niRFSA Initialize

Creates a new session for the device. This VI 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 the Initialize With Options VI 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.

resource name 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.

id query specifies whether NI-RFSA performs an ID query.

reset specifies whether you want 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.

error in (no error) describes error conditions that occur before this VI runs.

	status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning. The default is an empty string.

instrument handle identifies your instrument session.

error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI produces.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code the error or warning code. If status is TRUE, code is a non-zero error code. If status is FALSE, code is 0 or a warning code.
	source describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning.
