IviRFSigGen Configure AM [AM]

IviRFSigGenModulateAM Capability Group

This VI configures the modulation source, scaling, and depth for the signal generator's amplitude modulation.

instrument handle The instrument handle that you obtain from the IviRFSigGen Initialize or IviRFSigGen Initialize With Options VIs.
source Specifies the source of the signal that is used as the modulating signal. If more than one source is specified, the voltages of all sources (internal and external) are summed. Multiple source names are separated by commas. The driver uses this value to set the IviRFSigGen>>Analog Modulation>>AM>>AM Source property.

Default Value: ""
scaling Specifies linear or logarithmic attenuation for amplitude modulation. The unit of the IviRFSigGen>>Analog Modulation>>AM>>AM Depth property is changed with this setting. The driver uses this value to set the IviRFSigGen>>Analog Modulation>>AM>>AM Scaling property.

Defined Values:
IVIRFSIGGEN_VAL_AM_SCALING_LINEAR
IVIRFSIGGEN_VAL_AM_SCALING_LOGARITHMIC

Default Value: IVIRFSIGGEN_VAL_AM_SCALING_LINEAR
depth Specifies the extent of modulation the signal generator applies to the RF-signal (carrier waveform) with the modulating signal as a result of summing all sources, internal and external. The driver uses this value to set the IviRFSigGen>>Analog Modulation>>AM>>AM Depth property.

Units: If the IviRFSigGen>>Analog Modulation>>AM>>AM Scaling property is set to Linear, then the units are percent (%). If the IviRFSigGen>>Analog Modulation>>AM>>AM Scaling property is set to logarithmic, then the units are dBm.

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.

instrument handle out The instrument handle that you obtain from the IviRFSigGen Initialize or IviRFSigGen Initialize With Options VIs.
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.
