You can use one of two modes for acquiring measurements using an SMU or VPS device in Instrument Studio: Source & Sample, and Sweep.
Source & Sample—Allows multiple channels to source current or voltage. If the device is in a large panel, measured results are plotted to the graph. When you pause the measurements, InstrumentStudio pauses the channel outputs at the last configured level.
Sweep—For a single channel, this mode sweeps through configured current or voltage steps and plots the results on the graph. For multiple channels, this mode sweeps two channels through configured current or voltage steps and plots the results on a graph. A multiple channel sweep acts as a nested loop, where the inner channel executes all of the steps for each step configured in the outer channel. When you stop the measurement in Sweep mode, InstrumentStudio stops both measurements and channel outputs.
Sweep mode is not available on PXI-4110 and PXI-4130 devices.
