• [niFgen_DefineUserStandardWaveform]|

Specifies which standard waveform the signal generator produces.

Use this attribute only when the NIFGEN_ATTRIBUTE_OUTPUT_MODE attribute is set to NIFGEN_VAL_OUTPUT_FUNC.

Defined Values

NIFGEN_VAL_WFM_SINE	Sinusoid waveform
NIFGEN_VAL_WFM_SQUARE	Square waveform
NIFGEN_VAL_WFM_TRIANGLE	Triangle waveform

NIFGEN_VAL_WFM_NOISE	White noise
NIFGEN_VAL_WFM_USER	User-defined waveform as defined with the niFgen_DefineUserStandardWaveform function

Default Value: NIFGEN_VAL_WFM_SINE

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1250102	ViReal64	R/W	Channel	None	niFgen_ConfigureStandardWaveform

Controls the amplitude of the standard waveform that the signal generator produces. This value is the amplitude at the output terminal.

For example, to produce a waveform ranging from –5.00 V to +5.00 V, set this attribute to 10.00 V.

Note:   This parameter does not affect signal generator behavior when you set the waveform parameter of the niFgen_ConfigureStandardWaveform function to NIFGEN_VAL_WFM_DC.

Units: Vpk-pk

Default Value: None

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1250103	ViReal64	R/W	Channel	None	niFgen_ConfigureStandardWaveform

Controls the DC offset of the standard waveform that the signal generator produces. This value is the offset at the output terminal. The value is the offset from ground to the center of the waveform that you specify with the waveform parameter of the niFgen_ConfigureStandardWaveform function.

For example, to configure a waveform with an amplitude of 10.00 V to range from 0.00 V to +10.00 V, set this attribute to 5.00 V.

Units: volts

Default Value: None

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1250105	ViReal64	R/W	Channel	None	niFgen_ConfigureStandardWaveform

Controls horizontal offset of the standard waveform the signal generator produces. Specify this attribute in degrees of one waveform cycle.

A start phase of 180 degrees means output generation begins halfway through the waveform. A start phase of 360 degrees offsets the output by an entire waveform cycle, which is identical to a start phase of 0 degrees.

Note:   This parameter does not affect signal generator behavior when you set the waveform parameter of the niFgen_ConfigureStandardWaveform function to NIFGEN_VAL_WFM_DC.

Units: Degrees of one cycle

Default Value: None

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1250106	ViReal64	R/W	Channel	None	None

Controls the duty cycle of the square wave the signal generator produces. Specify this attribute as a percentage of the time the square wave is high in a cycle.

Note:   This parameter only affects signal generator behavior when you set the waveform parameter of the niFgen_ConfigureStandardWaveform function to NIFGEN_VAL_WFM_SQUARE.

Units: Percentage of time the waveform is high

Default Value: 50%

Numeric Value	Data Type	Access	Applies to	Coercion	High-Level Functions
1150105	ViReal64	R/W	N/A	None	None

Controls the duty cycle of the square wave the signal generator produces on the SYNC OUT connector. Specify this attribute as a percentage of the time the square wave is high in each cycle.

Units: Percentage of the time the waveform is high

Default Value: 50%

1250104	ViReal64	R/W	Channel	None	niFgen_ConfigureStandardWaveform

Controls the frequency of the standard waveform that the signal generator produces.

Notes  This parameter does not affect signal generator behavior when you set the waveform parameter of the niFgen_ConfigureStandardWaveform function to NIFGEN_VAL_WFM_DC.

For NIFGEN_VAL_WFM_SINE, the range is between 0 MHz and 16 MHz, but the range is between 0 MHz and 1 MHz for all other waveforms. Units: hertz (Hz)

Default Value: None

Numeric Value	Data type	Access	Applies to	Coercion	High Level Functions
1150239	ViInt32	R/W	N/A	None	None

Specifies the maximum number of samples that can be used in the standard function waveform buffer. Increasing this value may increase the quality of the waveform. This attribute is valid only on devices that implement Standard Function output mode in software, and it is read-only for all other devices.
