niFgen Configure Frequency List
Configures the properties of the signal generator that affect frequency list generation. Selects the frequency list to produce and sets the amplitude, DC offset, and start phase.
 |
Notes The signal generator must not be in the Generating state when you call this VI. You must set Output Mode to Frequency List using niFgen Configure Output Mode VI before calling this VI. |
 |
Instrument Handle identifies your instrument session. Instrument Handle was obtained from the niFgen Initialize VI or niFgen Initialize With Options VI. | ||||||
 |
DC Offset specifies the DC offset of the standard waveform that you want the signal generator to produce. This value is the offset at the output terminal. The value is the offset from ground to the center of the waveform you specify with the Waveform parameter.
For example, to configure a waveform with an amplitude of 10.00 V to range from 0.00 V to +10.00 V, set the DC Offset to 5.00 V.
Units: volts |

Channel Name specifies the channel this VI uses. | ||||||
 |
Frequency List Handle specifies the handle of the frequency list you want the signal generator to produce. You can create multiple frequency lists using niFgen Create Frequency List VI. niFgen Create Frequency List returns a handle that you use to identify each list. | ||||||
|
Amplitude specifies the amplitude of the standard waveform that you want the signal generator to produce. 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 Amplitude to 10.00 V. Units: Vpk-pk

|
Start Phase specifies the horizontal offset of the standard waveform that you want the signal generator to produce. Specify this parameter in degrees of one waveform cycle. NI-FGEN sets Start Phase to this value (measured in degrees of one 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 and is therefore identical to a start phase of 0 degrees.

 |
error in describes error conditions that occur before this VI or function runs.
| ||||||
 |
Instrument Handle Out passes a reference to your instrument session to the next VI. | ||||||
 |
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces.
