READ Commands

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 will not switch to another measurement.

To get the current measurement data, use the FETCh command.

Read Adjacent Channel Power Ratio

:READ:ACPower?

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 :CONFigure:ACPower). The current measurement can be queried using :CONFigure?

Data is returned as 3 comma-separated values: main channel power, lower adjacent channel power, upper adjacent channel power.

:READ:ACPower? :CONFigure

 

Read Channel Power/Density

:READ:CHPower?

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 :CONFigure:CHPower). The current measurement can be queried using :CONFigure?

Data is returned as 2 comma-separated values: channel power, channel power density.

Read Channel Power

:READ:CHPower:CHPower?

Triggers a new channel power measurement and returns the channel power result.

It is a combination of the commands :ABORT;:INITiate;:FETCh:CHPower:CHPower?

It returns only the channel power, not the channel power density. Use :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?

Default Units:	Current amplitude units
See Also:	:READ:CHPower? :READ:CHPower:DENSity? :CONFigure

 

Read Channel Power Density

:READ:CHPower:DENSity?

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 :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?

Default Units:	Current amplitude units
See Also:	:READ:CHPower? :READ:CHPower:CHPower? :CONFigure

 

Read Occupied Bandwidth

:READ:OBWidth?

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.

Default Units:	For OBW: Hz For Percent of Power: % For dB Down: dB
See Also:	:CONFigure

 

Read Tracking Generator Absolute Statistics

:READ:TGENerator:ABSStats?

Triggers a new tracking generator absolute statistic measurement and returns the results. It is a combination of the commands :ABORT;:INITiate;:FETCh:TGENerator:ABSStats?

The tracking generator absolute statistic measurement must be the active measurement (specified by :CONFigure:TGENerator ABSStats). The current measurement can be queried using :CONFigure?

Data is returned as 3 comma-separated values: absolute max power, absolute min power, absolute average power.

Required Options:

20

 

Read Tracking Generator Relative Statistics

:READ:TGENerator:RELStats?

Triggers a new tracking generator relative statistics measurement and returns the results. It is a combination of the commands :ABORT;:INITiate;:FETCh:TGENerator:RELStats?

The tracking generator S21 Insertion Loss relative statistic measurement must be the active measurement (specified by :CONFigure:TGENerator RELStats). The current measurement can be queried using :CONFigure?

Data is returned as 3 comma-separated values: relative max power, relative min power, relative average power.

Required Options:

20
