I/Q Calibration - Agilent Technologies N5181A User Manual

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 DC
calibration and causes the signal generator to revert to the
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.
