Abstract: : In this paper, the equipment for calibration and reparation of analog cards in the Teledyne data acquisition system is presented. The Teledyne data acquisition system is used for data acquisition of sensor’s signals in the wind tunnel. It consists of several different card types: a digital data processor card, a setup card, an analog multiplexer card, a card with analog digital converter, 2 digital input cards and 32 analog cards. Analog cards measure analog sensor’s voltages. They are the main part of the Teledyne data acquisition system. The analog cards calibration software is developed and it is used in combination with high precision calibrator. The testing equipment is developed for reparation of analog cards. It enables reparation of the analog cards without the Teledyne data acquisition system, and also makes approach to analog card with the scope.

Key words: data acquisition system, wind tunnel, analog card, remote control, equipment.
