IviScope Configure Reference Levels
IviScopeWaveformMeas Capability Group [WM]
This VI configures the reference levels for waveform measurements.
You must call this VI before you call the IviScope Read Waveform Measurement VI to take measurements.
 |
instrument handle The instrument handle that you obtain from the IviScope Initialize or the IviScope Initialize With Options VI. |
 |
low ref (percentage) Pass the low reference you want the oscilloscope to use for waveform measurements. The driver sets the IviScope Measurement Low Reference [WM] property to this value.
Units: A percentage of the difference between the Voltage High and Voltage Low. |
 |
Note The oscilloscope calculates the Voltage High and the Voltage Low using either the min/max or histogram methods. The min/max method uses the maximum and minimum values found. The histogram method uses the most common values found above and below the middle of the waveform. |
|
mid ref (percentage) Pass the mid reference you want the oscilloscope to use for waveform measurements. The driver sets the IviScope Measurement Mid Reference [WM] property to this value.
Units: A percentage of the difference between the Voltage High and Voltage Low. |
|
Note The oscilloscope calculates the Voltage High and the Voltage Low using either the min/max or histogram methods. The min/max method uses the maximum and minimum values found. The histogram method uses the most common values found above and below the middle of the waveform. |
|
high ref (percentage) Pass the high reference you want the oscilloscope to use for waveform measurements. The driver sets the IviScope Measurement High Reference [WM] property to this value.
Units: A percentage of the difference between the Voltage High and Voltage Low. |
|
Note The oscilloscope calculates the Voltage High and the Voltage Low using either the min/max or histogram methods. The min/max method uses the maximum and minimum values found. The histogram method uses the most common values found above and below the middle of the waveform. |
 |
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. |
