Q Offset

Press this softkey to enter an origin offset voltage for internally-generated or
externally-applied quadrature-phase signals. Enter the value as a percentage of
full scale (500 mV). The range of values allowed is

−

100% to +100%. Change the

origin offset to adjust out imperfections in the quadrature-phase signal or to
introduce calibrated impairments. Set the origin offset as desired and then toggle
the

Revert to Default Cal Settings

Press this softkey to restore the original factory calibration data for the internal
I/Q modulator. The latest calibration data from the user calibration is discarded.
Although the factory calibration data may not be optimized for the signal
generator’s present status, the data can be used as a starting point if the current
data is lost (if the I/Q calibration is unable to execute).
