嗨，SMU的输出阻抗在非开尔文连接时通常为0.2欧姆。通常情况下，DUT和电缆阻抗会增加。如果你使用开尔文连接（4线或力和感应连接），由于阻抗是
非常高，输出阻抗小于0.001欧姆（变得非常小）。最好的问候，中野圭介

Hi,
The output impedance of SMU is typically 0.2ohm at non-kelvin connection.
Normally, the DUT and cable impedance will be added.
If you use the kelvin connection (4-wire or force and sense connection), since the sence impedance is very high, the output impedance is less than 0.001 ohm (becomes very small).
Best regards,
