as described on page 42.
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*.
*Caution:
To avoid the loss of data, GPIB settings, or current user
instrument states that have not been permanently saved to
non-volatile memory, the MXG should always be powered
down either via the MXG's front panel power button or the
appropriate SCPI command. MXG's installed in rack
systems and powered down with the system rack power
switch rather than the MXG's front panel switch display a
Error -310 due to the MXG not being powered down
correctly.
Deletes any user–generated
calibration data and restores
the factory−supplied
calibration data.
Note
A DC calibration requires the following settings:
• I/Q: On
• Optimized Path: RF Output
• Source: Internal
