Cascading Outputs

Caution  Do not exceed 60 VDC from any terminal to ground when cascading multiple channels on the NI PXI-4130.

Because channel 1 on the NI PXI-4130 is an isolated output, it can be cascaded in series with other output channels to generate larger output voltages. For safety reasons, all terminals must be <60 VDC from ground. Any terminal on an isolated channel can be connected to ground.

The SMU channel on the NI PXI-4130 cannot be used in parallel with other channels to generate larger output currents because it is a four-quadrant supply and may begin to sink current when connected in parallel to another channel with a higher voltage.

Note  Auxiliary power is required for channel 1 output greater than 2 W or 300 mA. Refer to Internal and Auxiliary Power for more information about auxiliary power.

Caution  The NI PXI-4130 does not provide isolation when using CH 0.
