IviScope Configure Number of Envelopes
IviScopeMinMaxWaveform Capability Group [MmW]
When you set the acquisition type to IVISCOPE_VAL_ENVELOPE, the oscilloscope acquires multiple waveforms. After each waveform acquisition, the oscilloscope keeps the minimum and maximum values it finds for each element in the waveform record. This VI configures the number of waveforms the oscilloscope acquires and analyzes to create the minimum and maximum waveforms. After the oscilloscope acquires as many waveforms as you specify, it returns to the Idle state.
 |
Note Set the acquisition type to IVISCOPE_VAL_ENVELOPE before you call this VI. To set the acquisition type, call the IviScope Configure Acquisition Type VI. |

instrument handle The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |

number of envelopes When you set the acquisition type to IVISCOPE_VAL_ENVELOPE, the oscilloscope acquires multiple waveforms. After each waveform acquisition, the oscilloscope keeps the minimum and maximum values it finds for each point in the waveform record. This parameter specifies the number of waveforms the oscilloscope acquires and analyzes to create the minimum and maximum waveforms. The driver sets the IviScope Number of Envelopes [MmW] property to this value.
Default value: 8 |

Note This parameter affects instrument behavior only when the acquisition type is set to IVISCOPE_VAL_ENVELOPE. |

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. |
