d. When indications specified in paragraphs 8 through 13 are not within tolerance,
perform the power supply check prior to making adjustments. After adjustments are made,
repeat paragraphs 8 through 13. Do not perform power supply check if all other parameters
are within tolerance.
e. Unless otherwise specified, all controls and control settings refer to the TI.
7. Equipment Setup
HIGH VOLTAGE is used or exposed during the performance of
this calibration. DEATH ON CONTACT may result if personnel
fail to observe safety precautions. REDUCE OUTPUT(S) to the
minimum after each step within the performance check where
applicable.
a. Position TI controls as listed in (1) through (3) below:
(1) VOLT SET switch (rear panel) to appropriate position (115 V ac).
(2) FREQ SET switch (rear panel) to 50/60.
(3) SELECTOR switch (rear panel) to 115 V ac.
b. Connect power cord from modulator AC OUTPUT (rear panel) to signal generator AC
INPUT (rear panel), using power cord supplied with TI.
c. Connect modulator AC INPUT to autotransformer.
d. Connect autotransformer to 115 V ac source and adjust for 115 V ac output.
e. Set both power switches to ON and allow approximately 30 minutes for equipment to
warm-up and stabilize.
NOTE
Remove protective cover only when necessary to perform required
adjustments.
8. Frequency Accuracy and Stability
a. Performance Check
(1) Connect frequency counter to TI RF OUTPUT connector.
(2) Adjust FREQUENCY GHz control to 7.00 GHz.
(3) Set MODULATION SELECTOR switch to CW.
(4) Set a F control to central "0" position.
(5) Adjust POWER SET control for CAL on the power monitor meter.
(6) Adjust ATTENUATOR control for a 0 dBm indication on DBM/MICROVOLTS dial.
