Obtains the results of the measurement.

This VI transfers the data from the instrument as long as the acquisition status is Acquisition Complete. If the status is either Running or Triggered, this VI waits until the status transitions to Acquisition Complete. If the status is Stopped, this VI returns an error.

Instrument Handle In specifies the session created by the Scope Initialize VI.
Error In describes error conditions that occur before this node runs. This input provides standard error in functionality.
Instrument Handle Out returns a reference to the instrument.
Analog Waveforms returns the analog waveforms acquired by the instrument. This VI returns data from multiple analog channels in the order of lowest channel number to highest channel number. For example, if scope/1 and scope/2 are enabled, Analog Waveforms returns a two-element array in the order of scope/1 and scope/2.

If you configure the Configure Timing VI to sample in Peak Detect mode, this VI returns two waveforms per channel: a minimums waveform and a maximums waveform.
Trigger Time Stamp returns the time when the acquisition is triggered.
Trigger Reason returns how the acquisition is triggered.
Name Value Description
Normal 0 The acquisition is triggered by a normal trigger.
Forced 1 The acquisition is triggered by a forced trigger.
Auto 2 The acquisition is automatically triggered.
Error Out contains error information. This output provides standard error out functionality.
