FTTD-5000B type variable temperature ferroelectric tester
Key words: ferroelectric, hysteresis loop, pulse, leakage, IV
FTTD-5000B variable temperature ferroelectric tester is an extensible and flexible variable temperature ferroelectric test system, and it is also a domestic ferroelectric material performance test equipment that can replace TF Analyzer 2000 ferroelectric analyzer produced by aixACCT company of Germany. It can be widely used in the research of various ferroelectric/piezoelectric/pyroelectric films, thick films, bulk materials and electronic ceramics, ferroelectric sensors/actuators/memory and other fields.
First, the main product performance:
1. The test system consists of a master controller, high voltage amplifier, variable temperature comprehensive test platform (with ferroelectric test box) or high and low temperature probe platform (with high voltage probe), computer and system software.
2, the master integrated programmable waveform generator, built-in drive voltage, charge integrator, programmable amplifier, analog-digital converter, communication bus and other functions,
3, the master provides extended external high voltage amplifier interface, can expand ±5 kV or ±10 kV high voltage amplifier.
4. The system software includes visual data acquisition and management functions. During testing, hysteresis, pulse, leakage, IV and other performance tests can be realized without changing the connection of test samples.
5. The ferroelectric performance test of this test system adopts the measurement method based on virtual ground mode. Compared with the traditional Sawyer-Tower mode, this circuit eliminates the external capacitor, which can reduce the influence of parasitic elements.
6. The test accuracy of this circuit depends only on the accuracy of the integrator’s integral capacitance, which reduces the impact on the test, is easy to calibrate and calibrate, and can achieve high measurement accuracy.
Two, ferroelectric parameter test main performance indicators:
1, external 5 kV high voltage amplifier (can be extended to 10 kV) (domestic, imported are applicable);
2. Dynamic hysteresis loop test frequency range 0.01Hz ~ 5kHz;
3, maximum charge resolution: 10 mC (scalable);
4, fatigue test frequency 300 kHz (amplitude 10 Vpp, load capacitance 1 nF);
5, leakage current measurement range 1 pA ~ 20 mA (extensible), resolution 0.1pA;
6, equipped with high voltage breakdown protection module;
7, temperature range: -160℃ ~ 260℃.
