Pin View Pane DCPower Section

Use this section of the Pin View pane to specify when you select a pin connected to an NI-DCPower instrument to specify voltage and current options. A green icon next to the DCPower section indicates that the NI-DCPower instrument is forcing a voltage or a current. The pane does not display the switch icon to connect or disconnect the pin when the digital pattern instrument does not support this type of functionality.

Note  

The collapsed DCPower section displays the voltage indicator in the section heading. When you expand the section, the voltage indicator displays below the circuit diagram. The NI-DCPower instrument is always measuring voltage and current when the pane is visible.

Note  

You must install the NI-DCPower driver to access NI-DCPower-related functionality in the Digital Pattern Editor.

• Voltage and Current Indicator — Displays the actual voltage and current. The NI-DCPower instrument always measures the voltage and current on the pin.
• I Range — Specifies the current range to use. Use the pull-down menu to select a valid range. Displays I Level Range when you force a current, I Limit Range when you force a voltage, and I Range when idle.
• V Range — Specifies the voltage range to use. Use the pull-down menu to select a valid range. Displays V Limit Range when you force a current, V Level Range when you force a voltage, and V Range when idle.
• V_F Enable Button — Enables NI-DCPower instrument Force Voltage and disables any other active enable button. Disabling NI-DCPower instrument Force Voltage puts the pin into a high-impedance state until you enable NI-DCPower instrument Force Voltage or enable NI-DCPower instrument Force Current.
• I_C — Specifies the maximum limit for the current at the pin when the NI-DCPower instrument forces voltage to the DUT. This value is enabled when the NI-DCPower instrument is in Force Voltage mode.
• I_F Enable Button — Enables NI-DCPower instrument Force Current and disables any other active enable button. Disabling NI-DCPower instrument Force Current puts the pin into a high-impedance state until you enable NI-DCPower instrument Force Voltage or enable NI-DCPower instrument Force Current.
• V_C — Specifies the maximum limit for the voltage at the pin when the NI-DCPower instrument forces current to the DUT. Enabled only when the NI-DCPower instrument is in Force Current mode.
• Sense—Specifies the method used when collecting output and voltage measurements.
  • Local—Use a single set of connections for output and voltage measurement.
  • Remote—Use two sets of connections for output and voltage measurement.
    

    Note  

    Remote sense measurements are appropriate for high-current applications. Remote sense enables more accurate voltage output and measurements when the output lead voltage drop is significant.
