Short Name: Preferred Packet Size
Property of niRFSG
Specifies the preferred size of the data field in a PCI Express read request packet.
In general, the larger the packet size, the more efficiently the device uses the bus. By default, RF signal generators use the largest packet size allowed by the system. However, due to different system implementations, some systems may perform better with smaller packet sizes.
Recommended values for this property are powers of two between 64 and 512.
|Note In some cases, the RF signal generator generates packets smaller than the preferred size you set with this property.|
Supported Devices: PXI-5670/5671, PXIe-5672/5673/5673E
