NOTE
In the tests that follow, ignore error messages displayed by the
measuring receiver.
(11) Set spectrum analyzer sweep time to 50 ms, clear/write trace 1, and set trace 1
to maximum hold.

(15) Set spectrum analyzer for clear/write trace 1, and set trace 1 to maximum hold.
2.5 MHz and a stop frequency of 1.3 GHz.
(17) When sweep is complete, set spectrum analyzer for a marker peak search.
Marker amplitude displayed on spectrum analyzer will be within limits specified in first
row of table 19.
(18) Repeat technique of (14) (e), (f), and (15) through (17) above for remaining TI
special function setting in table 19. Marker amplitude displayed on spectrum analyzer will
be within limits specified in table 19.
