PXI-6704 Analog Output Card Increasing Current Sourcing on Voltage

[jquach2010]

I want to run 0-10V across a resistor network of 20ohms, because I want to stimulate the voltage sensing on the terminals.  The PXI-6704 is rated as +/- 10mA.  How would I be able to increase the current sourcing to 500mA?  Can I place a bench power supply in parallel with the PXI card?

You need an amplifier/buffer.

Some bench power supplys have a control voltage input....  however you can use it to supply a power OP ...

is just one that pops up
