NI-DCPower includes one option for stopping generation on PXI-4110 channels and returning the channels to a known state.

Option How To Description
Disabling the output Set the Output Enabled property to False Generates 0 V on a channel. ±2% of the current limit range presently configured for the channel remains on the channel.
Call the niDCPower Reset Device VI Disables power generation, resets all properties included in a session to their default values, clears errors, commits the instrument properties, and leaves the instrument in the Uncommitted state.

Disabling the Output

The output of a channel is enabled by default when the channel enters the Running state. However, you can programmatically enable and disable the output channel(s) of the PXI-4110.

When you disable the output of the PXI-4110, the instrument is configured to output a DC voltage at 0 V with current limits at ±2% of the presently configured current limit range in, unless otherwise noted, a low-impedance state.

When you enable a previously disabled channel, levels and limits are applied to the channel depending on the output function as follows:

  • Voltage output functions—The programmed voltage level and current limit are applied to the channel(s)
  • Current output functions—The programmed current level and voltage limit are applied to the channel(s)

    • You can use the Configure Output Enabled function to toggle the output of an instrument.

    Tip To ensure the output is disabled on the hardware, after using the Configure Output Enabled function or Output Enabled property, use the Wait For Event With Channels function. This function waits for the Source Complete event before calling the Abort With Channels function to transition the session out of the Running state.
