PXIe 4139 slew rates

[srinivas1997]

Hello,

Does the PXIe 4139 card have the capability to control the ramp up/down of the voltage and current? For example, to start at 100mA and ramp down to 0mA at a rate of 18 A/s.

Thanks.

As far as I have used the 4139, it has a programmable output resistance but no control over slew rate whatsoever.

Is there a specific vi/driver that would be used to program the output? And if so, what is it?

You can use the property node with typical niDCPower programming to set the output resistance
