Function

Sets/queries multi-tone audio analyzer frequencies/states for each of the 20 tones in the form of a comma-separated list of 20 values. A value (in units of Hz by default) must be entered for each of the 20 tones. An entry of 0 in the list indicates that the state of that tone is set to Off.

The multi-tone audio analyzer frequencies/states can not be set when the SETup:CMAudio:ANALyzer:FREQuency:ALL:GENerator is set to ON.

!Sets multi-tone audio analyzer frequencies for tones 1 to 19 and turns 
!their states to On, and turns off tone 20.

Function

Sets/queries whether to use the specified uplink or downlink audio generator frequencies/states for the multi-tone audio analyzer frequencies/states.

When this setting is On, the analyzer sets its frequencies/states according to the downlink audio generator frequency settings ( SETup:CMAudio:GENerator:FREQuency:DOWNlink:PRESet ) for the downlink measurements (when SETup:CMAudio:MEASurement:MODE is set to DOWNlink), or according to the uplink audio generator frequency settings ( SETup:CMAudio:GENerator:FREQuency:Uplink:ALL[:SVALue] or SETup:CMAudio:GENerator:FREQuency:Uplink:PRESet ) for the uplink measurements (when SETup:CMAudio:MEASurement:MODE is set to UPLink). It is useful if you want to measure the same frequencies that are generating.

When this setting is 'Off', the analyzer will use the frequency list specified by SETup:CMAudio:ANALyzer:FREQuency:ALL[:SVALue] for the multi-tone audio measurements.

Function

Sets/queries the multi-tone audio total level and turns the total level state to ON for the downlink audio generator. It is used in a downlink measurement (see SETup:CMAudio:MEASurement:MODE ). The total level determines the individual tone's level, which will be equally distributed among the tones whose states are on (the tone's state is determined by the SETup:CMAudio:GENerator:FREQuency:DOWNlink:PRESet ).
