No alignment is needed.

6.5.2. Test

The analyzer is setup as specified in this section’s Analyzer Configuration table. The

radio is placed into Test Mode at the lowest RX Test Frequency. The radio audio output

level is tested and if insufficient to measure distortion the volume is increased until

sufficient to measure distortion. The audio signal’s distortion level is then measured and

compared to test limits. The final results are written to the log file.
