Abstract
We describe the ATLAS Liquid Argon calorimeter (LAr) electronics used to prepare signals for the L1 trigger, studied with a standalone data acquisition system built for the commissioning of the LAr-L1 electronics. This includes calibration data used to extract gains of all LAr calorimeters and timing shifts for different layers of the electromagnetic (EM) calorimeter. Analysis tools have been developed to study the pulse shape, timing, and amplitude, which are employed for the readout of signals from both the main detector and the L1 branch. Performance studies using beam data is also shown.
