key, is the standard sweep mode of the
analyzer, in which the sweep is triggered automatically and
continuously and the trace is updated with each sweep.
brings up the conversion menu which converts the measured
data to impedance (Z) or admittance
(Y).
When a conversion
parameter has been defined, it is shown in brackets under the
softkey label. If no conversion has been defined, the softkey

recent calibration data for the displayed parameter. If the
stimulus state has been changed since calibration, the original
state is recalled, and the message “SOURCE PARAMETERS
CHANGED” is displayed.
