 |
frequency step scaling (Linear) Pass the spacing of the steps. The driver uses this value to set the IviUpconverter Frequency Step Scaling [FST] property. Valid Values: IVIUPCONVERTER_VAL_FREQUENCY_STEP_SCALING_LINEAR - Enables linear scaling. IVIUPCONVERTER_VAL_FREQUENCY_STEP_SCALING_LOGARITHMIC - Enables logarithmic scaling. Default value: IVIUPCONVERTER_VAL_FREQUENCY_STEP_SCALING_LINEAR |
 |
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 |
 |
frequency step start (500.0e3 Hz) Pass the start frequency of the stepped sweep. The driver uses this value to set the IviUpconverter Frequency Step Start [FST] property. Default Value: 500.0e3 Hz Notes: (1) If the stop frequency is less than the start frequency, the frequency decreases during the sweep. |
|
|
frequency step stop (5.0e6 Hz) Pass the stop frequency of the stepped sweep. The driver uses this value to set the IviUpconverter Frequency Step Stop [FST] property. Default Value: 5.0e6 Hz Notes: (1) If the stop frequency is less than the start frequency, the frequency decreases during the sweep. |
 |
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. |
|
|
frequency step size (100.0e3) Pass the step size. The driver uses this value to set the IviUpconverter Frequency Step Size [FST] property. Default Value: 100.0e3 Notes: (1) The units are Hertz if the IviUpconverter Frequency Step Scaling [FST] is Linear and unitless (factor) if the IviUpconverter Frequency Step Scaling [FST] is Logarithmic. |
 |
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. |
