Configure Operation

Channels Tab

The Channels tab contains a list control with the default channels for the selected logical name. Use the Add and Remove buttons to add new channels and remove existing channels from the list. You can specify whether the power supply outputs a signal for the channel by enabling the channel using the check box within the list control.

• Preserve Existing Channels —When you enable this option, the step adds to or modifies any previously configured channels. When you disable this option, the step deletes all previously configured channels before configuring the specified channels in the list.

The Channels tab for the Configure operation also contains the following channel-specific options:

• Name —The name of the channel. The channel name must be a valid virtual channel name as the IVI configuration for the logical name being used defines. Output Tab

  The Output tab for the Configure operation contains the following channel-specific controls:

  • Voltage Level (V) —The voltage level, in volts, the DC power supply attempts to generate.
  • Output Range Mode —Specifies how to configure the output range of the power supply on a channel.

    Supported Value	Description
    Automatic (-1)	The Voltage Level setting to be used to configure the range of the instrument.
    Use Current Range (0)	The Current Range setting to be used to configure the range of the instrument.
    Use Voltage Range (1)	The Voltage Range setting to be used to configure the range of the instrument.

  • Voltage Range (V) —The maximum voltage value, in volts, of the instrument if Output Range Mode is set to Automatic or Use Voltage Range. Setting a voltage range can invalidate a previously configured current range.
  • Current Range (A) —The maximum current value, in amperes, of the instrument if Output Range Mode is set to Use Current Range. Setting a current range can invalidate a previously configured voltage range.
  Limits Tab

  The Limits tab for the Configure operation contains the following channel-specific controls:

  • Current Limit Behavior —The behavior of the power supply when the output current is equal to or greater than the value of the Current Limit setting.

    Supported Value	Description
    Current Regulate (0)	Indicates the output voltage restriction. The power supply restricts the output voltage so the output current is not greater than the value of the Current Limit setting.
    Current Trip (1)	Indicates the disabling output voltage. The power supply disables the output when the output current is equal to or greater than the value of the Current Limit setting.

  • Current Limit —The output current limit, in amperes. The value of the Current Limit Behavior setting determines the behavior of the power supply when the output current is equal to or greater than the value of the Current Limit setting.
  • OVP Enabled —When you enable this option, the power supply provides overvoltage protection. When this property is set to True , the power supply disables the output when the output voltage is greater than or equal to the value of the OVP Limit setting.
  • OVP Limit —The maximum voltage, in volts, the power supply allows. When the OVP Enabled setting is set to True , the power supply disables the output when the output voltage is greater than or equal to the value of the OVP Limit setting. When the OVP Enabled setting is set to False , the OVP Limit setting does not affect the behavior of the instrument.
  Trigger Tab

  The Trigger tab for the Configure operation contains the following channel-specific controls:

  • Trigger Source —The trigger source. After you call Initiate, the power supply waits for a trigger event from the source you specify with the Trigger Source setting. After a trigger event occurs, the power supply changes the voltage level to the value of the Triggered Voltage Level setting and the current limit to the value of the Triggered Current Limit setting.

    Supported Value	Description
    Software (2)	Indicates the power supply waits for the Send Software Trigger operation to execute before changing the output signal.
    ECL0 (11)	Indicates the power supply waits for a trigger on the ECL 0 line before changing the output signal.
    ECL1 (12)	Indicates the power supply waits for a trigger on the ECL 1 line before changing the output signal.
    External (1)	Indicates the power supply waits for an external trigger before changing the output signal.
    Immediate (0)	Indicates the power supply does not wait for a trigger before changing the output signal.
    PXI Star (13)	Indicates the power supply waits for a trigger on the PXI STAR line before changing the output signal.
    RTSI0 (14)	Indicates the power supply waits for a trigger on the RTSI 0 line before changing the output signal.
    RTSI1 (15)	Indicates the power supply waits for a trigger on the RTSI 1 line before changing the output signal.
    RTSI2 (16)	Indicates the power supply waits for a trigger on the RTSI 2 line before changing the output signal.
    RTSI3 (17)	Indicates the power supply waits for a trigger on the RTSI 3 line before changing the output signal.
    RTSI4 (18)	Indicates the power supply waits for a trigger on the RTSI 4 line before changing the output signal.
    RTSI5 (19)	Indicates the power supply waits for a trigger on the RTSI 5 line before changing the output signal.
    RTSI6 (20)	Indicates the power supply waits for a trigger on the RTSI 6 line before changing the output signal.
    TTL0 (3)	Indicates the power supply waits for a trigger on the TTL 0 line before changing the output signal.
    TTL1 (4)	Indicates the power supply waits for a trigger on the TTL 1 line before changing the output signal.
    TTL2 (5)	Indicates the power supply waits for a trigger on the TTL 2 line before changing the output signal.
    TTL3 (6)	Indicates the power supply waits for a trigger on the TTL 3 line before changing the output signal.
    TTL4 (7)	Indicates the power supply waits for a trigger on the TTL 4 line before changing the output signal.
    TTL5 (8)	Indicates the power supply waits for a trigger on the TTL 5 line before changing the output signal.
    TTL6 (9)	Indicates the power supply waits for a trigger on the TTL 6 line before changing the output signal.
    TTL7 (10)	Indicates the power supply waits for a trigger on the TTL 7 line before changing the output signal.

  • Triggered Current Limit —The value, in amperes, to which the power supply sets the current limit after a trigger event occurs. After you call Initiate, the power supply waits for a trigger event from the source you specify with the Trigger Source setting. After a trigger event occurs, the power supply sets the current limit to the value of the Triggered Current Limit setting. After a trigger occurs, the value of the Current Limit setting reflects the new value to which the current limit has been set.
  • Triggered Voltage Level —The value, in volts, to which the power supply sets the voltage level after a trigger event occurs. After you call Initiate, the power supply waits for a trigger event from the source you specify with the Trigger Source setting. After a trigger event occurs, the power supply sets the voltage level to the value of the Triggered Voltage Level setting.

    After a trigger occurs, the value of the Voltage Level setting reflects the new value to which the voltage level has been set.
