IviRFSigGen Configure ALC [ALC]
IviRFSigGenALC Capability Group
This VI configures the ALC (Automatic Level Control) of the signal generator's RF output.
 |
instrument handle The instrument handle that you obtain from the IviRFSigGen Initialize or IviRFSigGen Initialize With Options VIs. |
 |
source Specifies the source of the controlling voltage for the Automatic Level Control. The RF level at the sensor point is held constant. The driver uses this value to set the IviRFSigGen>>ALC>>ALC Source property.
Defined Values: IVIRFSIGGEN_VAL_ALC_SOURCE_INTERNAL - The ALC is controlled by an internal measurement source. IVIRFSIGGEN_VAL_ALC_SOURCE_EXTERNAL - The ALC is controlled by an external voltage. Default Value: IVIRFSIGGEN_VAL_ALC_SOURCE_INTERNAL |
 |
bandwidth Specifies the bandwidth of Automatic Level Control (ALC). Narrow bandwidth impoves noise and allows AM with modulation frequencies beyond bandwidth frequency. The value is coerced to reflect the ability of the current RF signal generator. The driver uses this value to set the IviRFSigGen>>ALC>>ALC Bandwidth property.
Units: Hertz 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. |
