PPMU Measure
Instructs the PPMU to measure voltage or current.
This node can be called to take a voltage measurement even if the pin node is not set to PPMU.
Inputs/Outputs
session in
Instrument session obtained from the niDigital Initialize with Optionsnode.
channel list
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.
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.
Site Considerations and Syntax
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 node ignores pins that are not mapped to the digital pattern instrument.
measurement type
Parameter that specifies whether the PPMU measures voltage or current from the DUT.
| Current | The PPMU measures current from the DUT. | |
| Voltage | The PPMU measures voltage from the DUT. |
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error
session out
Handle that identifies the session in all subsequent NI-Digital node calls.
measurements
The returned array of measurements in the order you specify in the channel list .
If a site is disabled, the node does not return data for that site. Use the niDigital Sort Pin Results By Site (DBL) node to order and combine the data to match the channel list . You can also use the niDigital Get Results Pin Map Information node to obtain a sorted list of returned sites and channels.
error out
Error information.
The node produces this output according to standard error behavior.
