Short Name: Digital Equalization Enabled

Property of niRFSG

When this property is enabled, NI-RFSG equalizes the waveform data to correct for variations in the response of the NI-RFSG device. Enabling digital equalization improves the modulation error ratio (MER) and error vector magnitude (EVM) for signals with large bandwidths (>500 kHz), but it increases tuning times.

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.

On the PXI-5670/5671, equalization is performed in the software, so tuning time is increased. On the PXIe-5672, equalization is performed in the hardware so that there is no compromise in performance.

PXIe-5644/5645/5646, PXIe-5820/5840: Enable is the only supported value for this device.

Supported Devices: PXIe-5644/5645/5646, PXI-5670/5671, PXIe-5672, PXIe-5820/5840

Default Values:

PXI-5670/5671: Disable

PXIe-5644/5645/5646, PXIe-5672, PXIe-5820/5840: Enable
