 If the check box is off, the analyzer prepares the calibration sweep(s) for each individual
measured standard ("Preparing Cal Sweep...") and reduces the number of drive ports to the
required minimum. This can be the fastest method, in particular if the calibration sweeps take
longer than the preparation phase (e.g. due to small bandwidths, a large number of sweep points),
or if many ports are calibrated.
 If the check box is on, each standard involved in an n-port calibration (or in n one-port
calibrations) is measured with n drive ports. The calibration sweep setup is the same for all
standards; no individual preparation phases are required. This speeds up the calibration, provided
that the calibration sweeps are fast compared to the preparation phases.
Due to the similarity of the measurement phases and timing with the later measurement of the
device under test, this calibration method is potentially more accurate than the previous method. If
the sweeps are relatively slow, or if many ports are calibrated, it causes longer calibration times.
Checks on switching to the next dialog
When the Next> button is pressed the analyzer checks the calibration kits and the matching of the
calibration standards and possibly displays a notice box (confirm with OK). This happens:
 If one of the calibration kits is described by ideal kit parameters or typical values.
 If different connector types are defined at the ports but the selected calibration type requires
uniform connectors.
 If a predefined 7-term calibration method TXX (TOM, TRL, TNA, TRM) is selected but one of the
calibration standards is mismatched. A standard is assumed to be mismatched if it is described by
S-parameter data (*.snp file) with a reflection factor > –30 dB.

Compile Calibrations
The second dialog of the calibration wizard appears for user-defined (Other...) calibrations only. It is used
to compile a list of calibration types and physical ports in order to perform all calibrations in a single
measurement sequence. A measurement of a particular standard that is required for different calibration
types can be reused.
