Short Name: IQ Rate (S/s)
Property of niRFSG
This property specifies the I/Q rate of the arbitrary waveform. The I/Q rate is coerced to a value the hardware can achieve. Read this value back after setting it to see the actual I/Q rate. NI-RFSG internally uses an FIR filter with flat response up to (0.4 × IQ rate). Given a desired signal with the maximum frequency content f, sample the signal at an I/Q rate greater than or equal to (f/0.4).
This property only applies when the Generation Mode property is set to Arb Waveform or Script.
To set this property, the NI-RFSG device must be in the Configuration state.
Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672/5673/5673E, PXIe-5820/5840
The following table lists available I/Q rates.
|PXIe-5644/5645||Up to 120 MS/s.|
|PXIe-5646||Up to 250 MS/s.|
|PXI-5670||50 MS/s, 100 MS/s|
|PXI-5671||50 MS/s, 100 MS/s, and (100 MS/s)/n, where n is divisible by 2 between 12 to 512, and divisible by 4 between 512 to 1,024 (n = 12,14,16, ...,512, 516, 520, ...,1024). Setting the I/Q rate to one of these values enables the DUC.|
|PXIe-5672||Up to 100 MS/s.|
|PXIe-5673/5673E||Up to 200 MS/s.
|PXIe-5820/5840||Up to 1.25 GS/s.|
Setting this property to 50 MS/s on the PXI-5670/5671, PXIe-5672 has the following implications:
