Calculate the attenuation error values for this column by subtracting the
values
in column “C” from the values in column
“B”
(B
-
C = D).
4. The values in column “F” result from correcting the expected measurement
value by the amount of attenuator error.
Calculate the values in this column by subtracting the values in column “D”
from the values in column
“E”
(E
-
D =
F).
5. Transfer the values from column “F” in
‘Iable
2-l to column “F” in the
“Performance
Test
Record” for both test ports.
