A programmable calibrating pulse generator with multi-outputs and very high stability

We present a very precise and stable pulse generator to be used for the calibration of an array of large mass bolometric detectors. The realized instrument is characterized by the presence of multi-outputs and is completely programmable in pulse width and amplitude. Triggering is allowed with a dedicated line. Although featuring ppm//spl deg/C stability, it was realized exploiting commercial devices, obtaining a very cheap solution.
