10. Center Frequency Accuracy
a. Performance Check
(1) Connect TI CAL OUTPUT to TI RF INPUT.
(2) Press 2 22 GHz, RECALL, 9 keys.
(3) Adjust FREQ ZERO control for a maximum amplitude trace.
(4) Press 2 22 GHz key.
(5) Disconnect TI CAL OUTPUT from TI RF INPUT.
(6) Connect TI RF INPUT to synthesized signal generator No. 1 RF Output.
(7) Connect TI 10 MHz OUT (rear panel) to the synthesized signal generator No. 1
10 MHz REF IN (rear panel).
(8) Set synthesized signal generator No. 1 for an output of 2.000000 GHz at a level
of 0 dBm.
(9) Press TI keys as listed in (a) through (d) below:
CENTER FREQUENCY, 2, GHz.

(d)
(10) Press TI REFERENCE LEVEL and adjust as necessary to place signal peak at
convenient level.
(11) If TI center frequency readout does not fall within limits listed in the first row of
table 4, perform b below.
(12) Repeat technique of (8) through (10) above for remaining center frequencies and
limits specified in table 4, perform b below.
