Abstract :
The SVX (silicon vertex detector) data acquisition system includes three components: a Fastbus sequencer, an SVX rabbit crate controller, and a digitizer. These modules are integrated into the Collider Detector Facility (CDF) data acquisition system and operate the readout chips. The results of the extensive functional tests of the SVX modules are reported. The authors discuss the sequencer´s stability, systematic differences between them, and methods of synchronization with the Tevatron beam crossing. The digitizer ADC (analog-to-digital converter) calibration procedure run on the microsequencer is described. The microsequencer code used for data taking and SVX chip calibration modes is described. Measurements of the SVX data scan time under different conditions are discussed.<>
