4 ALIGNMENTS
4-1 GENERAL NOTICES:
1. As for indicating antenna input voltage in dB, 0 dB is referenced to 1 nV
unless otherwise specified.
2. Make sure that the T-X150 is properly set for the voltage in your locality.
3. In the alignment procedure charts, the instruction in the SETTING column
at each step is continued from the previous step unless otherwise
specified.

NOTES ON TEST SETUP AND ALIGNMENT PROCEDURE CHART
The relationship between output level indication (dB) of FM SG (signal
generator) and tuner's antenna input power (dBf) under the condition shown
in Fig. 4-1 is as follows: —
A. When the FM SG level indicator shows the open-end output voltage (dB)
dBf = FM SG level indication (dB) — 6.8 dB
FM SG level indication (dB) = dBf + 6.8 dB
