Obsolete Attributes

NIRFSG_ATTR_IQ_ENABLED [OBSOLETE]

|Numeric Value|Data
type|Access|Coercion|High Level Functions| |1250401|ViBoolean|R/W|None|niRFSG_ConfigureIQEnabled|

Description

|Note|Note  This attribute is obsolete and should not be used.| Enables or disables IQ (vector) modulation of the output signal. Enabling this attribute is required for generating arbitrary signals. To set this attribute, the NI-RFSG device must be in the Configuration state.

Defined Values:

|VI_TRUE|IQ modulation is enabled.| |VI_FALSE|IQ modulation is disabled.| Default Value: VI_FALSE

NIRFSG_ATTR_UPCONVERTER_CENTER_FREQUENCY_INCREMENT [OBSOLETE]

|Data
type|Access|Coercion|High Level Functions| |ViReal64|R/W|None|None|

Description

|Note|Note  This attribute is obsolete and should not be used.| Affects which upconverter center frequencies are used. You can use this attribute to speed up frequency sweeps by reducing the number of times the upconverter retunes.

If the upconverter center frequency (UCF) is explicitly set, the UCF is selected according to the following formula:

UCF anchor + (UCF increment·k)

where    k is any positive or negative integer

Units: hertz (Hz)

Supported Devices: PXIe-5672

NIRFSG_ATTR_UPCONVERTER_CENTER_FREQUENCY_INCREMENT_ANCHOR [OBSOLETE]

|Data
type|Access|Coercion|High Level Functions| |ViReal64|R/W|None|None|

Description

|Note|Note  This attribute is obsolete and should not be used.| Specifies the reference point for the upconverter center frequencies to use. You can use this attribute to speed up frequency sweeps by reducing the number of times the upconverter retunes.

If explicitly set, the upconverter center frequency (UCF) is selected according to the following formula:

UCF anchor + (UCF increment · k)

where     k is any positive or negative integer

Units: hertz (Hz)

Supported Devices: PXIe-5672

NIRFSG_ATTR_SAMPLE_CLOCK_RATE [OBSOLETE]

|Data
type|Access|Coercion|High Level Functions| |ViReal64|R/W|None|niRFSG_ConfigureRefClock|

Description

Specifies the sample rate at which the arbitrary waveform was produced, expressed in samples per second. Use the NIRFSG_ATTR_IQ_RATE attribute in place of this attribute.

Defined Values:

|Value|Description| |50E6|50 MS/s| |100E6|100 MS/s|

NIRFSG_ATTR_EXTERNAL_CALIBRATION_USER_DEFINED_INFO [OBSOLETE]

|Numeric Value|Data
type|Access|Coercion|High Level Functions| |1150078|ViString|R/W|None|None|

Description

|Note|Note  This attribute is obsolete and should not be used.| Specifies a string that contains arbitrary, user-defined information that is stored with external calibration data.

Supported Devices: PXI-5610, PXIe-5611, PXI/PXIe-5650/5651/5652, PXIe-5653, PXI-5670/5671, PXIe-5672/5673/5673E

NIRFSG_ATTR_EXTERNAL_CALIBRATION_USER_DEFINED_INFO_MAX_SIZE [OBSOLETE]

|Numeric Value|Data
type|Access|Coercion|High Level Functions| |1150079|ViInt32|R/W|None|None|

Description

|Note|Note  This attribute is obsolete and should not be used.| Returns the maximum string length for the NIRFSG_ATTR_EXTERNAL_CALIBRATION_USER_DEFINED_INFO attribute.

Supported Devices: PXI-5610, PXIe-5611, PXI/PXIe-5650/5651/5652, PXIe-5653, PXI-5670/5671, PXIe-5672/5673/5673E
