NI DIGITAL PATTERN DRIVER PPMU Configuration Functions

PPMU Configuration Functions

• niDigital_PPMU_ConfigureOutputFunction
• niDigital_PPMU_ConfigureApertureTime

niDigital_PPMU_ConfigureOutputFunction

Configures to source DC voltage or DC current from the PPMU.

You must call the niDigital_PPMU_Source function for changes to the PPMU configuration to take effect, even if the PPMU is already sourcing.

C Function Prototype: ViStatus niDigital_PPMU_ConfigureOutputFunction (ViSession vi, ViConstString channelList, ViInt32 outputFunction)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
channelList	List of channel names or list of pins. Do not pass a mix of channel names and pin names. An empty string denotes all digital pattern instrument channels. Pin names and pin groups apply to all enabled sites, unless the pin name explicitly specifies the site. You can specify a pin in a specific site using the form siteN/pinName, where N is the site number. This function ignores pins that are not mapped to the digital pattern instrument. Specify channel names using the form PXI1Slot3/0,2-3 or PXI1Slot3/0,PXI1Slot3/2-3, where PXI1Slot3 is the instrument resource name and 0, 2, 3 are channel names. To specify channels from multiple instruments, use the form PXI1Slot3/0,PXI1Slot3/2-3,PXI1Slot4/2-3. The instruments must be in the same chassis.
outputFunction	Parameter that configures the operation to use for the channels or pins you specify. - NIDIGITAL_VAL_DC_VOLTAGE (1300): Specifies the output function to DC Voltage. - NIDIGITAL_VAL_DC_CURRENT (1301): Specifies the output function to DC Current.

Return value: Reports the status of the operation.

niDigital_PPMU_ConfigureApertureTime

Configures the aperture time for a PPMU measurement on the specified channel(s).

C Function Prototype: ViStatus niDigital_PPMU_ConfigureApertureTime (ViSession vi, ViConstString channelList, ViReal64 apertureTime, ViInt32 units)

Parameter	Description
vi	The specified instrument session the niDigital_init or niDigital_InitWithOptions function returns.
channelList	List of channel names or list of pins. Do not pass a mix of channel names and pin names. An empty string denotes all digital pattern instrument channels. Pin names and pin groups apply to all enabled sites, unless the pin name explicitly specifies the site. You can specify a pin in a specific site using the form siteN/pinName, where N is the site number. This function ignores pins that are not mapped to the digital pattern instrument. Specify channel names using the form PXI1Slot3/0,2-3 or PXI1Slot3/0,PXI1Slot3/2-3, where PXI1Slot3 is the instrument resource name and 0, 2, 3 are channel names. To specify channels from multiple instruments, use the form PXI1Slot3/0,PXI1Slot3/2-3,PXI1Slot4/2-3. The instruments must be in the same chassis.
apertureTime	The measurement aperture time for the PPMU.
units	Units of the measurement aperture time. - NIDIGITAL_VAL_SECONDS (2100): Specifies the aperture time in seconds.

Return value: Reports the status of the operation.
