(7) Press measuring receiver 27.3 SPCL keys, enter the offset frequency from table
B1, and
press the
MHz key.
(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 B1
(10) Note the measuring receiver reading and record it as 'Init dB' reading in table
B1 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.
