No alignment is needed.
6.4.2. 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.
Dual-Band: This test is performed for the lowest RX Test Frequency in each band.
