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.
