(4) Set MV-RANGE-DB switch to mV settings listed in table 3.
(5) Adjust signal generator amplitude controls for TI full scale AMPLITUDE meter
indication (selected in (4) above).
(6) Configure measuring receiver to measure mV rms.
(7) Adjust FREQ RANGE-MHz control so that APC UNLOCKED light goes out
with range setting including measurement frequency. If measuring receiver indications are
not within limits listed in table 3, perform b below.
+2.55 and -6.9 dBm settings.
NOTE
Perform (9) through (13) below for table 3 signal generator
amplitude settings of -17.4 to -66.9 dBm.
(9) Adjust signal generator amplitude controls for amplitude dBm settings listed in
(10) Set MV-RANGE-DB switch to mV settings listed in table 3.
