CalReady, this setting optimizes the calibration based on the type of DUT
being measured. See also: CalReady Properties in

— NonReciprocal (default) An amplifier is a Non-Reciprocal device
because it has gain in the forward direction, and very high loss
(isolation) in the reverse direction. This choice provides the best
correction for non-reciprocal devices, and reasonable correction for
reciprocal devices.
— Reciprocal A reciprocal DUT is a device in which the insertion loss
through the device is equal in both the forward (S21) and reverse
(S12) directions. A cable is a reciprocal device. This choice provides
the best correction for reciprocal devices. However, S11
measurements on non-reciprocal devices will appear to have more
return loss than the non-reciprocal choice.
