Functions & Advantages

Accuracy and stability Ensure test reliability

Reliability test usually requires multiple chips to run for a long time under power supply. Take HTOL as an example, the number of samples are at least 231 pieces and the test time is up to 1000 hours. N23020 voltage precision is 0.1mV, long-term stability 40ppm/1000h, voltage ripple noise ≤2mVrms, can effectively ensure the reliability of the user test process all round protection, ensure the safety of instruments and products under test.

Ultra-high integration, saving user investment

In the process of chip R&D, flow sheet and mass production, Usually it is necessary to carry out reliability test on multiple groups of samples. In addition, the leakage current of chip or jointed board is also an important test index. The traditional scheme usually adopts multiple linear power sources with data sampling, which is troublesome to connect and occupies test space. The N23020 integrates up to 16 power channels in a 19-inch 2U chassis to support nA-level current measurement, providing a highly integrated solution for large-scale chip testing.

Fast dynamic response

N23020 is provided fast dynamic response capability, under the full voltage output, the load changes from 10% to 90%, voltage recovery to the original voltage reduction within 50mV time is less then 100μs, to ensure that the voltage or current rise waveform within high speed and no over impulse, to provide stable power supply for the chip under test.

Sequence editing

N23020 supports sequence editing function. Users can set output voltage, output current and single step running time. 100 groups of voltage and current sequences can be customized locally.
