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 |
 |
external polarity (Normal) Pass the polarity of the external source signal. The driver uses this value to set the IviUpconverter Pulse Modulation External Polarity [PULM] property. Valid Values: IVIUPCONVERTER_VAL_PULSE_MODULATION_EXTERNAL_POLARITY_NORMAL - The upconverter modulates the carrier signal with normal pulse polarity. Increasing the positive pulse voltage level results in higher RF level. IVIUPCONVERTER_VAL_PULSE_MODULATION_EXTERNAL_POLARITY_INVERSE - The upconverter modulates the carrier signal with inverted pulse polarity. Increasing the positive pulse voltage level results in lower RF level. Default Value: IVIUPCONVERTER_VAL_PULSE_MODULATION_EXTERNAL_POLARITY_NORMAL |
 |
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 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. |
