8.3.6 Sweep Mode
Sweep mode is not available in Setup Tool. This mode is used
primarily as a setup and diagnostic aid. In this mode the instrument will sweep
through a range starting at a user provided Start frequency and incrementing
at desired step size. During the sweep the amplitude is plotted. The sensor’s
temperature, amplitude (arbitrary scale) and phase (degree) at the current
excitation frequency is shown in the data window. The extent of the sweep
depends on the Start frequency, Step size and data points to be plotted as
chosen in
section 8.3.10 on page 8-25 .
Once the sweep begins, the Start and Step input fields cannot be modified until
the sweep is completed normally or interrupted by the user. The user can
choose a single sweep or cycle continuously. A normal sweep plot is shown in
Figure 8-6 .
