Frequency Span Accuracy
a. Performance Check
(1) Press TI 2-22 GHz key.
(2) Connect TI RF INPUT to signal generator RF output connector.
(3) Connect TI 10 MHz OUT (rear panel) to signal generator external reference in
connector (rear panel).
(4) Set the signal generator for an output frequency of 40 MHz at a 10 dBm level.
(5) Press TI keys as listed in (a) and (b) below:
(a) CENTER FREQUENCY, 40, MHz.
(b) FREQUENCY SPAN, 20, kHz.
(6) Change signal generator output frequency to 39.992 MHz (table 5 low frequency).
(7) Press TI MARKER NORMAL, PEAK SEARCH.
and change signal generator output frequency to
(8) Press TI MARKER
40.008 MHz (table 5 high frequency).
(9) Press TI PEAK SEARCH.
(10) TI MARKER
frequency indication on TI display will indicate within limits
specified in the first row of table 5.
(11) Repeat technique of steps (5) (b) through (10) above for remaining signal
generator frequencies and TI frequency spans listed in table 5. TI MARKER frequency
indications will indicate within limits specified in table 5.
