The General Radio 1620-A Capacitance-Measurement Assembly was introduced in Catalog R (1963) and remained available through Catalog 1978.

The Type 1620-A Capacitance-Measurement Assembly is based on a compilation of Types 1240-A Oscillator/Null Detector and 1615-A Capacitance Bridge into a single unit. Early models were connected physically by bolting their aluminum end frames together. Later models were rack-mounted in a purpose-built cabinet.
