b. Select appropriate paragraph listed below for TI being calibrated:
(1) Paragraph 8 for TI with frequency range between 300 MHz and 18 GHz.
(2) Paragraph 9 for TI with frequency range between 18 and 40 GHz.
c. Energize equipment and allow sufficient time for warm-up and stabilization.
8. Frequency Accuracy (300 MHz to 18 GHz)
a. Performance Check
(1) Determine correct synthesized signal generator connection in figure 1 using TI
first frequency setting in table selected in 7 a above.
(3) Set TI frequency dial to first frequency setting in table selected in 7 a above.
(4) Adjust synthesized signal generator RF output controls for a convenient
indication on power meter.
(5) Adjust synthesized signal generator frequency controls for a maximum dip
(decrease) in power meter indication (for some TI's, power meter indication will peak
(increase)).
