6.6.1. Alignment

No alignment is needed.

6.6.2. 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 SINAD the volume is increased until

sufficient to measure SINAD. The output level of the analyzer is then adjusted until the

radio audio signal’s SINAD level measures about 12 dB. The current output level is then

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