I/Q Calibration
I/Q Calibration
Use the I/Q calibration for I and Q signal corrections. What aspects of the I and Q signal is corrected
depends on whether the signal is internally or externally generated.
When you perform an I/Q calibration, that calibration data takes precedence over the
factory- supplied calibration data. The calibration routines improves performance that may degrade
over time or due to temperature changes.

DC optimizes the I/Q performance for the current
instrument settings, and typically completes in several
seconds. Changing any instrument setting except for I/Q
adjustments after performing a DC calibration voids the D
C
calibration and causes the signal generator to revert to th
e
factory−supplied calibration data.
Presetting the instrument or cycling power is equivalent to
pressing Revert to Default Cal Setting.
User provides a quicker calibration when a full calibration
is not required. You can limit the calibration by specifying
the calibration start and stop frequencies.
When you limit the calibration to less than the instrument’
s
full frequency range, the factory−supplied calibration data
is used for the rest of the range.
Information is retained through a preset or power cycle.
Full takes 5 minutes, executing measurements over the
instrument’s entire frequency range.
Information is retained through a preset or power cycle.

calibration data and restores
the factory−supplied
calibration data.
