Access | High Level Functions |
|---|---|---|
| ViInt32 | R/W | None |
Specifies the type of de-embedding to apply to measurements on the specified port.
To use this attribute, you must use the channelName parameter of the niRFSG_SetAttributeViInt32 function to specify the name of the port to configure for de-embedding.
If you set this attribute to NIRFSG_VAL_DEEMBEDDING_TYPE_SCALAR or NIRFSG_VAL_DEEMBEDDING_TYPE_VECTOR, NI-RFSG adjusts the instrument settings and the returned data to remove the effects of the external network between the instrument and the DUT.
PXIe-5831/5832: NIRFSA_VAL_DEEMBEDDING_TYPE_VECTOR is only supported for TRX Ports.
Defined Values:
| NIRFSG_VAL_DEEMBEDDING_TYPE_NONE (3900) | De-embedding is not applied to the measurement. |
|---|---|
| NIRFSG_VAL_DEEMBEDDING_TYPE_SCALAR (3901) | De-embeds the measurement using only the gain term. |
| NIRFSG_VAL_DEEMBEDDING_TYPE_VECTOR (3902) | De-embeds the measurement using the gain term and the reflection term. |
| Default Value: NIRFSG_VAL_DEEMBEDDING_TYPE_SCALAR |
Valid Values for PXIe-5830/5840/5841 : NIRFSA_VAL_DEEMBEDDING_TYPE_SCALAR or NIRFSA_VAL_DEEMBEDDING_TYPE_NONE
Valid Values for PXIe-5831/5832: NIRFSA_VAL_DEEMBEDDING_TYPE_VECTOR, NIRFSA_VAL_DEEMBEDDING_TYPE_SCALAR, or NIRFSA_VAL_DEEMBEDDING_TYPE_NONE
Supported Devices: PXIe-5830/5831/5832/5840/5841

| ViString | R/W | None |
Selects the de-embedding table to apply to the measurements on the specified port.
To use this attribute, you must use the channelName parameter of the niRFSG_SetAttributeViString function to specify the name of the port to configure for de-embedding.
If de-embedding is enabled, NI-RFSG uses the specified table to remove the effects of the external network between the instrument and the DUT.
Use the niRFSG_CreateDeembeddingSparameterTableArray function to create tables.

| ViReal64 | RO | None |
Returns the de-embedding gain applied to compensate for the mismatch on the specified port. If de-embedding is enabled, NI-RFSG uses the returned compensation gain to remove the effects of the external network between the instrument and the DUT.
