Low Inductance Impulse Tester Model 19301A

Low Inductance Impulse Tester Model 19301A

Impulse tester compatible with low inductance from 0.1μH to 100μH.

The 19301A supports an applied voltage range of 10Vdc to 1000Vdc and enables high-precision measurements of waveform data acquired through high-speed 200MHz sampling using four types of impulse test judgment methods (waveform area comparison/waveform differential area comparison/waveform flutter detection/waveform second derivative detection). The test range for the test specimen inductance is from 0.1μH to 100μH. For measuring winding components, there are electrical characteristic tests and dielectric strength measurements according to electrical safety standards, as one of the main causes of insulation failure in winding components is rare shorts that occur due to the operating environment. This device can also be used for detecting such rare shorts. Impulse testing is possible from 0.1μH. By using the four-terminal test circuit function, it is ideal for measuring ultra-low inductance coils, chips, power inductance, as well as choke coils and coils with fewer turns. Additionally, contact check measurements, inductance measurements, and voltage compensation functions enable more accurate measurements.

OLED Lifetime Test Device Model 2805B

OLED Lifetime Test Device Model 2805B

DC drive high-precision lifetime testing device for 32CH to 128CH. High-precision current output, element voltage measurement, and brightness measurement using PD.

1. High-precision current output. Correction through current value monitoring is unnecessary. 2. High-precision voltage measurement. High-precision measurement is possible to detect voltage fluctuations caused by a 1°C temperature change in the element. 3. Four-terminal connection. Voltage drops due to connection cables to the DUT are compensated. (For example, a voltage drop of 1Ω for a round trip at 10mA can result in a significant error factor of 10mV.) 4. Noise countermeasures enabling high-precision measurement. By synchronizing the power supply for photometry, suppression of noise from indoor fluorescent light flicker and AC power is achieved. 5. Fully automated lifetime testing is possible with control software for Windows. Measurement values for all 128 channels are collected at 2-second intervals, and the measurement interval can be set in five stages from 2 seconds to 24 hours. (Example: the first 5 minutes at 2-second intervals, the next hour at 30-second intervals, the next 12 hours at 5-minute intervals, the next 24 hours at 10-minute intervals, followed by 60-minute intervals.)
