deviation
Lin
)
to give the standard deviation for Y-Factor results with no Averaging.
Enter the result into the Test Record ensuring that the measured value
is within its published specification.
Example:
Standard Deviation = 10 * LOG
10
(1+ standard deviation
Lin
)
=10 * LOG
10
(1+ 0. 011071
Lin
)
= 0.0478dB
