(27) Insert 10 dB attenuator (fixed) between POINT A (fig. 2) and RF detector A.
(28) Perform steps as listed in (a) through (c) below:
(a) (23) then (24).
(b) (21) then (22).
(c) (25) then (26).
(29) Add current linearity error to previous recorded linearity error in table 3.
Record accumulated linearity error in table 3. Accumulated linearity error sum will be less
than linearity specification listed in table 3.
(30) Replace 10 dB attenuator (fixed) with 20 dB attenuator (fixed) in figure 2
equipment setup.
(31) Repeat (21) through (26) above.
(32) Add current linearity error to previous recorded linearity error in table 3.
Record accumulated linearity error sum in table 3. Accumulated linearity error sum will be
less than linearity specification listed in table 3.
(33) Replace 20 dB attenuator (fixed) with 30 dB attenuator (fixed) in figure 2
equipment setup.
(34) Perform steps as listed in (a) through (c) below:
(a) (23) then (24).
(b) (21) then (22).
(c) (25) then (26).
(35) Add current linearity error to previously recorded linearity error in table 3.
Record accumulated linearity error sum in table 3. Accumulated linearity error sum will be
less than linearity specification listed in table 3.
(36) Insert 10 dB attenuator (fixed) between 30 dB attenuator (fixed) and RF
detector A in figure 2 equipment setup.
