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.
Specifications
- Data Input: BCD, weighted 1-2-4-2 or 1-2-2-4. Binary "1" +90 V max. Binary "0" +150 V min
- Output: 1 mA at 30 kΩ source impedance, or 100 mV across 100 Ω, positive side grounded
- Load: 2 kΩ maximum for 1 mA, 2 kΩ min. for 100mV
