(6) Press measuring receiver 27.3 SPCL keys, enter the offset frequency from table
H1, and press the MHz key.
(7) 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.
(8) Note the power meter reading and record it as Power meter reading in table H1
alongside the appropriate test frequency.
(9) Note the measuring receiver reading and record it as Init dB reading in table H1
alongside the appropriate test frequency.
(10) Press the TI BLUE (SHIFT) key, then the SET REF (ZERO) key.
(11) 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 H1 alongside the appropriate test frequency.
(12) Set signal generator No. 1 to the level calculated in (12) above and press the
CALIBRATE key.
(13) 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 H1 alongside the appropriate test
frequency.
(14) Set signal generator No. 1 to the level calculated in (14) above and press the
CALIBRATE key.
(15) Set signal generator No. 1 to the initial level of +6 dBm.
(16) Press 38.2 and SPCL keys and record the displayed value as First RF cal fac in
table H1 alongside the appropriate test frequency.
(17) Press 38.3 and SPCL keys and record the displayed value as Second RF cal fac
(18) Press 38.4 and SPCL keys and record the displayed value as Set ref cal fac in
table H1 alongside the appropriate test frequency.
(19) Repeat steps (3) through (18) for each of the test frequencies in table H1.
(20) Press the FREQ and BLUE (SHIFT) AUTO TUNING keys.
