 |
instrument handle The instrument handle that you obtain from the IviUpconverter Initialize VI or IviUpconverter Initialize With Options VI. The handle identifies a particular instrument session. Default Value: None |
 |
I offset (0.0 %) Pass an origin offset voltage to the I signal. The range of allowable values is -100% to +100%. The driver uses this value to set the IviUpconverter IQ Impairment I Offset [IQI] property. Default Value: 0.0 % |
|
|
Q offset (0.0 %) Pass the origin offset voltage to the Q signal. The range of allowable values is -100% to +100%. The driver uses this value to set the IviUpconverter IQ Impairment Q Offset [IQI] property. Default Value: 0.0 % |
|
|
ratio (0.0 %) Pass the gain imbalance between the I and Q channels. For no imbalance this value is set to 0%. The driver uses this value to set the IviUpconverter IQ Impairment Ratio [IQI] property. Default Value: 0.0 % |
 |
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. |
|
|
skew (0.0 Degree) Pass the adjustment of the phase angle between the I and Q vectors. If this skew is zero, the phase angle is 90 degrees. The driver uses this value to set the IviUpconverter IQ Impairment Skew [IQI] property. Default Value: 0.0 Degree |
 |
instrument handle out The instrument handle that you obtain from the IviUpconverter Initialize VI or IviUpconverter Initialize With Options VI. The handle identifies a particular instrument session. Default Value: None |
 |
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. |
