Record the MKR A amplitude:
38. Choose the smallest MKR A amplitude in steps 36 and 37.
Record its absolute value:
(For example, if one MKR A amplitude is -82
and the other
is -79
record
This value is S, the third order
suppression.
39. Compute the third order intercept
as follows:
TO1 = P + S/2, where P = input signal power, and S = third order suppression from step 38.
