RFmxNR_CHPCfgSweepTime

int32 __stdcall RFmxNR_CHPCfgSweepTime (niRFmxInstrHandle instrumentHandle, char selectorString[], int32 sweepTimeAuto, float64 sweepTimeInterval);

Purpose

Configures the sweep time.

Parameters

Input
Name Type Description
instrumentHandle niRFmxInstrHandle Specifies the instrument session. The RFmx driver obtains this parameter from the RFmxNR_Initialize function.
selectorString char[] Specifies a selector string comprising of the signal name. If you do not specify the signal name, the default signal instance is used.
Example:
"signal::sig1"
You can use the RFmxNR_BuildSignalString function to build the selector string.
sweepTimeAuto int32 Specifies whether the measurement sets the sweep time.
RFMXNR_VAL_CHP_SWEEP_TIME_AUTO_FALSE (0) The measurement uses the sweep time that you specify in the sweepTimeInterval parameter.
RFMXNR_VAL_CHP_SWEEP_TIME_AUTO_TRUE (1) The measurement calculates the sweep time internally. For DL, the sweep time is calculated based on the value of the RFMXNR_ATTR_OBW_RBW_FILTER_BANDWIDTH attribute, and for UL, it uses a sweep time of 1 ms.
sweepTimeInterval float64 Specifies the sweep time when you set the sweepTimeAuto parameter to RFMXNR_VAL_CHP_SWEEP_TIME_AUTO_FALSE. This value is expressed in seconds.

Return Value

Name Type Description
status int32 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 RFmxNR_GetError function.

The general meaning of the status code is as follows:
