(28) Press TI keys as listed in (a) and (b) below:
(a) DATA 1.7.
(b) DATA SPCL.
(29) Set spectrum analyzer sweep time to 50 ms, clear/write trace 1, and set trace 1
to maximum hold.
2.5 MHz and a stop frequency of 1.3 GHz.
(31) 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 20.
(32) Repeat technique of (28) through (31) above for remaining TI special function
setting in table 20. Marker amplitude displayed on spectrum analyzer will be within limits
specified in table 20.
