(10) Using TUNE KNOB, tune the test instrument to 2 GHz.
(11) Readjust A1A2A2R29 (fig. 7) for a measuring receiver indication of 3.0 dBm.
(12) Tune the test instrument from 2 to 6.6 GHz. Verify that the output level stays
within 1 dB of -3 dBm.
(13) Repeat (8) through (12) above until level stays within 1 dB of -3 dBm or until no
further improvement can be made.
(14) Press TI RCL 2.
(15) Using TUNE KNOB, tune the test instrument from 6.600002 to 12.99902 GHz.
Record minimum and maximum measuring receiver indications and frequencies where
they occur.
(16) Adjust A1A8R82 (fig 8) to minimize difference between minimum and maximum
power indications (R).
NOTE
If minimum and maximum output power levels are more than
1.5 dB from 3 dBm, repeat the entire adjustment procedure
until measuring receiver indicates within 1.5 dB of -3 dBm.
(17) Press TI SWEEP MODE OFF, FREQ INCR, 2, 0, 0, and MHz keys.
(18) Verify the measuring receiver indicates 3 dBm 0.2 dBm.
Readjust
A1A2A2R29 (fig. 7) as necessary for best compromise.
(19) Using TUNE KNOB, tune the test instrument from 2 to 12.2 GHz. Verify that
the difference between the minimum and maximum power indications are equal to or less
than 3 dB.
(20) Press TI RCL and 3 keys.
