4.9.1 Necessary Deviation adjustment item for each signaling and mode
The following shows the necessary adjustment items for each signaling deviation
For example, in a case of the signaling "QT (Analog Wide)", this signaling deviation is composed of three elements [Balance, Maximum
Deviation (Analog Wide) and QT Deviation (Analog Wide)]. Therefore, it is necessary to adjust Balance and Maximum Deviation
(Analog Wide) before adjusting QT Deviation (Analog Wide).
• Balance is common with all deviation adjustments as above. If Balance (Transmitter Section 9) has already adjusted, please skip
Step 1 and adjust from Step 2.
• Maximum Deviation (Analog Wide) is common with all the analog signaling deviations. If Balance and Maximum Deviation (Analog
Wide) (Transmitter Section 10) have already adjusted, please skip Step 2 and adjust from Step 3.
