(April 18 2013)



Observed signal levels:

 none         DUT831
 11.4653     11.2063
 11.4647     11.2066
 11.4645     11.2057

Averages
 11.4649     11.2062

Standard deviations of individual measurements
 0.00037      0.00046

Insertion loss 0.2587 dB
Standard deviation on insertion loss 0.00096

Error limits (3 sigma) +/- 0.00096 dB

This is a repeated measurement. The first one
had a standard deviation that was much larger than normal.

The result on the insertion loss was nearly indentical
which was probably a coincidence, one would expect
a discrepancy that would have been about 10 times larger.

The evaluation of the first measurement is included below.
