:FETCh:OBWidth:OBWidth:FERRor?
Syntax
:FETCh:OBWidth:OBWidth:FERRor?
Description
Query the transmit frequency error.
Explanation
This command is only available when the occupied bandwidth measurement is enabled.
This command will select data from the latest measurement results and transmit the data to the output
buffer.
Return Format
The query returns the transmit frequency error in integer and the unit is Hz.
Example
The query below returns 20000.
:FETCh:OBWidth:OBWidth:FERRor?
:FETCh:TOIntercept?
Syntax
:FETCh:TOIntercept?
Description
Query the results of TOI measurement.
Explanation
This command is only available when the TOI measurement is enabled.
The amplitude 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 the measurement results of TOI in the following format:
the Base Lower frequency (Hz), amplitude, the Base Upper frequency (Hz), amplitude, the 3rd Order Lower
frequency (Hz), amplitude, intercept, the 3rd Order Upper frequency (Hz), amplitude, intercept.
Example
The query below returns
1500450000,-8.131735E+01,1500450000,-8.131735E+01,1500450000,-8.131735E+01,-8.131735E+01,1
500450000,-8.131735E+01,-8.131735E+01.
