Optimum Electronics DA-404 Data Analyzer
The DA-404 is a comopact portable, ac/battery-operated test set that measures and indicates the type and magnitude of distortion present in all characters of start-stop data/telegraph signals; the monitored signal may be 5-level, and either 7-level or 8-level code (strap selectable) -- using low-level polar + 3 to + 25 volts, high-level polar (10ma), or neutral (20 or 60ma) inputs. The unit also indicates the presence of detected parity errors in 7 or 8level coded data signals.
Measurements may be made at any one of four customer-specified, standard baud-rates, ranging from 37.5 to 300 bauds. While measuring end or bias distortion (marking or spacing) the data analyzer also simultaneously indicates total peak distortion present in the signal. Used with an associated test pattern generator, the data analyzer provides a comprehensive field capability for testing and evaluating the performace of data/telegraph systems and equipment.
