niRFSA_init

niRFSA_init

ViStatus = niRFSA_init ( ViRsrc resourceName, ViBoolean IDQuery, ViBoolean reset, ViSession* vi);

Purpose

Creates a new session for the device. This function performs the following initialization actions:

• Creates a new instrument driver session to the RF signal analyzer, using the downconverter resource name you specify.
• Sends initialization commands to reset both hardware modules to a known state necessary for NI-RFSA operation.

Note  Before initializing the NI 5661, an NI 5142 IF digitizer module must be associated with the NI 5600 downconverter module in MAX. After association, pass the NI 5600 device name to this VI to initialize both modules. To change the digitizer association, modify the NI 5600 Properties page in MAX, or use this function to override the association in MAX. Refer to the NI RF Vector Signal Analyzers Getting Started Guide, installed at Start»Programs»National Instruments»NI-RFSA»Documentation for information on MAX association.

Parameters

Input
Name	Type	Description
resourceName	ViRsrc	Specifies the resource name of the device to initialize. Example # Device Type Syntax 1 myDAQmxDevice NI-DAQmx device, device name = "myDAQmxDevice" 2 myLogicalName IVI logical name or virtual instrument, name = "myLogicalName" For NI-DAQmx devices, the syntax is the device name specified in MAX, as shown in Example 1. Typical default names for NI-DAQmx devices in MAX are Dev1 or PXI1Slot1. You can rename an NI-DAQmx device by right-clicking on the name in MAX and entering a new name. You can also pass in the name of an IVI logical name configured with the IVI Configuration utility. For additional information, refer to the IVI topic in the Measurement & Automation Explorer Help. Caution   NI-DAQmx device names are not case-sensitive. However, all IVI names, such as logical names, are case-sensitive. If you use an IVI logical name, make sure the name is identical to the name shown in the IVI Configuration Utility.
IDQuery	ViBoolean	Specifies whether NI-RFSA performs an ID query.
reset	ViBoolean	Specifies whether you want the to reset the NI-RFSA device during the initialization procedure. TRUE means that the device is reset; FALSE means that the device is not reset. FALSE is the default value.
Output
Name	Type	Description
vi	ViSession	Identifies your instrument session.
