4.13.1. 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 analyzer output
level is then compared against test limits. The final results are written to the log file.
