ViStatus niRFSA_CalAdjustIFAttenuationCalibration(ViSession vi, ViConstString channelName, ViInt32 IFFilter, ViInt32 numberOfAttenuators, ViReal64* attenuatorSettings, ViReal64 measurement);
Purpose
Specifies the IF attenuation settings.
Supported Devices: PXIe-5601, PXIe-5694
Parameters
| Input | ||||||||||
| Name | Type | Description | ||||||||
| vi | ViSession | Identifies your instrument session. vi is obtained from the niRFSA_InitExtCal function and identifies a particular instrument session. | ||||||||
| channelList | ViConstString | Identifies which channels to apply settings. Specify an empty string as the value of this parameter. | ||||||||
| IFFilter | ViInt32 | Specifies the IF filter used by the downconverter.
|
||||||||
| numberOfAttenuators | ViInt32 | Specifies the number of attenuators to use during the IF attenuation adjustment. | ||||||||
| attenuatorSettings | ViReal64* | Specifies the IF attenuator settings for the measurement. The first element in the array corresponds with IF1, the next element corresponds to IF2, and so on. | ||||||||
| measurement | ViReal64 | Specifies the relevant measurement taken for the current configuration. | ||||||||
Return Value
| Name | Type | Description | ||||||||
| status | ViStatus | Returns the status code of this operation. The status code either indicates success or describes an error or warning condition. Examine the status code from each call to an NI-RFSA function to determine if an error has occurred. To obtain a text description of the status code and additional information about the error condition, call the niRFSA_GetError function. To clear the error information from NI-RFSA, call the niRFSA_ClearError function. The general meaning of the status code is as follows:
