niRFSA_InitializeExternalAlignmentStep

ViStatus niRFSA_InitializeExternalAlignmentStep(ViSession vi, ViInt64 externalAlignmentStep);

Purpose

Initializes an EEPROM-specific external alignment step.

Supported Devices: PXIe-5605 (PXIe-5665 only), PXIe-5606 (PXIe-5668 only)

Parameters

Input
Name Type Description
vi ViSession Identifies your instrument session. vi is obtained from the niRFSA_InitializeExternalAlignment function and identifies a particular instrument session.
externalAlignmentStep ViInt64 Specifies which external alignment step you want to initialize.

NIRFSA_VAL_EXT_ALIGNMENT_PRESELECTOR Initiates preselector alignment. This step generates coefficients to align the preselector across the frequency range of 3.6 GHz to 14 GHz.

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.
