(31) Repeat technique of (29) through (30) above for remaining signal generator
frequency settings listed in table 7.
(32) Reverse the output ports connections of the power splitter.
(33) Repeat technique of (29) through (30) above and record TI indication under TI
indications No. 2 column in table 7.
NOTE
Refer to table 7 for (34) below.
(34) Add TI indications No. 1 value to TI indications No. 2 value and divide the sum
by two. Record results in TI indications average column. Results recorded in TI indications
average column will be within the limits specified in the minimum-maximum columns of
(35) Repeat (34) above for each row listed in table 7.
b. Adjustments
(1) Adjust R233 (fig. 2) for ME-526/USM (Boonton, Model 92BD with serial number
2890 and below) (fig. 3 for Boonton, Model 92B) for a multimeter indication between -0.01
and +0.01 V dc (ideal 0.00 V dc) (R).
(2) Adjust R353 (fig. 2) for ME-526/USM (Boonton, Model 92BD with serial number
2890 and below) (fig. 3 for Boonton, Model 92B) for a multimeter indication between 9.9 and
10.1 V dc (ideal 10.0 V dc) (R).
(3) Adjust calibrator controls for an output of 1.0 V ac and adjust R303 (fig. 2) for
ME-526/USM (Boonton, Model 92BD with serial number 2890 and below) (fig. 3 for
Boonton, Model 92B) for a TI indication between 0.97 and 1.03 mV (ideal 1.00 mV) (R).
(4) Adjust calibrator controls for an output of 3.0 V ac and adjust R308 (fig. 2) for
ME-526/USM (Boonton, Model 92BD with serial number 2980 and below) (fig. 3 for
Boonton, Model 92B) for a TI indication between 2.91 and 3.09 mV (ideal 3.00 mV) (R).
(5) Adjust calibrator controls for an output of 10.0 V ac and adjust R318 (fig. 2) for
ME-526/USM (Boonton, Model 92BD with serial number 2890 and below) (fig. 3 for
Boonton, Model 92B) for a TI indication between 9.7 and 10.3 mV (ideal 10.0 mV) (R).
