(10) Set AMPLITUDE CHANNEL switch to A.
(11) Adjust signal generator frequency to 1 MHz and amplitude controls for a
measuring receiver indication of 0.0 dB.
(12) Adjust FREQ RANGE-MHz control for a dial indication that includes 1 MHz
and APC UNLOCKED indicator is extinguished.
(13) Replace channel A probe with channel B probe in figure 1 equipment setup.
(14) Set AMPLITUDE CHANNEL switch to B.
(15) Adjust A4R5 (fig. 4) for an AMPLITUDE meter indication of approximately -0.2 dB.
(16) Replace channel B probe with channel A probe in equipment setup.
(17) Set AMPLITUDE CHANNEL switch to A.
(18) Adjust A3R5 (fig. 4) for an AMPLITUDE meter indication of approximately
-0.2 dB.
(19) Repeat (1) through (9) above and allow a tolerance between -0.2 and +0.2 dB
before making any adjustments.
NOTE
If adjustments were made in (19) above, then (10) through (18)
above must be repeated.
(20) Adjust signal generator controls for 1000 MHz and adjust amplitude controls for
a measuring receiver indication of 0.0 dBm.
(21) Set AMPLITUDE CHANNEL switch to A and AMPLITUDE mV-RANGE-DB
switch to 300 mV.
(22) Adjust FREQ RANGE-MHz control for a dial indication that includes 1000 MHz
and APC UNLOCKED indicator is extinguished.
(23) If AMPLITUDE meter indication is not between 188 and 259 mV, adjust A3R20
(fig. 4) for an intolerance indication between 188 and 259 mV (R).
(24) Set AMPLITUDE mV-RANGE-DB switch to +10 dB.
(25) Adjust signal generator amplitude controls for a measuring receiver indication of
+10.0 dBm.
