Register Based Settings:Source Increment Count Specifies the number of elements by which to increment the source address on block move operations. Valid values include 0 and 1. The default is 1. If this property is set to 0, VISA Move In X operations always read from the same element, essentially treating the source as a FIFO register. Details
PXI/PCI Settings:Express Settings:D-Star Bus Number Returns the differential star bus number of this device. A value of -1 means that the chassis is unidentified or does not have a timing slot. Details
PXI/PCI Settings:Express Settings:D-Star Set Returns the set of differential star lines connected to this device. A value of -1 means that the chassis is unidentified or does not have a timing slot. Details
