:FETCh:ACPower?
Syntax
:FETCh:ACPower?
Description
Query the results of adjacent channel power measurement.
Explanation
This command is only available when the adjacent channel power measurement is enabled.
The power unit of the return values is the same with the current Y-axis unit.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns 5 values (main channel power, upper channel power as well as the power difference
between the upper channel and main channel (in dBc), the lower channel power as well as the power
difference between the lower channel and the main channel (in dBc)) in scientific notation (separated by
commas).
Example
The query below returns -5.150423E+01,-5.173441E+01, -2.301865E-01,-5.142665E+01,7.757568E-02.
:FETCh:ACPower?
:FETCh:ACPower:LOWer?
Syntax
:FETCh:ACPower:LOWer?
Description
Query the lower channel power of adjacent channel power measurement.
Explanation
This command is only available when the adjacent channel power measurement is enabled.
The power unit of the return value is the same with the current Y-axis unit.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns the lower channel power in scientific notation.
Example
