The MG362x1A firmware includes internal diagnostics that self test the instrument. These self-test diagnostics perform a brief functionality test of most of the PCBs and other internal assemblies. For more on performing self test and viewing the results, see Self-Test Messages.
Caution
During self test with RF OUTPUT set to ON, the output power level is set to 0 dBm. Always disconnect sensitive equipment from the unit before performing self test.
