Configures the source of measurement settings for applying DPD.

Syntax

int32 __stdcall RFmxSpecAn_DPDCfgApplyDPDConfigurationInput(niRFmxInstrHandle instrumentHandle, char selectorString[], int32 configurationInput)

Parameters

NameDirectionTypeDescription
instrumentHandle[in]niRFmxInstrHandle

This parameter specifies the RFmx session refnum. Instrument Handle In is obtained from the RFmxInstr_Initialize function.

selectorString[in]char

This parameter specifies a Selector String comprising of the signal name. If you do not specify the signal name, the default signal instance is used. The default value is "" (empty string).
Example:
""
"signal::sig1"
You can use the RFmxSpecAn_BuildSignalString function to build the selector string.

configurationInput[in]int32

This parameter specifies the mode of configuring parameters for applying DPD. The default value is Measurement.

Description

RFMXSPECAN_VAL_DPD_APPLY_DPD_CONFIGURATION_INPUT_MEASUREMENT

0 (0x0)

Uses the computed DPD polynomial or lookup table for applying DPD on an input waveform using the same RFmx session handle. The configuration parameters for applying DPD such as the RFMXSPECAN_ATTR_DPD_DUT_AVERAGE_INPUT_POWER, RFMXSPECAN_ATTR_DPD_MODEL, RFMXSPECAN_ATTR_DPD_MEASUREMENT_SAMPLE_RATE, DPD polynomial, and lookup table are obtained from the DPD measurement configuration.

RFMXSPECAN_VAL_DPD_APPLY_DPD_CONFIGURATION_INPUT_USER

1 (0x1)

Applies DPD by using a computed DPD polynomial or lookup table on an input waveform. You must set the configuration parameters for applying DPD such as the RFMXSPECAN_ATTR_DPD_APPLY_DPD_USER_DUT_AVERAGE_INPUT_POWER, RFMXSPECAN_ATTR_DPD_APPLY_DPD_USER_DPD_MODEL, RFMXSPECAN_ATTR_DPD_APPLY_DPD_USER_MEASUREMENT_SAMPLE_RATE, DPD polynomial, and lookup table. You do not need to call the RFmxSpecAn_Initiate function when you set the DPD Apply DPD Config Input attribute User.

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 RFmxSpecAn_GetError function.

The general meaning of the status code is as follows:
