The optional Chamber Task measures the Pulse Polarization response and Small Signal Capacitance of a Pyroelectric material that is being heated and/or cooled within a thermal chamber, on a hot chuck or in a furnace. From these measurements the Spontaneous Polarization Pr(q) and the Dielectric Constant er(q) are computed. These are then combined to determine the Electrical Displacement D(q) as a function of the temperature q.
The Dielectric Constant, the Spontaneous Polarization, the Displacement, the small signal capacitance and all pulse polarization measurements may be plotted in any combination. These may be plotted as a function of the temperature q or the change in temperature from sample point to sample point. The derivatives of Pr(q) and er(q) may also be plotted with respect to the change in temperature. All data may be printed or exported to a Text or Excel file
