Using the Software Results Run-Time Data Display Most procedures generate data output. While the procedure is running, the data is displayed in a temporary HTML page, which opens automatically for each individual procedure. The HTML pages that are opened during the procedure run then are then closed once the specific procedure is finished.
Page 29: Sata Parameters
Using the Software SATA Parameters Sequence Parameters The sequencer parameters control the flow of the test sequencer only, but not the behavior of individual procedures. They are identical across all versions of ValiFrame. One such parameter, namely Repetitions, is available for all procedures and groups in the procedure tree. The others are only available for specific procedures.

Page 32: Calibration Overview
SATA Calibrations Calibration Overview Before any receiver test procedure can be run, the SATA receiver test system must be calibrated. The ValiFrame calibration plane is given by the DUT input ports. The receiver test signal characteristics such as the signal generator output voltage level and jitter parameters are typically affected by the signal transmission between the generator output ports and the DUT input ports.
