IviScope Configure Acquisition Type
IviScope Base Capability Group
This VI configures how the oscilloscope acquires data and how it fills the waveform record.
 |
instrument handle The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
acquisition type Specify the manner in which you want the oscilloscope to acquire data and fill the waveform record. The driver sets the IviScope Acquisition Type property to this value.
Defined Values: IVISCOPE_VAL_NORMAL—Sets the oscilloscope to the normal acquisition mode. The oscilloscope acquires one sample for each point in the waveform record. The oscilloscope can use real-time or equivalent-time sampling. IVISCOPE_VAL_PEAK_DETECT—Sets the oscilloscope to the peak-detect acquisition mode. The oscilloscope oversamples the input signal and keeps the minimum and maximum values that correspond to each position in the waveform record. The oscilloscope uses only real-time sampling. IVISCOPE_VAL_HI_RES—Sets the oscilloscope to the high-resolution acquisition mode. The oscilloscope oversamples the input signal and calculates an average value for each position in the waveform record. The oscilloscope uses only real-time sampling. IVISCOPE_VAL_ENVELOPE—Sets the oscilloscope to the envelope acquisition mode. The oscilloscope acquires multiple waveforms and keeps the minimum and maximum voltages it acquires for each point in the waveform record. You specify the number of waveforms the oscilloscope acquires with the IviScope Configure Number of Envelopes [MmW] VI. The oscilloscope can use real-time or equivalent-time sampling. IVISCOPE_VAL_AVERAGE—Sets the oscilloscope to the average acquisition mode. The oscilloscope acquires multiple waveforms and calculates an average value for each point in the waveform record. You specify the number of waveforms the oscilloscope acquires with the IviScope Configure Number of Averages [AA] VI. The oscilloscope can use real-time or equivalent-time sampling. Default value: IVISCOPE_VAL_NORMAL |

Note When you set this parameter to IVISCOPE_VAL_ENVELOPE or IVISCOPE_VAL_PEAK_DETECT, the oscilloscope acquires minimum and maximum waveforms. To retrieve the minimum and maximum waveforms, use the IviScope Read Min Max Waveform [MmW] and IviScope Fetch Min Max Waveform [MmW] VIs. |

error in (no error) The error in cluster can accept error information wired from VIs previously called. Use this information to decide if any functionality should be bypassed in the event of errors from other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
 |
instrument handle out The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
error out The error out cluster passes error or warning information out of a VI to be used by other VIs.
The pop-up option Explain Error (or Explain Warning) gives more information about the error displayed. |
