The Agilent 59303A is a digital-to-analog converter that translates serial ASCII-coded digital data into analog voltage output. Operating across 48–440 Hz, this 22 VA module accepts up to 15 ASCII-coded digits serially and generates an analog voltage equivalent to three consecutive selected digits upon receipt of a line-feed character, with output spanning −10 V. Engineered for direct integration into measurement and control systems, the 59303A bridges digital instrumentation and analog devices without external processing overhead.
