IviUpconverter Configure AM [AM]
IviUpconverterModulateAM Capability Group
This VI configures the modulation source, scaling, and depth for the upconverter's amplitude modulation.

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 |
 |
source ("") Pass the source of the signal that is used as the modulating signal. If more than one source is specified, the voltages of all sources are summed. Multiple source names are separated by commas. The driver uses this value to set the IviUpconverter AM Source [AM] property. Default Value: "" |
 |
scaling (Linear) Pass linear or logarithmic characteristics for amplitude modulation. The unit of the IviUpconverter AM Depth [AM] property is changed with this setting. The driver uses this value to set the IviUpconverter AM Scaling [AM] property. Valid Values: IVIUPCONVERTER_VAL_AM_SCALING_LINEAR - Enables linear attenuation for amplitude modulation. IVIUPCONVERTER_VAL_AM_SCALING_LOGARITHMIC - Enables logarithmic attenuation for amplitude modulation. Default Value: IVIUPCONVERTER_VAL_AM_SCALING_LINEAR |
 |
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. |
 |
depth (0.0) Pass the extent of modulation the upconverter applies to the RF output signal with the modulating signal as a result of summing all sources, internal and external. The driver uses this value to set the IviUpconverter AM Depth [AM] property. Default Value: 0.0 Notes: (1) If the IviUpconverter AM Scaling [AM] property is set to Linear, then the units are percent (%). If the IviUpconverter AM Scaling [AM] property is set to logarithmic, then the units are dBm. |
 |
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. |
