(48) Press TI keys as listed in (a) and (b) below:
(a) DATA 1.2.
(b) DATA SPCL.
(49) 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.
(51) 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 21.
(52) Repeat technique of (41) through (44) above for remaining TI special function
setting in table 21. Marker amplitude displayed on spectrum analyzer will be within limits
specified in table 21.

In the following steps, ignore the RECAL and UNCAL
annunciators and error messages.
(1) Connect calibrator WIDEBAND output to piston attenuator input (do not use
wideband 50 Ω load) and connect piston attenuator output to TI INPUT 50 Ω (do not use
sensor module).
(2) Set piston attenuator to 20 dB.
(3) Set calibrator for a wideband output frequency of 30 MHz at a level of 22.461 dBm.
