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 (in other words, 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 Adjacent Channel Power Ratio
:READ:ACPower?
Description
Triggers a new adjacent channel power ratio measurement and returns the results: main channel power, lower adjacent channel power, 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 is returned as 5 comma-separated values: main channel power, lower adjacent channel power, upper adjacent channel power, lower alternate channel power, upper alternate channel power.
Syntax:

Read Channel Power Density
:READ:CHPower: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.

NA (query only)
Default Unit

Read Channel Power
:READ:CHPower?
Description
Triggers a new channel power measurement and returns the results. It is a combination of the commands :ABORT; :INITiate; :FETCh:CHPower? The channel power measurement must be active. The current measurement can be queried using :CONFigure?
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 :CONFigure?
Data is returned as 3 comma‑separated values: occupied bandwidth, percent of power, dB down.
Syntax:
:READ:OBWidth?
Cmd Parameter
NA (query only)
Default Unit
For OBW: Hz For Percent of Power: % For dB Down: dB
