Precision Premier II Ferroelectric Loop-Tester
The Precision Premier II Ferroelectric loop-tester can execute a single pass hysteresis loop in 100μs without interlacing the data acquisition.
Premier II uses a 40MHz clock through a down counter resulting in an effective maximum clock rate of 10MHz. The capture rate for the 18bit ADCs in the system is 2MHz. The maximum hysteresis frequency of the Premier II is 250 kHz. The driver for the Premier II interlaces multiple loops to generate an effective capture rate of 10MHz on hysteresis and a total loop period of 10μs. The Premier II will execute a PUND pulse measurement with pulse widths ranging from 0.5μs to 1s on capacitors with areas ranging from 0.5u2 up to multiple square centimeters. Along with the main setup, it is attached to a high voltage power amplifier (Trek Model 609B-3 is DC stable with an output voltage range from 0 to ±10 kV) via Precision 10KV High Voltage Interface and High Voltage Amplifier.
The Premier II Ferroelectric Test System is driven, and Vision Software analyzes data.
