Restores the NI-RFSA driver state to a default state to avoid RFmx using any hardware or driver state that was set by the RF toolkits or other custom NI-RFSA code.
Use this function when you switch back to using RFmx to perform measurements after you have used the NI-RFSA handle to perform measurements with RF toolkits or you have used other custom NI-RFSA code. Unlike the RFmxInstr_ResetToDefault function, the RfmxInstr Reset Driver function does not reset RFmx attributes configured on the RFmx session. Hence, you do not need to set RFmx attributes again when switching back to RFmx measurements. Refer to RFmx SpecAn CHP - WCDMA ModAcc - CHP Example (LabVIEW) for more information about using RFmx to perform measurements.

Syntax

int32 __stdcall RFmxInstr_ResetDriver(niRFmxInstrHandle instrumentHandle, char selectorString[])

Parameters

NameDirectionTypeDescription
instrumentHandle[in]niRFmxInstrHandle

This parameter identifies the instrument session. This parameter is obtained from the RFmxInstr_Initialize function or the RFmxInstr_InitializeFromNIRFSASessionArray function.

selectorString[in]char

Returns

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 RFmx 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 RFmxInstr_GetError function.

The general meaning of the status code is as follows:
