3 Keysight SD1 Command Reference
3. 3. 4. 2 FPGAreadPCport
Reads data at the PCport FPGA block (Option FP1 required).
Parameters
Name Description
Inputs
moduleID (Non-object-oriented languages only)
Module identifier, returned by
open on page 28
nPCport PCport number (as if appears in the M3602A software)
address Address that appears in the PCport interface
dataSize Number of 32-bit words to read (maximum is 128 words)
addressMode Selects between the two address modes shown below:
addressMode Description Name Value
Auto
Increment Initial address is incremented
after each access ADDRESSING_AUTOINCREMENT 0
Fixed Initial address is used
for the whole access ADDRESSING_FIXED 1
accessMode Selects between the two memory access modes shown below:
accessMode Description Name Value
Non-DMA Memory access is split into multiple accesses NONDMA 0
DMA Memory access is done with a DMA transaction DMA 1
errorIn (LabVIEW only) If it contains an error, the function will not be executed and errorIn will be
passed to errorOut
Outputs
data Rx data buffer
moduleIDout (LabVIEW only) A copy of moduleID
errorOut See Error Codes on page 83
