:FETCh:CNRatio?
Syntax
:FETCh:CNRatio?
Description
Queries the results of C/N ratio measurement.
Remarks
This command is only valid when the C/N ratio measurement in GPSA mode is enabled.
The power unit of the return value is consistent with the current Y-axis unit.
This command will select data from the latest measurement results, and then transmit the data to the
output buffer.
Return Format
The query returns the carrier power, noise power, and C/N ratio (in dB) in scientific notation. They are
separated by commas.
Example
The following query returns -6.048788000e+01,-6.186192000e+01,1.374039000e+00.
:FETCh:CNRatio?
