NOTE
Add variable attenuator error, to AMPLITUDE meter
indication in (32) below.
(32) Set AMPLITUDE mV-RANGE-DB switch to 100 mV. AMPLITUDE meter
will indicate between 68.3 and 72.7 mV (68.7 and 72.7 mV).
(33) Set variable attenuator to 0 dB.
(34) Adjust signal generator amplitude controls for an AMPLITUDE meter
indication of 80 mV.
(35) Set variable attenuator to 10 dB.
NOTE
Add variable attenuator error to
meter
AMPLITUDE
indication in (36) below.
(36) Set AMPLITUDE mV-RANGE-DB switch to 30 mV. AMPLITUDE meter will
indicate between 24.5 and 26.0 mV (24.7 and 25.0 mV).
100 MHz.
(38) Repeat (21) through (36) for 100 MHz.
b. Adjustments
(1) Set AMPLITUDE CHANNEL switch to A and AMPLITUDE mV-RANGE-DB
switch to 300 mV.
NOTE
Ensure equipment is set up in the figure 1 configuration.
(2) Adjust signal generator controls to 100 MHz and adjust amplitude controls for a
measuring receiver indication of 0.0 dB.
(3) Adjust FREQ RANGE-MHz control for a dial indication that includes 100 MHz
and APC UNLOCKED indicator is extinguished.
(4) Adjust A3R5 (fig. 4) for a TI meter indication of 0 dB.
(5) Replace channel A probe with channel B probe in figure 1 equipment setup.
(6) Set AMPLITUDE CHANNEL switch to B.
