This set of commands combines the ABORt, INITiate and FETCh commands. It aborts any current triggering sequence and sets the trigger state to idle. It then initiates a new active measurement (i.e. begins the collection of new data). When the measurement is complete, it returns the result. These commands do not switch to another measurement.
To get the current measurement data, use the FETCh command.
:READ:ACPower?
Title
Read Adjacent Channel Power Ratio
Description
Triggers a new adjacent channel power ratio measurement and returns the results: main channel power, lower adjacent and upper adjacent channel power. It is a combination of the commands :ABORT; :INITiate; :FETCh:ACPower? The channel power measurement must be the active measurement (specified by the command :CONFigure:ACPower). The current measurement can be queried using the command :CONFigure?
Data are returned as five comma-separated values: main channel power, lower adjacent channel power, upper adjacent channel power, lower alternate channel power, upper alternate channel power.

Title
Read Channel Power Density
Description
Triggers a new channel power measurement and returns the channel power density result. It is a combination of the commands :ABORT; :INITiate; :FETCh:CHPower:DENSity? It returns only the channel power density, not the channel power. Use the command :READ:CHPower? to get both channel power and channel power density. The channel power measurement must be the active measurement (specified by :CONFigure:CHPower). The current measurement can be queried using :CONFigure? command.
Default Unit

Title
Read Channel Power/Density
Description
Triggers a new channel power measurement and returns the results: channel power and channel power density. It is a combination of the commands :ABORT; :INITiate; :FETCh:CHPower? The channel power measurement must be the active measurement (specified by the command :CONFigure:CHPower). The current measurement can be queried using the command :CONFigure?
Data are returned as two comma-separated values: channel power, channel power density.
Triggers a new occupied bandwidth measurement and returns the results: occupied bandwidth, percent of power and dB down. It is a combination of the commands :ABORT; :INITiate; :FETCh:OBWidth? The occupied bandwidth measurement must be the active measurement (specified by :CONFigure:OBWidth). The current measurement can be queried using the :CONFigure?
Data are returned as three comma-separated values: occupied bandwidth, percent of power, dB down.
Default Unit
For OBW:NHz For Percent of Power:N% For dB Down:NdB
