Rfsg
Writes an arbitrary waveform to the NI-RFSG, starting from the position of the last data written in onboard memory.
Namespace: NationalInstruments.ModularInstruments.NIRfsg
Assembly: NationalInstruments.ModularInstruments.NIRfsg.Fx45 (in NationalInstruments.ModularInstruments.NIRfsg.Fx45.dll) Version: 2025
Syntax
public void WriteWaveform( string name, double[] iData, double[] qData )
Public Sub WriteWaveform ( name As String, iData As Double(), qData As Double() )
Parameters
- name String
- Specifies the name used to identify the waveform. This string is case-insensitive and alphanumeric, and it does not use reserved words.
- iData Double
- Specifies the in-phase (I) component of the complex baseband signal.
- qData Double
- Specifies the quadrature (Q) component of the complex baseband signal.
Exceptions
| Exception | Condition |
|---|---|
| ObjectDisposedException | The WriteWaveform(String, Double, Double) method was accessed after the associated NIRfsg object was disposed. |
Remarks
This method takes the I and Q vectors of a complex baseband signal as data input. If the waveform is large, use the
AllocateWaveform(String, Int32) method.
The NI-RFSG must be in the Configuration state before you call the WriteWaveform(String, Double, Double) method.
