(8) Press the GOLD (S) TUNED RF LEVEL, 39.9, SPCL, 3.7 SPCL, and 1.9
SPCL keys then press the LOG/LIN key for dBm units.
(9) Note the power meter reading and record it as power meter reading in table E1
alongside the appropriate test frequency.
(10) Note the measuring receiver reading and record it as Init dB reading in table E1
alongside the appropriate test frequency.
(11) Press the TI BLUE (SHIFT) key, then the SET REF (ZERO) key.
(12) Calculate the first cal point using the formula -40 + signal generator No. 1 (No.2)
output level - Init dB reading. (Example -40 dBm + (6 dBm) - (-1 dBm) = -33 dBm). Record
this value, as first cal point in table B1 alongside the appropriate test frequency.
(13) Set signal generator No. 1 to the level calculated in (12) above and press the
CALIBRATE key.
(14) Calculate the second cal point using the formula -80 + signal generator No. 1
output level -40 dBm to result of step (12). (Example -80 dBm + (6 dBm) - (-1 dBm) =
-73 dBm). Record this value, as second cal point in table E1 alongside the appropriate
test frequency.
(15) Set signal generator No. 1 to the level calculated in (14) above and press the
CALIBRATE key.
(16) Set signal generator No. 1 to the initial level of +6 dBm.
(17) Press 38.2 and SPCL keys and record the displayed value as First RF cal fac in
table E1 alongside the appropriate test frequency.
(18) Press 38.3 and SPCL keys and record the displayed value as Second RF cal fac
in table E1 alongside the appropriate test frequency.
(19) Press 38.4 and SPCL keys and record the displayed value as Set Ref cal fac in
table E1 alongside the appropriate test frequency.
(20) Repeat steps (3) through (19) for each of the test frequencies in table E1.
(21) Press the FREQ and BLUE (SHIFT) AUTO TUNING keys.
(23) Press the GOLD(S) TUNED RF LEVEL, 26.1 and SPCL keys.
NOTE
For frequencies below 1.3 GHz proceed to step (26) below.
(24) Press 27.3 SPCL, enter the appropriate offset frequency from table B1, and
press the MHz key. (Ignore the displayed frequency reading.)
(25) Set signal generator No. 2 for an output of +8 dBm and the appropriate offset
frequency from table E1.
(26) Connect TI into figure 7 equipment setup as listed in (a) through (d) below:
