The General Radio 1134-A Analog to Digital Converter was introduced in Catalog Q (1961) and remained available through Catalog R (1963).
It is an accessory for the Type 1130-A Digital Time and Frequency Meter with the purpose to convert the meter's digital readout to analog voltage for a recorder/plotter to create a permanent record. The 1134-A can be used with any device producing digital data at the appropriate logic voltage levels.
