• Low Latency control operation:
  • Target push data transfer to slave memory on host card.
  • Data is delivered with minimum latency after the sample clock.

• For overview, please refer to
  • http://www.d-tacq.com/resources/D-Tacq_2G_UserGuide.pdf

• For operating instructions, please refer to
  • README.ACQ196 readme file for ACQ196 operation
  • README.ACQ216 readme file for ACQ216 operation
  • README.AO32 readme file for AO32 operation
    • ao-ramps.png

  • README.RFM readme file for RFM/"ALTERNATE TARGET" operation

• as a consequence of evolution, llcontrol has many operating modes
  • SOFT -> ECM -> syncECM -> SYNC2V
  • SYNC2V is the prefered mode.
    • SYNC2V_AO32 : SYNC2V with output to AO32 cards
    • SYNC2V+ALT : alternate VI destination eg RFM. NB ALT does NOT affect llcontrol AT ALL.

• llcontrol-core.c implements the core of the llcontrol loop, and ECM mode
• llcontrol-sync2v-core.c implements SYNC_2V mode
• llcontrol-sync2VAO32-core.c detail of AO32CPCI control

• llcontrol-syncECM-core.c implements "SYNC_ECM mode"
• llcontrol-acq216-core.c detail of ACQ216 control
