Syntax
NIRFSG_ATTR_IQ_OUT_PORT_TERMINAL_CONFIGURATION
Numeric Value | Data Type | Access | Applies To |
|---|---|---|---|
1150146 | ViInt32 | Read/Write | Channels |
Remarks
If you set this attribute to NIRFSG_VAL_SINGLE_ENDED, you must terminalinate the negative I and Q output connectors with a 50 Ohm termination.
If you set this attribute to NIRFSG_VAL_SINGLE_ENDED, the positive I and Q connectors generate the resulting waveform. If you set this attribute to NIRFSG_VAL_DIFFERENTIAL, both the positive and negative I and Q connectors generate the resulting waveform.
To use this attribute, you must use the channelName parameter of the niRFSG_SetAttributeViInt32 function to specify the name of the channel you are configuring. For the PXIe-5645, you can configure the I and Q channels by using I or Q as the channel string, or set the channel string to "" (empty string) to configure both channels. For the PXIe-5820, the only valid value for the channel string is "" (empty string).
For the PXIe-5645, this attribute is ignored if you are using the RF ports.
To set this attribute, the NI-RFSG device must be in the Configuration state.
Defined Values:
Name | Value | Description |
|---|---|---|
NIRFSG_VAL_DIFFERENTIAL | 15000 (0x3a98) | Sets the terminal configuration to differential. |
NIRFSG_VAL_SINGLE_ENDED | 15001 (0x3a99) | Sets the terminal configuration to single-ended. |
Default Value:NIRFSG_VAL_DIFFERENTIAL
PXIe-5820: The only valid value for this attribute is NIRFSG_VAL_DIFFERENTIAL.
Supported Devices: PXIe-5645, PXIe-5820
