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